摘要

Highly-efficient sono-solar-induced degradation of organic dye by the piezophototronic/ photocatalytic coupling effect of FeS/ZnO nanoarrays was achieved. A steel screen was. used as the substrate for supporting FeS/ZnO nanoarrays, and the nanoarrays were. vertically and uniformly grown on the substrate via a wet-chemical route. Under ultrasonic and solar irradiation, FeS/ZnO nanoarrays have high sono-photocatalytic activity for degrading methylene blue in water. The photogenerated carriers can be separated by a. piezoelectric field and a. built-in electric field, resulting in a. low recombination rate and high photocatalytic efficiency. The piezophototronic and photocatalytic effects were. coupled together. The experimental/theoretical data indicate that this novel wastewater treatment can. co-use mechanical and solar energy in. nature, and so is. a promising technology for. environment improvement.
