Abstract ：
Photocatalysts with abundant oxygen vacancies (OVs) exhibit enhanced activity for the direct oxidation of benzene to phenol with O2, owing to their superior O2 activation and charge separation properties. However, OVs on metal oxide surfaces such as WO3 are susceptible to healing by oxygen-containing reactants or intermediates, leading to their irreversible deactivation. Herein, we demonstrate that incorporating Mo into the WO3 lattice effectively lowers the energy barrier for OV formation, promoting the dynamic formation of more abundant photoinduced OVs in situ on the surface during the photocatalytic reaction. These Mo-promoted photoinduced OVs are found to ensure the long-term sustainability of sufficient OVs under working conditions, enhancing photocatalytic performance and particularly its durability in the aerobic oxidation of benzene to phenol. These findings provide a straightforward strategy to overcome the issue of OV healing, enabling the sustainable operation of OV-rich photocatalysts for a range of emerging applications, even in O2-involved redox reactions.

Abstract ：
Lead pollution presents a significant threat to ecological systems and human health, underscoring the urgent need for highly sensitive detection methods. Herein, we introduce a novel DNA concatemer-encoded CRISPR/Cas12a fluorescence sensor (MDD-Cas12a) for sensitive detection of Pb2+ based on DNAzymes. To accomplish this, we designed a substrate strand containing a long DNA concatemer encoding multiple protospacer adjacent motifs (PAMs) and protospacer sequences for activation of the CRISPR/Cas12a system. The DNA concatemer was subsequently anchored to the surface of magnetic beads (MBs) to fabricate a MBs-DNA concatemer nanoprobe. In the presence of Pb2+, the DNAzyme structure catalyzes the cleavage of the substrate strand, leading to the release of DNA concatemers. Following magnetic separation, the released DNA concatemers significantly activate the non-specific trans-cleavage activity of the Cas12a/crRNA complex. The fluorescence reporter DNA is then completely cleaved by the activated Cas12a/crRNA complex, and the Pb2+ concentration in the sample can be quantified by measuring the fluorescence signal. By harnessing the specific recognition capability of DNAzymes for Pb2+, the programmability of DNA concatemers, and the self-amplification features of the CRISPR/Cas12a system, the MDD-Cas12a platform demonstrates high sensitivity and specificity for detecting Pb2+ in milk and lake water samples.

Abstract ：
Creating useful chemicals or fuels from CO2 is one of the most promising ways to reach carbon neutral. In this work, through the formation of Lewis acid sites, a string of boron-atom-coordinated Ru single-atom catalysts (SACs), namely RuBxN4-x@TiN (x=0–4), were constructed, and their CO2 reduction reaction (CO2RR) was systematically studied. The results show that o-RuB2N2@TiN, p-RuB2N2@TiN, and RuB3N1@TiN are able to efficiently inhibit the competitive hydrogen evolution reaction (HER) and activate CO2, with a potential-determining step lower than 0.7 eV and high selectivity for CH4 generation. This work shows that the synergistic effect of B and Ru atoms are able to effectively improve the catalytic activity, which is expected to offer a possible tactic for the sensible creation of effective CO2RR catalysts. © 2024

Abstract ：
Electrocatalytic semi-hydrogenation of acetylene to ethylene has recently attracted attention as a process for removing acetylene from ethylene-rich gas streams due to its mild conditions and energy-saving advantages. However, developing catalysts with low cost and high selectivity for acetylene semi-hydrogenation remains a huge challenge. Here, we investigated the effect of hydroxyl group modification on the acetylene semi-hydrogenation selectivity of poly(heptazine imide) (PHI) supported metal single atom catalyst under alkaline conditions by density functional theory calculations. The results show that hydroxyl group as ligand not only increases the steric resistance of acetylene adsorption, but also acts as electron-withdrawing group to delocalize the electrons of metal atoms, weaken the interaction with acetylene and subsequent intermediates, and make the adsorption moderate, which is beneficial to the desorption of ethylene and avoid over-hydrogenation. The Ni-OH/PHI and Fe-2OH/PHI are capable of achieving the selective hydrogenation of acetylene to ethylene and have good thermodynamic stability, which can be used as ideal catalysts for the electrocatalytic semi-hydrogenation of acetylene to selectively generate ethylene. This study provides theoretical guidance for the rational design of electrocatalysts for the selective semi-hydrogenation of acetylene. © 2024 Elsevier B.V.

