The existence of organic, inorganic, and microbiological contaminants in water bodies continues to pose a serious threat public health worldwide. photocatalytic elimination these using copper bismuthate (CuBi2O4) heterostructures has been the subject numerous studies. CuBi2O4 have demonstrated their effectiveness as photocatalyst because longer charge carrier lifespan, enhanced capacity absorb solar light, greater separation. various techniques for fabricating such hydrothermal, sol-gel, solid state, solvothermal, electrospinning, spray pyrolysis, electrodeposition are extensively discussed this review paper. A wide range different mechanisms action also covered. degradation pollutants by is presented detail. Furthermore, thorough critical discussion included about prospects difficulties purification wastewater.

Replacing the oxygen evolution reaction (OER) in photoelectrocatalytic (PEC) water splitting with glycerol oxidation (GOR) not only enhances hydrogen production but also generates high-value byproducts. In this study, we developed a ternary photoanode, Co-LDH/Bi2O3/TiO2, by loading particulate Bi2O3 and linear Co-LDH onto TiO2 nanorod for conversion production. The characterization results confirm formation of coupled interfaces between TiO2, which improves visible light utilization promotes type II heterojunctions, resulting significant suppression electron–hole recombination an improvement PEC performance. Fourier transform infrared (FT-IR) spectroscopy revealed that Co-LDH/Bi2O3/TiO2 photoanode exhibited stronger adsorption intermediate hydroxyl group more effective desorption DHA compared to binary photoanodes (Co-LDH/TiO2 Bi2O3/TiO2), high-selectivity DHA. Mechanistic studies density function theory calculations have shown Co-LDH/TiO2 oxidizes mainly through hole oxidation, Bi2O3/TiO2 radical (•OH) oxidation. Therefore, constructed (Co-LDH/Bi2O3/TiO2) dual heterojunction converts pathways •OH This work demonstrates promising strategy developing high-performance systems production, leveraging synergistic effects multisemiconductor heterojunctions multiple pathways, offering potential practical applications.
