Summary: The photoexcited charge separation efficiency is usually considered as the key factor for enhancing the photocatalytic activity of photocatalysts. However, the role of the interfacial affinity between photocatalysts and substrates is rarely studied systematically. In this study, nitrogen vacancy-modified polymeric carbon nitride porous nanotubes (PCNpts) were synthesized and showed significant improvements in surface area, wettability, photoabsorption, charge separation capability, and photocatalytic activity in water splitting. Interestingly, the photoactivity of PCNpts showed substrate-dependent variation in contaminant degradation compared with bulk PCN. It was found that the interfacial affinity between PCNpts/PCN and contaminants/H2O, rather than the photoabsorption and charge separation capability, dominated their photoactivity.

Summary: In this paper, Co, N-co-doped graphene modified thin mesoporous carbon nitride (Co-NG/TMCN) was synthesized through electrostatic adsorption treatment. Extensive characterization was used to explore the morphology, structures and optical properties of the as-prepared photocatalysts. The 10 wt % Co-NG/TMCN exhibited a high photocatalytic hydrogen evolution rate (2949 μmol g(-1)) within 4 h visible light irradiation, which was about 113 times higher than that of the pure TMCN (26 μmol g(-1)). Co-NG material with excellent electrical conductivity played a major role in accelerating charge transfer from TMCN material to cobalt atomic clusters, effectively improving the photo-catalytic hydrogen evolution performance of Co-NG/TMCN material. Therefore, a feasible approach for doping transition metal clusters to enhance photocatalytic activity was provided.

Summary: Solar energy-driven biomass refinery to produce high value-added chemicals is gaining attention, but precisely modulating the selective oxidation of biomass-derived platform chemical remains challenging. This study presents a theoretical investigation on the oxidation of 5-hydroxymethylfurfural (HMF) to 2,5-furandicarboxylic acid (FDCA) at the atomic and molecular level, revealing the oxidative reaction mechanism. Two oxidation pathways were identified, with the hydroxymethyl group of HMF and the aldehyde group of HMF being oxidized to form different intermediates and finally leading to FDCA. The findings of the oxidation processes of HMF are significant for further utilization and development of this compound.

Summary: The construction of Bi2O4 @SnS 2D/1D hierarchical heterojunction with excellent light harvesting ability has significantly enhanced the photocatalytic degradation of tetracycline under visible light. The degradation rate constant of tetracycline over Bi2O4@SnS was 3.3 and 10.6 times higher than that over Bi2O4 and SnS, respectively. The enhanced photocatalytic activity can be attributed to the successful construction of the heterojunction and the increased specific surface area and broadened visible-light absorption region.
