Abstract
Abstract A novel BiOIO3/MoS2 (BM-x) 2D/2D heterostructure was firstly constructed by hybridizing BiOIO3 with MoS2 through solvothermal process. The formation of BM-x 2D/2D heterostructure with higher specific surface area and larger interfaces can offer ample channel for the transmission of charge, confirmed by SEM, TEM, BET and EIS. Introduction of MoS2 could improve light harvesting abilities of BM-x composites, which was demonstrated by DRS. Moreover, a staggered type-Ⅱ heterojunction and built-in electric field between BiOIO3 and MoS2 were formed, facilitating the separation of photogenerated carriers, proven via transient photocurrent response and PL. The BM-x composites could be applied to the photocatalytic degradation of rhodamine B (RhB). Above properties endow BM-x composites enhanced photocatalytic efficiencies for degradation of RhB than pure BiOIO3 under simulated solar-light irradiation, and the BM-1.0 composite showed the optimized degradation rate constant (0.04189 min−1), which is 5.2 times higher than that of pristine BiOIO3 (0.00811 min−1). Free radical scavenging experiments reveal that h+ and •O2− are primarily responsible for the photocatalytic degradation of RhB in this system, and a possible type-Ⅱ heterojunction mechanism with dye sensitization was proposed.
