Summary: To improve the utilization efficiency of noble metals as co-catalysts, Pt atoms are dispersed on S-doped g-C3N4 nanotubes through in situ pyrolysis of H2PtCl6. The Pt atoms are anchored by coordination with diatomic N and S of g-C3N4, resulting in a high dispersion and stabilization. The optimized H2 production rate and turnover frequency are significantly higher compared to Pt nanoparticle loaded g-C3N4 nanotube. This work provides a new approach to anchor noble metal on photocatalyst and enhance atomic utilization efficiency.

Summary: This study focused on optimizing the synthesis method of g-C3N4 through changing the polymerization temperature, showing that full formation of graphitic carbon nitride requires a temperature above 550 degrees C. Precursors and heating rate were found to have a significant influence on the photocatalytic activities, with higher activities achieved at a lower heating rate.

Summary: Understanding the metal-support interactions is crucial to develop a highly efficient Pt/g-C3N4 photocatalyst for the H2 evolution reaction. PtO species are formed via specific chemical bonding between Pt and O-containing functional groups, resulting in highly dispersed PtO species on SCN. The optimized Pt content and distribution over SCN showed the highest HER activity and charge separation efficiency, significantly enhancing the photocatalytic performance.

Summary: A novel highly dispersed NH2-MIL-101(Fe)/carboxylated g-C3N4 heterostructure was prepared using a facile oil bath method. The chemical bonding interaction promoted the heterogeneous nucleation and growth, resulting in nanometer-sized granular morphology of NM-101(Fe) uniformly dispersed on CCN surface. The 10% NM-101(Fe)/CCN heterostructure exhibited high removal efficiency for Cr(VI) and ciprofloxacin (CIP) pollutants.

Summary: In this study, highly dispersed P-doped CNS with a trimetallic phosphide CoNiFeP cocatalyst was successfully fabricated for photocatalytic hydrogen evolution. Compared with the traditional preparation method, the synthesized cocatalyst exhibited no aggregation and high dispersibility. The results showed that this cocatalyst could effectively promote the separation of photogenerated electron-hole pairs and accelerate the migration of carriers. The maximum hydrogen evolution rate of the cocatalyst was approximately four times higher than that of pure CNS-Pt when using TEOA solution as a sacrificial agent. The cocatalyst also demonstrated good stability during the photocatalytic reaction.
