Abstract
Semiconductor-assisted photocatalytic treatment has been regarded as a promising technique to dispose the dye-contaminated wastewater and gained pronounced attention recently. Here, we demonstrated a kind of Ga2O3 nanometer hollow sphere photocatalysis by template-assisted technique and applied it on the degradation of Rhodamine B (RhB). It was found that the hollow spherical structure of photocatalyst can greatly enhance the photo absorption and reduce the recombination of photogenerated carriers, thus improve the photocatalytic performance. This study provides a new method for efficient photocatalytic degradation of RhB, and provides a new idea for subsequent degradation work.
