摘要
使用尿素-氯化胆碱低共熔溶剂(UCC-DES),采用水热合成和反溶剂(乙醇)法,以化工材质ZnO粉末为原料制备了分层的球状微/纳米ZnO晶体.分析了反应时间、反溶剂的种类和含量对ZnO晶体形貌的影响以及ZnO晶体析出的原因.并将制备的分层球状ZnO微/纳米晶体应用于光催化降解甲基橙.结果表明,制备的ZnO晶体对甲基橙有良好的光催化降解性能.
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 chemis- try and should have widespread application in the future.
