Summary: Research on ruthenium-based molecular complexes as catalysts for light-driven water splitting shows promising results, with most studies focusing on homogeneous solutions. However, in order to develop devices for light-driven water splitting, catalysts need to be translated to metal-oxide surfaces, emphasizing the importance of research in this area.

Summary: In this study, RP modified TiO2 hollow spheres were used for solar-to-hydrogen conversion. The optimal hydrogen production rate was achieved with the TiO2@RP heterostructure under simulated solar light irradiation. The hollow sphere structure and RP light absorber extended light absorption ability, and the heterostructure induced interfacial charge migration facilitated photoinduced charge separation, resulting in enhanced photocatalytic hydrogen production performance.

Summary: This study investigated the plasmonic Au (1 wt%) catalysts on hydrothermally synthesized TiO2 nanorods. Different sizes of Au nanoparticles (Au NPs) on Au/TiO2 catalysts were obtained by adjusting the mixing duration and calcination parameters. The presence of localized surface plasmon resonance effect was observed in all UV-Vis diffuse reflectance spectra of the catalysts, regardless of the size of Au particles. The study also identified superoxide anion radicals (O2 & BULL;-) as the main reactive oxygen species responsible for the oxidation of bisphenol A (BPA) under visible-light illumination.

Summary: Heterogeneous photocatalysis was used for degradation and mineralization of erythromycin, with TiO2 and Sn-doped TiO2 catalysts prepared and compared for their catalytic activity. The results showed that the M3 catalyst exhibited the best performance due to the formation of a staggered gap for better charge separation, enhancing catalytic efficiency and mineralization.

Summary: Photocatalysis is an effective method for converting CO2 into valuable chemicals, but its practical application is limited by efficiency and stability. In this study, an interfacial control strategy was proposed to enhance the interaction between light-harvesting semiconductors and molecular active centers. By constructing self-assembled organic semiconductors with controlled surface architectures, excellent CO2 photoreduction performance was achieved with high selectivity, stability, and quantum yield. The optimized biphase interface played a dominant role in the synergy between homogeneous and heterogeneous photocatalysts. This study will contribute to the design of future artificial photosynthesis systems.

Summary: The study investigated the influence of pH on the photocatalytic partial oxidation of 4-methoxybenzyl alcohol (MBA) and vanillyl alcohol (VA) using different TiO2 photocatalysts. The results showed that tuning pH can significantly affect the selectivity and activity of photocatalytic processes. The reaction rate and product selectivity were found to strongly depend on TiO2 crystallinity and substrate type, with different responses observed for different substrates under different pH conditions.

Summary: In this study, composites based on activated carbon and titanium dioxide were synthesized and used as photocatalysts for the removal of phenol in seawater. The composites exhibited higher photocatalytic activity than commercial titanium dioxide under both UV and visible light. The presence of salts in seawater had little effect on the photocatalysis under UV light, but enhanced the process under visible light. The best composite removed 70 mg of phenol/gcat under UV-C light and 55 mg of phenol/gcat under visible light. These results suggest that the composites have potential application in the removal of organic compounds in seawater.

Summary: This research synthesized and characterized CdS-g-C3N4 nanocomposite for photocatalytic degradation of CTX antibiotic, achieving a maximum degradation rate of 92.55% under optimized conditions determined through RSM-CCD model. The efficient photocatalytic performance is attributed to the appropriate energy level alignment between CdS and g-C3N4, which enhances charge separation and degradation efficiency of CTX. The photocatalytic degradation process was well described by Langmuir-Hinshelwood's pseudo-first-order model with an apparent rate constant of 0.0336 min(-1).

Summary: Heterostructure semiconductors, such as the Ag3PO4/TNWs heterostructure studied in this research, have gained attention in the fields of energy, environment, and catalysis. The study successfully synthesized titanium dioxide nanowires (TNWs) using the hydrothermal method and coupled them with Ag3PO4 to enhance absorption capacity and prevent recombination of photo-generated electrons and holes. The Ag3PO4/TNWs heterostructures demonstrated better photocatalytic performance and reduced application costs compared to pure TNWs and Ag3PO4. The mechanism study revealed the effective role of holes and anion radical superoxides in the photocatalytic activity of the heterostructures.
