Abstract :

Developing efficient photocatalysts is one of green and low cost tactic for addressing the environmental deterioration and energy crisis. Therefore, it remains a fantastic and important strategy to design an efficient junction between different semiconductors for harvesting solar light, boosting the redox capability. Herein, the fabrication of ZnS in situ decorated CdIn2S4 (referred to as CIS-Zx) were prepared by converting ZnS particles on Cd2In4S surface by a facile cation exchange method during solvothermal synthesis. According to a series of PEC measurements and DFT calculations, the bending of band edge as well as the establishing of built-in electric field in the interface of CIS/ZnS heterojunction were concluded, causing the formation of in-situ S-scheme heterojunctions in CdIn2S4/ZnS. The in-situ S-scheme heterojunctions can effectively ameliorate the migration behaviors of photo-generated charges. Compared with pure CdInS4, ZnS and physically mixed CdIn2S4/ZnS, the CIS-Zx in-situ S-scheme heterojunction exhibits efficient photocatalytic activity and stability in the selective reduction of aromatic nitro compounds and oxidation of aromatic alcohols, it is hoped that this work will open up a new avenue for innovative applications of in-situ S-scheme heterojunctions.

Abstract :

金属有机框架(MOFs)材料因其高孔隙率特性在气体吸附分离、药物传递、催化等领域具有广泛应用.近年来,将功能化纳米颗粒(NPs)封装在MOFs中的研究在催化领域引起了科学家的兴趣.其中,较大比表面积的MOFs可以为NPs的分散和固定提供理想的平台,而NPs反过来可以为催化反应引入更多的活性位点,提高催化效率.然而, MOFs本身的孔隙常局限于微孔(<2 nm),这极大地限制了NPs在MOFs孔隙中的有效封装.因此,设计并制备含有介孔(2-50 nm)或大孔(>50nm)的多级孔MOFs,揭示其孔径大小对复杂NPs/MOFs复合催化剂催化性能的影响具有重要意义.然而,具有不同孔径MOFs的可控制...

Abstract :

It is fascinating yet challenging to assemble anisotropic nanowires into ordered architectures of high complexity and intriguing functions. We exploited a facile strategy involving oriented etching of a metal-organic fragment (MOF) to advance the rational design of highly ordered nanostructures. As a proof of concept, a microscale MIL-68(In) single crystal was etched with a K-3[Co(CN)(6)] solution to give a microtube composed of aligned MIL-68(In) nanorods. Annealing such a MIL-68(In) microtube readily created an unprecedented branched In2O3 mesocrystal by assembly of In2O3 nanorods aligned in order. The derived ordered-In2O3-ZnIn2S4 is more efficient in catalyzing visible-light-driven H-2 evolution (8753 mu mol h(-1) g(-1)) outperforming the disordered-In2O3-ZnIn2S4 counterpart (2700 mu mol h(-1) g(-1)) as well as many other state-of-the-art ZnIn2S4-based photocatalysts. The ordered architecture significantly boosts the short-range electron transfer in an In2O3-ZnIn2S4 heterojunction but has a negligible impact on the long-range electron transfer among In2O3 mesocrystals. The density functional theory (DFT) calculation reveals that the oriented etching is achieved by the selective binding of the [Co(CN)(6)](3-) etchant on the (110) plane of MIL-68(In), which can drag the In atoms out of the framework in order. Our findings could broaden the technical sense toward advanced photocatalyst design and impose scientific impacts on unveiling how ordered photosystems operate.

Abstract :

Unveiling the pore-size performance of metal organic frameworks (MOFs) is imperative for controllable design of sophisticated catalysts. Herein, UiO-66 with distinct macropores and mesopores were intentionally created and served as substrates to create advanced CdS/UiO-66 catalysts. The pore size impacted the spatial distribution of CdS nanoparticles (NPs): CdS tended to deposit on the external surface of mesoporous UiO-66, but spontaneously penetrated into the large cavity of macroporous UiO-66 nanocage. Normalized to unit amount of CdS, the photocatalytic reaction constant of macroporous CdS/UiO-66 over 4-nitroaniline reduction was similar to 3 folds of that of mesoporous counterpart, and outperformed many other reported state-of-art CdS-based catalysts. A confinement effect of CdS NPs within UiO-66 cage could respond for its high activity, which could shorten the electron-transport distance of NPs-MOFs-reactant, and protect the active CdS NPs from photocorrosion. The finding here provides a straightforward paradigm and mechanism to rationally fabricate advance NPs/ MOFs for diverse applications.

