Photocatalytic conversion of carbon dioxide to methanol over different precursors of graphitic carbon nitride supported on fibrous silica iron
In this study, the graphitic carbon nitride (g-C 3 N 4 ) was successfully synthesized through thermal polymerization under three different g-C 3 N 4 precursors such as urea (U-gC 3 N 4 ), melamine (M-gC 3 N 4 ) and dicyandiamide (D-gC 3 N 4 ) and then doped into the fibrous silica iron (FSFe), denot...
