Facile Fabrication of Bi2MoO6/g-C3N4 Heterojunction Nanosheets: Facile Synthesis and Enhanced Visible Light Photocatalytic Property

Abstract

Exploring an efficient and photostable heterojunction photocatalyst is a pivotal scientific topic for global energy and environmental concerns. Herein, we demonstrated an efficient and facile strategy to synthesize of Bi2MoO6/g-C3N4 heterojunctioned nanosheets (denoted as BM/CNs hereafter). The photocatalytic degradation of Rh B as a model pollutant indicated that the optimized 40%-BM/CNs catalyst could degrade 96.3% Rh B solution within 120 min. The degradation efficiency was 4.2 times and 6.8 times higher than that of pure Bi2MoO6 and pristine g-C3N4, respectively. The enhanced photocatalytic performance of 40%-BM/CNs catalyst might be mainly attributed to the construction of Z-scheme heterostructure, which effectively improved the efficiency of electron–hole separation. This work proposed a possible Z-scheme photocatalytic mechanism to elucidate the enhanced photochemical properties.
