Nanosheet-assembled hierarchical flower-like g-C3N4 for enhanced photocatalytic CO2 reduction activity

Here, nanosheet-assembled hierarchical flower-like g-C3N4 (CMN) was prepared through a molecular self-assembly and ethanol molecular insertion strategy. CMN possesses enhanced CO2 photoreduction capability due to the enhanced adsorption capacity for CO2, increased specific surface area, and improved carrier diffusion.
