CuGaO₂ thin films for photocatalytic applications were successfully fabricated via spin-coating by mixing Cu₂O and GaO₂H precursor sols at a specific molar ratio, followed by annealing at 270 °C. The film surface exhibited dot-like structures (~50 nm in diameter) with similar-sized voids, resulting in a porous morphology. Furthermore, their photocatalytic properties were significantly enhanced compared to Cu₂O films.