Abstract :

Nanoscale metal-organic frameworks (nano-MOFs) with unique open architectures offer great advantages for constructing fascinating functional materials, but their configurations are largely limited to mesoporous or hollow structures. Both the rational design of nano-MOFs with sophisticated structures and the comprehensive knowledge of their formation mechanism remain an interesting research topic. In this work, we reported a highly peculiar zigzag crystal of a Prussian blue analogue (PBA) bearing the ensemble of walls with uniform thickness (similar to 60 nm) in three-dimensional space. Such "Z"-like PBA was acquired by the preferential etching of two opposing corners of its parent NiCo-PBA cubes that was pre-doped by metal ligand ions (i. e., [Fe(CN)(6)](3-)). Mechanistic studies suggested that the anisotropic etching seemed to arise from the heterogeneous growth and inhomogeneous spatial distribution of the FeIII and FeII (stemming from redox reaction of FeIII) species, even though all the metal elements (including Fe, Co, and Ni) were evenly dispersed in each individual cube as indicated by HAADF-STEM and linear EDS scan analyses. The open "Z" structure provided larger surface area and a greater number of active sites to activate reagents in catalytic reaction and enhanced the degradation efficiency in removing bisphenol A from aqueous solution with PMS. The current findings are expected to pave way for a fine tuning the structures and properties of MOFs, and encourage extended research on developing novel anisotropic crystals.

Abstract :

Hollow metal-organic frameworks (MOFs) are of considerable research interest, but they usually contain only a single chemical component, and their spherical or randomly distributed voids may not have ideal properties. In this work, we found that incorporating WO42- ions into UiO-66 could realize a fine caving of the single crystals, which created W/UiO-66 nanocages with an uncommon and well-defined channel structure. Inspiringly, the width of the channel could be tuned on the nanoscale (80-140 nm) by varying the dose of WO42- in the etching reaction. Despite the accommodation of abundant W, the as-formed nanocages were of high crystallinity, which was confirmed by HRTEM images collected using a K2IS direct-detection electron-counting camera. As a result, the channel structure, which was well preserved after annealing, and the incorporation of W endowed the calcined W/UiO-66 nanocages with highlyimproved activity in the oxygen reduction reaction (ORR). This synthetic strategy could also be applied to creating Mo-bearing UiO-66 nanocages, and may inspire the rational design of other intricate MOFs.

Abstract :

Core-shell MOF@MOF structures are good candidates for the design of diverse multifunctional materials with intriguing properties. Conventional seed-induced growth procedures to create MOF@MOF usually suffer from limitations including the unavoidable nucleation/growth of the shell MOF in solution and the inevitable agglomeration of seeds. For the first time, an ion-modulation (Fe3+ as the indicator) strategy is demonstrated to realize one-pot synthesis of monodisperse MOF@MOF composed of two distinct Prussian blue analogues (PBAs). It utilized a finite amount of Fe3+ to induce a partial phase transition and generate new PBA nanoparticles epitaxially growing on the original PBA core. The as-prepared PBA@PBA with a distinct morphology, readily tunable by controlling the dose of dopant ions, can serve as a template for the creation of PBA nanocages with uncommon and tunable shapes for efficient phenol scavenging. The findings here pave the way for the rational design of MOFs with high complexity, good structural flexibility, and desirable activity.

Abstract :

