Facile synthesis of C3N4-supported metal catalysts for efficient CO2 photoreduction

Facile synthesis of photocatalysts with highly dispersed metal centers is a high-priority target yet still a significant challenge. In this work, a series of Co-C3N4 photocatalysts with different Co contents atomically dispersed on g-C3N4 have been prepared via one-step thermal treatment of cobalt-based metal-organic frameworks (MOFs) and urea in the air. Thanks to the highly dispersed and rich exposed Co sites, as well as good charge separation...
