Cryo-induced closely bonded heterostructure for effective CO2 conversion: The case of ultrathin BP nanosheets/g-C3N4

Black phosphorus (BP), an interesting and multi-functional non-metal material, has attracted widespread attention. In this work, 2D BP/2D g-C3N4 heterostructure had been fabricated at extremely low temperature, which was used to reduce CO2 for the first time. With introduction of 2D BP, the separation of photogenerated holes and electrons was extremely boosted, and composites showed excellent photocatalytic performance (CO2 to CO). Meanwhile,...
