Abstract

Abstract: Abstract : This research was designed for the first time to investigate the photocatalytic activities of MoO3 /g-C3 N4 composite in converting CO2 to fuels under simulated sunlight irradiation. The composite was synthesized using a simple impregnation-heating method and MoO3 nanoparticles was in situ decorated on the g-C3 N4 sheet. Characterization results indicated that the introduction of MoO3 nanoparticles into g-C3 N4 fabricated a direct Z-scheme heterojunction structure. The effective interfacial charge-transfer across the heterojunction significantly promoted the separation efficiency of charge carriers. The optimal CO2 conversion rate of the composite reached 25.6 μmol/(h gcat ), which was 2.7 times higher than that of g-C3 N4 . Additionally, the synthesized MoO3 /g-C3 N4 also presented excellent photoactivity in RhB degradation under visible-light irradiation.
