Abstract ：
ZnIn2S4 has been extensively studied in the field of photocatalytic hydrogen evolution (PHE), but its bulky structure often results in high charge carrier recombination and low light harvesting capability. Herein, efficient hierarchical MGa2O4/ZnIn2S4 (M = Ni, Co) hollow nanofiber photocatalysts with p-n heterojunction were fabricated by an electrospinning-solvothermal method. The hierarchical structure of MGa2O4/ZnIn2S4 composites has facilitated p-n heterojunction formation, promoted the charge separation efficiency, enhanced light harvesting capability, and provided abundant reactive sites. The synergistic effects of MGa2O4 and ZnIn2S4 accelerated the PHE rate by reducing the *H reaction intermediates energy barrier. Under simulated solar light, the NiGa2O4/ZnIn2S4 and CoGa2O4/ZnIn2S4 with optimal proportions delivered outstanding PHE rate of 9292 and 6283 µmol·g−1·h−1, which was 5 and 3 times higher than that of pure ZnIn2S4, respectively. This work opens up an efficient electrospinning-mediated solvothermal strategy for constructing hierarchical ZnIn2S4-based nanofiber composites with excellent PHE performance. © 2024 Elsevier Ltd

Abstract ：
Constructing novel surface microstructures for photocatalytic materials could significantly enhance the photocatalytic hydrogen production rate from water splitting. In this work, novel 2D/3D structured CuCo2S4/CdIn2S4 p-n heterojunction photocatalysts for water splitting were successfully prepared by a solvothermal method. The coupling of a 2D CuCo2S4 nanoplate on the surface of 3D flower-like CdIn2S4 microspheres has strengthened the visible light absorption and promoted the charge separation efficiency due to their tight contacting area. The obtained CuCo2S4/CdIn2S4 (CSCIS-2) photocatalyst exhibited a hydrogen production rate of 1320 mu mol g(-1) h(-1), which was fivefold of that for pure CdIn2S4. Additionally, cyclic tests demonstrated improved photoactivity stability of the samples. A series of photoelectrochemical characterizations confirmed the effective suppression of charge carrier recombination in CuCo2S4/CdIn2S4 composite catalysts. Finally, a rational photocatalytic mechanism was proposed based on the semiconductor band theory. This work contributes to the enrichment of sulfide-based research and applications in photocatalysis.

Abstract ：
Photocatalytic organic synthesis has attracted much attention in recent years. Herein, a N and C co-decorated mesoporous TiO2 (mp-NCT) photocatalyst was synthesized for selective oxidation of alcohols. Notably, the as-prepared mp-NCT composites possess large specific surface areas and mesoporous structures, which could provide sufficient active sites and improve mass transfer. Furthermore, the co-doping of N and C species could not only extend the light absorption, but also tune the valence band of TiO2. Meanwhile, numerous oxygen vacancies and intra-band could be introduced, which helps to reduce the combination of the photogenerated carriers. As a result, the mp-NCT composites show excellent photocatalytic performance towards selective oxidation of benzyl alcohol and its derivatives to corresponding aldehydes under simulated sunlight irradiation. Mechanism studies revealed that the photogenerated electrons, holes and high dynamic equilibrium concentration of O2•- radicals were responsible for the efficient conversion of alcohols to aldehydes. © 2024

