Description
Summary:The study aimed to investigate the photocatalytic activity of porous copper gallate (CuGa 2 O 4 ) thick film with significant wall dimensions. The thick film was meticulously fabricated using tape casting systems, with CuGa 2 O 4 nanoparticles synthesized by Sol–Gel technique and subsequently transformed into gels for the tape casting process. Rietveld refinements were employed to elucidate the crystal structure and lattice parameters of the CuGa 2 O 4 spinel oxide lattice. Moreover, electronic energy configurations and optical transmittance measurements were acquired through UV-visible spectrophotometry. The correlations between the crystal structure, band gap change and formation of electronic energy levels in relation to the photocatalytic performance of CuGa 2 O 4 were explored. The comprehensive examination provides valuable insights into the complex interaction between material properties and photocatalytic behavior, offering a nuanced understanding of the potential applications of porous CuGa 2 O 4 thick films in various technological fields.
