Cs₃Bi₂Br₉/g-C₃N₄ Direct Z-Scheme Heterojunction for Enhanced Photocatalytic Reduction of CO₂ to CO.

ABSTRACT: Lead-free halide perovskite derivative Cs₃Bi₂Br₉ has recently been found to possess optoelectronic properties suitable for photocatalytic CO₂ reduction reactions to CO. However, further work needs to be performed to boost charge separation for improving the overall efficiency of the photocatalyst. This report demonstrates the synthesis of a hybrid inorganic/organic heterojunction between Cs₃Bi₂Br₉ and g-C₃N₄ at different ratios, achieved by growing Cs₃Bi₂Br₉ crystals on the surface of g-C₃N₄ using a straightforward antisolvent crystallization method. The synthesized powders showed enhanced gas-phase photocatalytic CO₂ reduction
