Abstract :
This study reported the preparation of a visible-light-responsive polymer carbon nitride carbonized coating (VLPCNC) using gamma-C2S and photo-responsive polymer carbon nitride (PCN), primarily designed for air purification. The effects of varying PCN content on the photocatalytic properties, bonding strength, and erosion resistance of VLPCNC were investigated, with the mechanism analyzed through a series of microscopic techniques. Results demonstrated that VLPCNC with PCN displayed excellent photocatalytic efficiency under visible light. A rise in PCN content from 10 % to 50 % led to a substantial enhancement in the NO removal rate, increasing from 287.5 mu mol center dot m-2 center dot h-1 (14.7 %) to 720.9 mu mol center dot m-2 center dot h-1 (44.1 %). Incorporating 10 % of PCN could improve the bond strength of VLPCNC with concrete substrate. PCN could act as nucleation sites that enhance the carbonation of gamma-C2S, thus improving the bonding. However, a high PCN content significantly weakened the bond, as the dilution effect lowered the concentration of carbonation products in the binder. The NO removal performance of VLPCNC with 10 % PCN only reduced by 5.8 % after 1 d scouring treatment and the reduction increased when PCN content increased. All of the VLPCNC could remain good photocatalytic properties after 7 d scouring. The PCN particles were partially encapsulated by calcium carbonate crystals and adhered to their surface, enhancing the anti-scouring performance of VLPCNC. Notably, VLPCNC-10 exhibited a balance of exceptional photocatalytic properties, mechanical strength, and durability.

Abstract :
Photocatalysis technology holds great potential in converting CO2 into value-added chemicals and fuels, playing a significant role in achieving carbon neutrality and promoting carbon cycling. However, the low charge carrier separation efficiency of existing photocatalysts limits their performance in CO2 utilization. Herein, a novel Sscheme structured 2D/2D WO3/InVO4 composite is successfully synthesized via hydrothermal method, which maintains the high selectivity for converting CO2 to CO under visible light without the need for noble metal cocatalysts or sacrificial agents. The optimized WO3/InVO4 composite exhibits CO yields of 13.37 mu mol/g, which is 3.36 times higher than that of InVO4. Enhancement in photocatalytic performance is primarily attributed to the meticulously designed S-scheme heterojunction structure, which effectively achieves spatial separation of photogenerated charges. Furthermore, the intimate contact between 2D WO3 and 2D InVO4 enhances charge transfer efficiency. This work offers valuable insights for the design and construction of novel S-scheme heterojunction photocatalysts.

Abstract :
Mimicking photosynthesis to convert CO2 and H2O into value-added chemicals represents an optimal approach to mitigate energy shortages and environmental pollution, and the development of highly efficient and selective photocatalysts for CO2 to CO conversion is essential for the effective utilization of CO2 resources. Herein, a novel 2D@0D InVO4@MnWO4 S-scheme heterojunction composite is successfully developed via an in situ hydrothermal method, achieving the conversion of CO2 into CO under visible light irradiation using H2O as a reducing agent, without any noble metal cocatalysts or sacrificial reagents. The CO generation rate over the optimal InVO4@MnWO4 composite reaches 6.20 mu mol g-1 h-1, which is approximately 4.50 times than that of InVO4. The enhanced photocatalytic performance is ascribed to the charge separation facilitated by the formation of an S-scheme heterojunction between InVO4 and MnWO4. This work is expected to provide a new insight for the design of highly selective photocatalysts for the conversion of CO2 to CO.

Abstract :
Employing photocatalytic technology to transform CO2 into valuable fuels is considered a promising solution for addressing the exacerbated greenhouse effect and energy crisis. The development of photocatalysts featuring superior charge separation efficiency is pivotal for the widespread implementation of photocatalytic CO2 reduction technologies. Herein, zero-dimensional (0D) NixP nanoparticles are anchored onto two-dimensional (2D) LaTiO2N nanosheets by a photo-deposition method, and a NixP/LaTiO2N Schottky junction composite with excellent photocatalytic CO2 reduction performance is constructed. The optimal NixP/LaTiO2N composite achieves CO and CH4 yields of 9.39 and 4.15 mu mol g-1 h-1, respectively, with the utilized photoelectron number (UPN) reaching 51.98 mu mol g-1, which is approximately 9.7 times higher than that of LaTiO2N alone. The improved photocatalytic performance of the composites can be attributed to the formation of Schottky junctions, which effectively suppress the recombination of photogenerated carriers. This study provides a new idea for the development of 0D/2D Schottky junction photocatalysts.

