Preparation, characterization and photocatalytic performance of hetero-structured CuO-ZnO loaded composite nanofiber membranes

Abstract

Owing to the nano-effect of nanofibers and special properties of semiconductor oxides, inorganic semiconductor oxides loaded composite nanofibers (CNFs) have been widely applied in environmental monitoring, industry, aviation, transportation and other fields. In this paper, the hetero-structured CuO-ZnO loaded CNF membranes (CNFMs) were prepared successfully by a combination of electrospinning technology, heat treatment and hydrothermal method. The effects of electrospinning, heat treatment and hydrothermal parameters on morphology, structure and properties of the CNFMs were investigated, and the optimal process parameters were determined. Then the hetero-structured CuO-ZnO loaded CNFMs obtained under the condition of the optimal process parameters were applied to photocatalytic degradation of methyl orange, and it was found the CNFMs could be reused to degrade methyl orange at least three times, and the degradation rate remained above 90%.

Design of microstructure and performance testing of high-pressure ZnO grain boundary layer

“…In the literature [12], ZnO/EP composites were prepared by sol-gel method using ZnO powder and epoxy resin E-51 as raw materials. In the literature [13], PAN/ZnO composite nanofiber filter membranes were prepared by doping ZnO nanoparticles into PAN solution, and their microstructure, air permeability, moisture permeability, UV protection, and filtration properties were tested.…”
