Summary: The photocatalytic CO2 reduction reaction is a sustainable route to convert greenhouse gases into chemicals. Inorganic photocatalysts, like titanium dioxide (TiO2), have been extensively studied due to their stability and low cost. However, a more efficient TiO2 photocatalyst without noble metals is desired for CO2 reduction. In this study, a novel strategy of anchoring a single tungsten (W) atom site with oxygen-coordination at the intrinsic steps of TiO2 nanoparticles is developed. This strategy allows for the control of active sites composition, resulting in significantly improved CO2 reduction efficiency and methane selectivity.

Summary: The advent of Z-scheme heterojunction has significantly improved the CO2 photoreduction efficiency of photocatalysts, but the construction of heterojunction and study of photocatalytic mechanism remain challenging. In this study, a Z-scheme heterojunction photocatalyst (BP:La/InVO4:La) based on a single atom of La anchored on black phosphorus was successfully constructed, achieving approximately 100% CO selectivity for CO2 reduction. The CO generation rate of BP:La/5-InVO4:La was approximately 7.9 and 4.9 times higher than that of black phosphorus and InVO4, respectively. X-ray photoelectron spectroscopy, photoluminescence, and density functional theory analysis confirmed that BP:La/InVO4:La is a Z-scheme heterojunction, with the La single atom playing multiple roles in regulating surface active sites, promoting CO2 absorption, and increasing O defects to improve photocatalytic performance. The enhanced selectivity of the Z-scheme heterojunction was further demonstrated by calculating the rate-determining steps and selectivity-determining steps. This study provides unique insights for the rational design of rare earth composite photocatalysts.

Summary: Single-atom active-site catalysts have attracted significant attention in the field of photocatalytic CO2 conversion. However, designing active sites for CO2 reduction and H2O oxidation simultaneously on a photocatalyst and combining the corresponding half-reaction in a photocatalytic system is still difficult. In this study, a bimetallic single-atom active-site photocatalyst with two compatible active centers of Mn and Co was synthesized. The active center of Mn promotes H2O oxidation by accumulating photogenerated holes, while the active center of Co enhances CO2 activation by modifying the bond length and bond angle of CO2 molecules. The synthesized Mn1Co1/CN catalyst exhibited a significantly higher CO production rate compared to the corresponding single-metal active-site photocatalyst due to the synergistic effect of the atomic active centers.