Abstract ：
Photocatalytic CO2 conversion to industrial fuels is considered an effective measure to solve energy and environmental problems. Presently, Catalysts for CO2 reduction reaction (CO2RR) are mostly confined to metal-based materials, but non-metal materials are less explored. We decorate the highly crystalline carbon nitride, i.e., poly(triazine) imides (PTI), with non-metallic boron (B) to obtain two B/PTI catalysts: Bi/PTI with B being deposited into the six-fold cavity of the PTI, and Bs/PTI with B substituting for C in PTI. For CO2RR, Bi/PTI follows a quasi Mars-van Krevelen process, but the high exposure of Bi results in an overly strong interaction with intermediates, inhibiting the reactivity. In contrast, Bs/PTI enhances the binding with intermediates by introducing Lewis acid-base pairs (B-N), which reduce the ring conjugation effect and induce the enrichment of electrons at the pyridine N. Hence, CO2 reduction with the adsorbed H* (Ha) hydrogenation mechanism in Bs/PTI has a significant reactivity. © 2024 Elsevier B.V.

Abstract ：
Development of earth-abundant, low-cost and easily synthesizable catalysts for the semi-hydrogenation of acetylene is urgently needed. Here, we have systematically investigated the structure, electronic properties, hydrogen dissociation, and acetylene semi-hydrogenation activity and selectivity of poly(heptazine imide) (PHI) loaded with different sizes of Cun (n = 1,2,4,13) clusters (Cun/PHI) by density functional theory calculations. The results show that Cu4/PHI with tetrahedral configuration has a better hydrogenation activity in the acetylene semi-hydrogenation reaction with H adsorbed in the vicinity of acetylene and subsequent intermediates in a non-bridge position, resulting in a smaller hydrogenation energy barrier. In addition, the top Cu atom transfers a large number of electrons to the bottom Cu atoms and PHI, and only a small number of electrons transfer to ethylene, resulting in weak adsorption of ethylene and easy desorption, which makes it good selectivity and therefore it can be used as a candidate catalyst for the semi-hydrogenation of acetylene. This study provides insights into the design of catalysts with suitable size clusters loaded on carbon nitride materials for efficient acetylene semi-hydrogenation reactions. © 2024 Elsevier B.V.

Abstract ：
Amorphous Ga2O3 thin films were deposited on SiO2 and sapphire substrates by pulsed magnetron sputtering (PSD) at room temperature, respectively. Corresponding amorphous Ga2O3 thin film photodetectors were prepared. The oxygen vacancies and defects of the interface between films and substrates were found to determine the discrepancy by comparing the performance between these two photodetectors. Amorphous Ga2O3 photodetectors on SiO2 had highly performances with a responsivity of 417 A/W, detectivity of 7.84 x 1012 Jones, and external quantum efficiency of 2.01 x 105 %.

Abstract ：
Defect engineering has been widely applied in semiconductors to improve photocatalytic properties by altering the surface structures. This study is about the transformation of inactive WO 3 nanosheets to a highly effective CO 2 - to - CH 4 conversion photocatalyst by introducing surface - ordered defects in abundance. The nonstoichiometric WO 3 - x samples were examined by using aberration - corrected electron microscopy. Results unveil abundant surface - ordered terminations derived from the periodic {013} stacking faults with a defect density of 20.2%. The {002} surface - ordered line defects are the active sites for fixation CO 2 , transforming the inactive WO 3 nanosheets into a highly active catalyst (CH 4 : O 2 = 8.2: 16.7 mu mol h -1 ). We believe that the formation of the W - O - C - W - O species is a critical step in the catalytic pathways. This work provides an atomic - level comprehension of the structural defects of catalysts for activating small molecules.

Abstract ：
Cadmium sulfide (CdS) exhibits remarkable light absorption capabilities and is widely employed in photocatalytic reduction of CO2. Nevertheless, the crystal facet effects on the micro-scale mechanisms governing CO2 conversion on CdS remain elusive. This study theoretically investigates the electronic properties of hexagonal-phase (101), (001), and cubic-phase (111) CdS surfaces modified with diethylenetriamine (DETA). From a microscopic viewpoint, it elucidates the unique bonding characteristics of CO2 on different exposed facets of DETA/CdS and the formation mechanisms leading to products such as CO, HCOOH, CH2O, CH3OH, and CH4. Our findings reveal that the DETA/CdS(101) surface is the most stable, effectively adsorbing hydrogen and CO2 at varied Cd sites with a high selectivity towards CO production, thereby showing promise for syngas generation, albeit with potential yields of formic acid and methane. Conversely, DETA/CdS(001) and (111) primarily facilitate the reduction of CO2 to CH4. These discoveries offer theoretical insights into photochemical experiments involving CO2 reduction on CdS, shedding light on the influence of crystal facets on reaction pathways.