Hierarchical metals oxide nanostructure derived from annealing of metal-organic frameworks (MOFs) usually have large particle size and low specific surface area and, as a result their activities, become limited. In this work, we incorporated KMnO4 into Prussian blue (PB) microcubes and obtained Mn-doped alpha-Fe2O3 nanoboxes by annealing the complex. We found that KMnO4 stayed inside the pores of the PB framework and restricted the crystal growth of alpha-Fe2O3 during annealing. Consequently, the Mn-doped Fe2O3 nanoboxes have small particle size, large specific area (452 m(2)/g), and a significant amount of adsorbed oxygen in the form of OH- on the surface as determined by X-ray photoelectron spectroscopy. It could serve as an adsorbent to quickly remove the trace-level (40 mg/L) Pb2+ from water. Within 1 min, this nanoadsorbent (0.2 g/L) extracted >70% Pb2+ in the solution, and >91.6% in 15 min. Besides, it also selectively captures Pb2+ (40 mg/L) from a synthetic Pb/Zn mining wastewater containing Zn2+ (40 mg/L) and various kinds of interfering ions (Na+, K+, Mg2+, Ca2+, SO42, NO3-, Cl-). The maximizing capacity of Pb2+ reaches to 900 mg/g when treating concentrated Pb2+ solution (1g/L). The spent adsorbent could be easily retrieved from the solution by magnetic separation. We anticipate the findings here will help to inspire the design of other novel MOFs-derived nanomaterials.

Abstract :

In recent years, tungsten oxide (WO3) has attracted enormous attention owing to its unique structural and optical properties; nonetheless, slow charge transfer, sluggish kinetics of holes, and rapid electron-hole recombination markedly retard its wide-spread applications in photocatalysis. Herein, variable WO3 superstructures were constructed with their architectures finely tuned by organic acids, based on which hierarchical g-C3N4 enwrapped WO3 superstructures were constructed by an in situ self-assembly strategy. A collection of combined structural and morphological characterizations manifested that WO3 and g-C3N4 ingredients were intimately integrated forming well-defined photoredox systems. We found that these closely assembled g-C3N4/WO3 heterostructures exhibited highly efficient and versatile photoredox performances including photo-oxidation of diverse organic pollutants and selective photoreduction of a series of aromatic nitro compounds under visible light irradiation and remarkably outperformed their corresponding single WO3 and g-C3N4 counterparts by virtue of cooperative synergy. An elegant Z-scheme dominated photoredox catalytic mechanism was unambiguously determined by probing the in situ formed active species (e.g., hydroxyl radicals, superoxide radicals, and hydrogen peroxide) responsible for the significantly enhanced photoredox performances of g-C3N4/WO3 heterostructures. It is anticipated that our work could provide a straightforward paradigm to rationally fabricate WO3 superstructures and judiciously construct a large variety of Z-scheme based photocatalysts.

Abstract :

Utilizing biowaste shells (>95 wt% CaCO3) in chemical synthesis can both remediate environmental pollution and produce novel functional materials. Nonetheless, syntheses of nanomaterials from solid matter such as bio-shells are still rare. Herein, we for the first time reported the synthesis of a 0D/2D nanostructure, i.e., Ca(OH)(2) nanosheets decorated with Mn3O4 quantum dots, from bio-shells in a green manner. Specifically, eggshells were calcined to form porous CaO that inherited a hierarchical framework from the source shell. The shell-derived CaO was then stirred together with KMnO4 in anhydrous ethanol at room temperature to generate the 0D/2D Ca(OH)(2)/Mn3O4 nanostructure (denoted as the Mn-Ca composite), in which Mn3O4 quantum dots were evenly dispersed on thin Ca(OH)(2) nanosheets. Mechanism studies revealed that a trace amount of H2O released from the redox reaction between KMnO4 and ethanol regulated the slow hydrolysis and exfoliation of Ca(OH)(2) nanosheets from the CaO framework. At the same time, the redox reaction generated Mn3O4 quantum dots that were deposited in situ on the Ca(OH)(2) nanosheets, i.e., only where H2O was liberated and the hydrolysis of CaO took place. This mechanism allowed the uniform dispersion of Mn3O4 on the newly formed Ca(OH)(2) nanosheets. Thanks to its unique 0D/2D structure, this Mn-Ca composite could highly efficiently extract trace-level Pb(II) from synthetic wastewater and outperformed many other Mn-based nanomaterials prepared purely from chemical reagents. This 0D/2D Mn-Ca composite possessed a high capacity for Pb removal (up to 1580 mg g(-1) when the initial Pb(II) concentration was 1 g L-1), and it could also scavenge various other heavy metal ions such as Cu(II), Cd(II), Eu(III), Co(II), and Ag(I). Other biowaste shells such as oyster shells and clam shells also successfully produced a functional nanomaterial via the presented methodology. The current findings open a new way for biowaste recycling and may inspire the design of novel nanomaterials.
