Summary: Dual cocatalysts consisting of Ag and transition metal oxide loaded on a CTO photocatalyst showed higher CO production rate and improved H2 evolution rate, indicating photocatalytic activity for both CO2 reduction and water splitting. Additionally, CTO photocatalysts with a single TMOx cocatalyst exhibited higher activities in H2 evolution and O2 evolution tests, suggesting an enhancement in water splitting photocatalytic activity by TMOx. On the other hand, the photocatalytic activity for water splitting was suppressed by the Ag cocatalyst.

Summary: This study demonstrated the use of atomically thin LHTO nanosheets as a photocatalyst for efficient and stable conversion of CO2 to CO, outperforming bulk LHTO. The enhanced performance of atomically thin LHTO nanosheets was attributed to more CO2 adsorption sites, faster electron transfer rate, and a more negative conduction band edge compared to bulk LHTO.

Summary: The properties of potassium hexatitanate (K2Ti6O13, KTO) photocatalyst and the deposited Ag cocatalyst have an influence on the photocatalytic reduction of carbon dioxide to carbon monoxide. The calcination temperature and crystallite size of the KTO sample are positively correlated with the photocatalytic activity. The state of the Ag cocatalyst is also influenced by the calcination temperature, thus affecting the properties of the catalyst. Therefore, the photocatalytic activity is determined by both the properties of the KTO sample and the deposited Ag cocatalyst.

Summary: Photocatalytic steam reforming of methane (PSRM) using potassium hexatitanate (K2Ti6O13, KTO) fine crystals as photocatalysts loaded with Rh cocatalyst was studied. It was found that a Rh/KTO fine crystal photocatalyst with a larger surface area exhibited the highest hydrogen production rate (up to 30 mu mol h-1) with high selectivity. Granulated crystals showed 2.1-2.6 times higher hydrogen production rate compared to the original powdery fine crystals, indicating the importance of physical contact between crystals for enhanced photocatalytic activity.
