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