Abstract ：
Chemoradiation therapy (CRT), which combines a chemotherapeutic drug with ionizing radiation (IR), is the most common cancer treatment. At the molecular level, the binding of Pt-drugs to DNA sensitizes cancer cells to IR, mostly by increasing the damage induced by secondary low-energy (0-20 eV) electrons (LEEs). We investigate such enhancements by binding terpyridine-platinum (Tpy-Pt) to supercoiled plasmid DNA. Fifteen nanometer thick films of Tpy-Pt-DNA complexes in a molar ratio of 5 : 1 were irradiated with monoenergetic electrons of 5 and 10 eV, which principally attach to the DNA bases to form transient anions (TAs) decaying into a multitude of bond-breaking channels. At both energies, the effective yields of crosslinks (CLs), base damage (BD) related CLs, single and double strand breaks (SSBs and DSBs), non-DSB-cluster lesions, loss of supercoiled configuration and base lesions are 6.5 +/- 1.5, 8.8 +/- 3.0, 88 +/- 11, 5.3 +/- 1.3, 9.6 +/- 2.2, 106 +/- 17, 189 +/- 31 x 10(-15) per electron per molecule, and 11.9 +/- 2.6, 19.9 +/- 4.4, 128 +/- 18, 7.7 +/- 3.0, 13.4 +/- 3.9, 144 +/- 19, 229 +/- 42 x 10(-15) per electron per molecule, respectively. DNA damage increased 1.2-4.2-fold due to Tpy-Pt, the highest being for BD-related CLs. These enhancements are slightly higher than those obtained by the conventional Pt-drugs cisplatin, carboplatin and oxaliplatin, apart from BD-related CLs, which are about 3 times higher. Enhancements are related to the strong perturbation of the DNA helix by Tpy-Pt, its high dipole moment and its favorable binding to guanine (G), all of which increase bond-breaking via TA formation. In CRT, Tpy-Pt could considerably enhance crosslinking within genomic DNA and between DNA and other components of the nucleus, causing roadblocks to replication and transcription, particularly within telomeres, where it binds preferentially within G-quadruplexes.

Abstract ：
针对室内低浓度甲醛（～0.2 mg/m~3）的净化处理，选择两种不同孔径分布的活性炭，通过红外光谱（FT-IR）、比表面积及孔径（BET）测试和扫描电镜（SEM）分析，两种活性炭为同材质炭，孔容占比分别为：中孔炭（A）的微孔容积占比为9%(V_(Micro)/V_(Total)），中孔容积占比为91%(V_(Medium)/V_(Total)）；中微孔炭（B）的微孔容积占比为72%(V_(Micro)/V_(Total)），中孔容积占比为28%(V_(Medium)/V_(Total)）。利用静态法评价装置对活性炭样品吸附低浓度甲醛性能进行测试。结果表明，湿度变化对活性炭吸附低浓度甲醛基本没有影响；小范围的温度变化对不同孔径活性炭的吸附速率有较大影响；多次注入低浓度甲醛的测试表明，中微孔炭的吸附容量要显著高于中孔炭；甲醛脱附测试表明，中微孔炭的脱附量远小于中孔炭，对比两种活性炭的孔容，可以认为，微孔孔容有助于低浓度甲醛的吸附和锁定。

Abstract ：
Histone proteins protect cellular DNA from radiationdamage. Wefind that arginine, a major component of histone proteins, protectsDNA from lesions induced by low-energy secondary electrons generatedby radiation. Thin films of 7 +/- 2, 12 +/- 4, and 17 +/- 4 nm thicknesses containing arginine-plasmid-DNA complexesin molar ratio of [Arg(2+)]/[PO4 (-)] = 16 are irradiated in vacuum with 5 and 10 eV electrons. Damageyields are measured for base damages, cross-links, single-strand breaks(SSBs), double-strand breaks, and other clustered lesions. Most damageresults from dissociative electron attachment. Absolute cross sections(ACSs) for all damage types are extracted from yields at differentfilm thicknesses. Compared with bare DNA, these ACSs are reduced byfactors of up to 4.4 in Arg-DNA complexes. SSB protection isthe highest. Potentially lethal cluster lesions decrease by factorsof up to 2.2. ACSs are critical input parameters in modeling radiation-induceddamage and assessing protection factors under simulated cellular conditions.

