Augmenting the Photocatalytic Performance of Direct Z-Scheme Bi2O3/g-C3N4 Nanocomposite

Huge demands for photocatalytically efficient visible-light-induced catalysts have spurred widespread interest in building adaptable heterojunctions. Here, we used situ thermal polymerization to synthesise the Z-scheme Bi2O3/g-C3N4 heterojunction. The optical, structural, chemical, compositional and photocatalytic behaviours of samples were analysed through various analytical techniques methylene blue (MB) dye degradation reaction. Among ratios heterojunction composites, 1:1 ratio showed improved catalytic activity, which attained 91.2% efficiency after 120 min visible-light exposure. was calculated under environmental conditions by varying concentration, solution pH catalyst dosage. A mechanism proposed light results. potential suggested explain trapping experiments supported it. Last but not least, this strategy might be helpful prepare photocatalyst organic pigments.
