Photocatalytic technology has great potential in environmental remediation due to the advantages of being green and cost-effective. Still, drawbacks such as high carrier recombination and poor photo-utilization efficiency hinder its large-scale application. Fortunately, defect modulation has been proven to be an effective tactic for solving the above problems. In this study, cationic vacancies were introduced in layered bismuth molybdate (Bi2MoO6) by controlled alkali etching. The results showed that the optimized Mo vacancy concentration increased the degradation efficiency of tetracycline hydrochloride to 82 % with a kinetic constant 2.4 times higher than that of bulk Bi2MoO6, which is superior to most reported Bi-based catalysts. In-situ KPFM, PL, and photoelectrochemical measurements confirm that the boosted activity is attributed to photo-excited charge carriers' excellent separation and migration ability. This work supplies a feasible strategy to enhance the photocatalytic performance of Bi2MoO6 and provides a novel insight into designing other advanced materials for photocatalytic applications.
