Abstract
Industrial discharge of synthetic dyes is one of the crucial environment issues need to be resolved. To develop efficient visible light driven photocatalyst, graphitic carbon nitride (g-C3N4) and flower-like copper cobaltite (CuCo2O4) composites were fabricated for the degradation of methyl orange (MO) dye under simulated solar light irradiation. HRTEM result confirms the smart hybrid structure of CuCo2O4 and g-C3N4 were formed with superior distribution of g-C3N4 on the surface of petal-like CuCo2O4 structure. The photocatalytic results demonstrate that CuCo2O4/g-C3N4 (1:2) with H2O2 addition exhibits excellent photodegradation for MO dye (97%) with minimal time (60min). The improved photocatalytic performances can be ascribed due to synergistic dispersion of porous CuCo2O4 (p-type) and g-C3N4 sheets (n-type) semiconductors provide enhanced visible light absorption with efficient separation of electrons–hole pairs. These new insight CuCo2O4/g-C3N4 based photocatalyst applicable for water splitting and treating industrial wastewater.
