Scale-up synthesis of monolayer layered double hydroxide nanosheets via separate nucleation and aging steps method for efficient CO2 photoreduction

Photocatalytic CO2 reduction is one of the most promising ways to solve the energy crisis and the greenhouse effect. Among the abundant products (CO, HCOOH, CH3OH, CH4, etc), it is difficult to reduce CO2 through 8 electrons to CH4. Monolayer layered double hydroxides (denote as LDHs) have drawn wide attention and interest due to the abundant defects and unique electronic structure. However, the monolayer LDHs can be obtained mainly in the lab...
