Abstract

Photocatalytic decomposition of carbamazepine using Au nanoparticles modified β-Ga2O3 film was investigated. The crystallization, morphology, optical properties, and electrical properties of the samples were investigated using XRD, SEM, UV–vis absorption spectroscopy, photoluminescence spectra, and photocurrent measurements. In the photocatalytic experiments of carbamazepine degradation, the Au nanoparticles modified β-Ga2O3 films presented a better photocatalytic property than the pure β-Ga2O3 film. The optical transmittance spectra verify that the present of Au nanoparticles can enhance the light harvesting and shrink the bandgap of the β-Ga2O3 film. The photocurrent density and photoluminescence emission spectra indicate that the localized surface plasmon resonance of Au nanoparticles promoted the charge separation and suppressed the charge recombination of photoinduced electron–hole pairs in β-Ga2O3.
