Recently, photocatalysis has attracted all-embracing attention as a sustainable and green approach owing to its promising applications in the deterioration of contaminants along with the transformation of solar energy into chemical energy. An efficient visible-light harnessing Copper tungstate photocatalyst has hooked excellent performance because of its peculiar features, including eco-friendliness, low cost, optimum band edge potentials, as well as stability under oxidative and acidic conditions. However, any review depicting the correlation between different morphologies, properties, and performance of CuWO₄ is still absent. Therefore, this review highlighted the energy applications of CuWO₄ photocatalyst, focusing on its morphological dimensions and strategies for photocatalytic performance enhancement. Various fabrication methods, such as hydrothermal, electrodeposition, spray-pyrolysis, co-precipitation, sonochemistry, and solid-state synthesis, are also discussed. Controllable synthesis of distinct morphological nanostructures with the effect of parameters like temperature, pH, solvent, reaction time, and concentration of precursors has been briefly summarized. Nano-structured CuWO₄ was explored to show high photocatalytic activity than pristine CuWO₄. Moreover, different revamp strategies, including doping of parent photocatalyst, loading of co-catalyst on photocatalyst surface, and heterojunction construction, are assumed for the efficient space charge isolation of photo charge carriers suppressing the rapid recombination of photo-generated electron-hole pairs for dynamic photocatalytic activity. The applications of CuWO₄, including photocatalytic water reduction for H₂ generation, photodegradation of dyes and antibiotics, and photoelectrochemical water splitting, have been highlighted. Finally, a brief, conclusive remark regarding present studies and unresolved challenges of nano-structured CuWO₄ are put forth for future perspectives.