Abstract ：
Constructing heterojunction is an efficient strategy to boost the charge carrier separation rate and promote the catalytic performance for photocatalysts. In this paper, amorphous CoMoS4 was first deposited on the surface of the flower-like microspheres of CdIn2S4 to fabricate CoMoS4/CdIn2S4 composites for accelerating the photocatalytic hydrogen evolution (PHE) rate under simulated sunlight irradiation. The compositions, morphologies, and photoelectrochemical properties of the obtained samples were examined. SEM images show that a great number of CoMoS4 nanoparticles were filled into the gaps of CdIn2S4 microspheres. Optical characterization shows that the combination of CoMoS4 and CdIn2S4 strongly strengthened their light absorption capability. The remarkably promoted PHE rate of the optimum 5%-CCIS catalyst (2196 mmol g-1 h-1) was 8.4 folds larger than that for CdIn2S4. More importantly, the heterostructured 5%-CCIS composite also exhibited good activity stability in the three-cycled experiments. Photoelectrochemical measurements provided the energy band potentials and demonstrated the efficient charge separation efficiency, consistent with the photocatalytic activity of CoMoS4/CdIn2S4 composites for hydrogen production. This study will provide a new strategy to fabricate CoMoS4-based heterostructures for boosting the hydrogen evolution under visible light.(c) 2023 Hydrogen Energy Publications LLC.

Abstract ：
Constructing heterojunctions with transition metal sulfides is an excellent strategy to reduce the dependency on noble metals in photocatalytic water splitting. Herein, 0D CoMoS4 nanoparticles were first deposited in-situ on the surface of 3D ZnIn2S4 microflowers for constructing heterostructured CoMoS4-ZnIn2S4 (CMS-ZIS) compos-ites. The CMS-ZIS composites showed strengthened absorption capabilities in the visible light region compared with pure ZnIn2S4. The electron microscopy scanning images indicate that countless CoMoS4 particles were loaded into the gaps on the surface of ZnIn2S4 microflowers, resulting in a close interface contact between the materials. The photocatalytic hydrogen evolution (PHE) rate of the optimized CMS-ZIS-3 product is 6.43 folds that of pure ZnIn2S4, which is approximately 3942.1 mu mol g(-1) h(-1). The enhanced activity should be attributed to the promoted carrier transfer rate and reduced recombination efficiency. We inferred the possible mechanism for photocatalytic hydrogen production over CMS-ZIS-3 based on the band potential and photoelectrochemical testing results. This study provides a feasible strategy for designing efficient and cost-effective 0D/3D heterostructures.

Abstract ：
Z-scheme photocatalysts commonly possess both high charge separation efficiency and strong redox ability. In this paper, novel 3-dimensional/2-dimensional (3D/2D) structured bismuth-rich bismuth oxide iodide/bismuth oxide bromide (Bi4O5I2/BiOBr) hybrids with Z-scheme heterojunctions were first prepared. The in situ generated I-3(-)/I- and Bi5+/Bi3+ redox mediators in Bi4O5I2/BiOBr hybrids greatly improve their photocatalytic activity toward phenolic contaminants. Their structure, morphology, optical properties, and electrochemical properties were characterized. Scanning electron microscopy images demonstrated that the 2D BiOBr nanoplates were evenly and tightly anchored on the surface of the 3D Bi4O5I2 microspheres. This novel 3D/2D spatial structure was beneficial for the formation of heterojunctions between BiOBr and Bi4O5I2, which improved the quantum efficiency through interfacial charge transfer. The Bi4O5I2/BiOBr hybrids exhibited excellent photocatalytic activities toward o-phenylphenol (OPP), p-tert-butylphenol, 4-chlorophenol, and p-nitrophenol. Bi4O5I2/BiOBr-5 possessed the best activity in decomposing OPP, which was approximately 3.43 times higher than that of pure Bi4O5I2. The well-matched energy bands of components in the hybrids facilitated the interfacial charge separation through an effective Z-scheme transfer direction guided by I-3(-)/I- and Bi5+/Bi3+ redox mediators. Based on the results of electron spin paramagnetic resonance and trapping experiments, a mechanism was proposed for the degradation of pollutants using the Bi4O5I2/BiOBr hybrids.
