| Abstract: | Multi-layered spherical ZnO micro/nano-crystals were synthesized by means of hydrothermal and antisolvent method from the urea-choline chloride deep eutectic solvent(UCC-DES). The effects of reaction time, amount and concentrations of antisolvents on the morphology of ZnO micro/nano-crystals were investi-gated, and the formation of ZnO micro/nano-crystals was discussed. Furthermore, the photocatalytic activities of the as-prepared ZnO crystals for the degradation of methyl orange were investigated. The results indicate that multi-layered spherical ZnO micro/nano-crystals exhibit a superior photocatalytic activity.The synthetic method of ZnO is facile, safe and environmentally friendly, it is in line with the requirements of green chemistry and should have widespread application in the future. |
