Abstract

The formation of CuAl₂O₄ requires high processing temperature (T > 600 °C). In the present study, single phase CuAl₂O₄ thin film with porous microstructure was successfully synthesized at a low temperature of 400 °C using ultrasonic spray pyrolysis method. The FTIR result confirmed the presence of Cu–O and Al-O vibration from spinel CuAl₂O₄. The CuAl₂O₄ thin film with bandgap of 2.4 eV showed a good photocatalytic characteristic in decomposing methylene blue dye with efficiency of above 80% under solar irradiation for 3 hours.
