摘要：
The synthesis of a dual Z-scheme heterojunction, Bi2MoO6/MnWO4/g-C3N4 (BMCM-x), enriched with oxygen voids, has been synthesized by an in-situ generation method. The ideal composite specimen, BMCM-50, managed to break down over 85 % of Iohexol in a span of 40 min. The emergence of oxygen voids serves to inhibit the merging of photogenerated carriers and fosters the creation of reactive radicals. The dual Z-scheme heterojunction is capable of isolating photogenerated carriers and enhancing redox capacity, markedly boosting BMCM-50's photocatalytic breakdown efficiency.