Abstract :
Photocatalytic water splitting represents a promising approach for solar energy conversion and hydrogen production. Polymeric carbon nitride (PCN) exhibits potential but suffers from charge recombination and low specific surface area. This study introduces a novel LaOBr@PCN one-photon excited heterojunction designed to mitigate these challenges. By anchoring Melon, a PCN precursor, onto LaOBr through acid-base coordination followed by in-situ thermal polymerization, three-dimensional hierarchical PCN nanosheets are fabricated on LaOBr microplates. This structure increases the specific surface area, exposes more active sites, enhances lightharvesting ability, and improves charge carrier separation. Consequently, the optimized LaOBr@PCN achieves hydrogen and oxygen production rates of 69.9 mu mol/h and 34.7 mu mol/h, respectively. This work provides a viable strategy for developing advanced PCN-based composite photocatalysts.

Abstract :
Solar-powered photocatalytic water splitting for hydrogen evolution presents a promising solution to the energy crisis and contemporary environmental challenges. Herein, a Z-scheme ZnS/LaTiO2N heterojunction composite, incorporating zinc vacancies, has been successfully synthesized to enable photocatalytic hydrogen evolution under visible-light illumination. The optimized ZnS(VZn)/LaTiO2N composite demonstrates a hydrogen evolution activity 13 times higher than that of individual ZnS(VZn). The heterojunction between ZnS and LaTiO2N, in conjunction with zinc vacancies, expands the photoresponse spectrum and facilitates the spatial separation and transfer of photogenerated carriers. Consequently, this synergy significantly enhances the performance of photocatalytic hydrogen evolution. The collaborative action of the Z-scheme heterojunction and zinc vacancies paves the way for innovative approaches in designing future high-efficiency photocatalysts.

Abstract :
The photocatalytic conversion of CO2 into hydrocarbon fuel holds immense potential for achieving a carbon closed loop and carbon neutrality. Developing efficient photocatalysts plays a pivotal role in enabling the widespread application of photocatalytic CO2 reduction on a large scale. Herein, a novel S-scheme MnWO4/LaTiO2N heterojunction composite is successfully synthesized by a hydrothermal method. This composite catalyst demonstrates excellent photocatalytic activity in the reduction of CO2 to CO and CH4 using water molecules as electron donors under visible light irradiation, and the optimized 30% MnWO4/LaTiO2N composite displays significantly enhanced CO and CH4 yields of 3.94 and 0.81 mu mol g(-1) h(-1), respectively, and the corresponding utilized photoelectron number reaches 14.7 mu mol g(-1) h(-1), which is approximately 7.7 and 12.9 times that of LaTiO2N and MnWO4. The enhancement in photocatalytic activity of the composites can be ascribed to the construction of an S-scheme heterojunction, which exhibits improved charge transfer dynamics, retains the strongest redox capacity, and effectively suppresses back reactions. In situ Fourier-transform infrared imaging provides evidence, to a certain extent, for the existence of a temporal gradient order in the generation of multiple products during the photocatalytic reduction of CO2.

Abstract :
The interaction of low energy electrons (LEEs; 1-30 eV) with genomic material can induce multiple types of damage that may cause the loss of genetic information, mutations, genome instability, and cell death. For all damages measurable by electrophoresis, we provide the first complete set of G-values (yield of a specific product per energy deposited) induced in plasmid DNA by the direct and indirect effects of LEEs (G LEE) and 1.5 keV X-rays (G X) under identical conditions. Low energy photoelectrons are produced via X-rays incident on a tantalum (Ta) substrate covered with DNA and placed in a chamber filled with nitrogen at atmospheric pressure, under four different humidity levels, ranging from dry conditions to full hydration (Gamma = 2.5 to Gamma = 33, where Gamma is the number of water molecules/nucleotide). Damage yields are measured as a function of X-ray fluence and humidity. G LEE values are between 2 and 27 times larger than those for X-rays. At Gamma = 2.5 and 33, G LEE values for double strand breaks are 27 and 16 times larger than G X, respectively. The indirect effect contributes similar to 50% to the total damage. These G-values allow quantification of potentially lethal lesions composed of strand breaks and/or base damages in the presence of varying amounts of water, i.e., closer to cellular conditions.

Abstract :
Using solar-powered photocatalytic technology to convert CO2 to high value-added chemical products is a hopeful strategy to solve the energy and environmental problems of modern society. Herein, a direct Z-scheme InVO4/La2Ti2O7 photocatalyst is successfully synthesized, achieving efficient and selective CO2 re-duction to CO with nearly 100 % CO selectivity, and the CO yield is 4.2 and 3.3 times that of individual La2Ti2O7 and InVO4, respectively. The significantly enhanced photocatalytic performance is owing to the formation of Z-scheme charge transfer mechanism, fostering the spatial separation and transfer of pho-togenerated carriers. This work provides new perspectives for the rational design of La2Ti2O7-based pho-tocatalytic materials toward efficient and selective CO2 reduction to CO. (c) 2022 Elsevier B.V. All rights reserved.
