BaTi 4 O 9 Photocatalysts with Variously Loaded Ag Cocatalyst for Highly Selective Photocatalytic CO 2 Reduction with Water

摘要: Photocatalytic reduction of CO2 with water to valuable chemicals has been getting attention as an artificial photosynthetic system using CO2 as a resource. A barium tetratitanate, BaTi4O9, loaded with Ag nanoparticles (Ag/BaTi4O9) successfully promoted the photocatalytic CO2 reduction to yield CO with very high selectivity (> 99%) in an aqueous solution.
