Summary: Photocatalytic water splitting is a feasible method to replace traditional energy. In this study, a high-performance catalyst (Ag-g-C3N4) was obtained by growing amorphous Ag nanoparticles in situ on g-C3N4 nanosheets through a hydrothermal process. The Ag-g-C3N4 catalyst exhibits excellent catalytic activity, which is attributed to the special interaction between Ag nanoparticles and g-C3N4. The hydrogen production rate of Ag-g-C3N4 is significantly higher than pure g-C3N4 and most previously reported catalysts loaded with Ag or Pt. Our work demonstrates the promising potential of Ag-g-C3N4 as a catalyst for utilizing solar energy.

Summary: The photon energy-dependent selectivity of photocatalytic CO2-to-CO conversion was demonstrated for the first time using CsPbBr3 nanocrystals and CsPbBr3/g-C3N4 nanoheterostructures. The surficial capping ligands of CsPbBr3 nanocrystals adsorbed CO2, leading to the conversion of CO2 to CO through carbene pathways. The type-II energy band structure at the heterojunction of CsPbBr3/g-C3N4 nanoheterostructures separated the charge carriers, enhancing the efficiency of photocatalytic CO2-to-CO conversion.

Summary: Element doping is an effective method for enhancing the photocatalytic performance of photocatalysts. This study utilized potassium sorbate as a new precursor to dope potassium ions into g-C3N4 during the calcination process, resulting in the formation of potassium-doped g-C3N4 (KCN). Through various characterization techniques and electrochemical measurements, it was found that potassium doping efficiently modified the band structure of g-C3N4, enhancing light absorption and conductivity, which accelerated charge transfer and photogenerated carrier separation. These findings demonstrate the potential of potassium incorporation in g-C3N4 for fabricating high-performance photocatalysts for organic pollutant removal.

Summary: A novel Z-scheme CdS/CeO2/g-C3N4 nanocomposite was synthesized by a solvothermal method and its photocatalytic activity for the degradation of phenol was evaluated. The nanocomposite exhibited remarkable photocatalytic activity with a degradation rate of 95 % in 180 min, surpassing that of pure CeO2 and CdS/CeO2. The enhanced photocatalytic ability is mainly attributed to the higher adsorption capacity of three-dimensional porous g-C3N4 and the three-dimensional space electric field formed by its complex with CdS and CeO2.

Summary: Dye-sensitized H2 evolution systems were constructed using Pt-loaded SrTiO3 and Ru(II) complex photosensitizers. The size of the Pt particles impacted the activity of the system depending on the strength of the electron donor. Larger Pt particles showed higher activity with a stronger electron donor, while smaller Pt particles showed higher activity with a weaker electron donor. The results suggest that the cocatalyst particle size affects the kinetics of electron injection and carrier separation processes.

Summary: In this study, a Bi6NbWO14Cl photocatalyst was synthesized using Rh(2)O(3) additives and its surface was modified with Rh species to improve its photocatalytic activity. The addition of an appropriate amount of Rh2O3 significantly enhanced the O-2 evolution rate on Bi6NbWO14Cl, likely due to enhanced charge transfer by metallic Rh nanoparticles. Surface modification with Rh species further enhanced the O-2 evolution rate, achieving an apparent quantum efficiency of 11% at 420 nm, the best reported performance for oxyhalides prepared by solid-state reactions. The roles of these Rh species in the enhanced photocatalytic activities were discussed.

Summary: Various hybrid systems of metal-complex photocatalysts and semiconductor materials have been developed for photocatalytic CO2 reduction using the Z-scheme mechanism. This study focused on the photocatalytic activity of RuRu/Al2O3 in CO2 reduction by varying the adsorption density of RuRu. Increasing the adsorption density of RuRu led to a decrease in the production of the main product, HCOOH, due to the formation of Ru polymers. The addition of mononuclear Ru(II)-complex photosensitizers improved the photocatalytic activity of RuRu by supplying electrons to suppress its decomposition.

Summary: The synthesis of cobalt phosphate (CoPi)-modified, nitrogen-doped TiO2 nanotube arrays (N-TNAs) for photoelectrochemical (PEC) oxygen evolution under visible light is reported. The N-TNAs exhibit enhanced visible-light activity due to nitrogen doping, but their performance is diminished by self-oxidation. However, CoPi/N-TNAs prepared under optimal conditions show improved photocurrent generation and sensitivity to long wavelength light. Stable oxygen evolution with high Faradaic efficiency is achieved using CoPi/N-TNA photoanodes under simulated sunlight for at least 2 hours.
