Preparation and properties of ZnO by ionic liquid assisted sol-gel method

摘要

Zinc oxide nanopowder was prepared by sol-gel method using oxalic acid and zinc acetate as starting material for the first time.And Rhodamine B as the target material to study the different levels of ionic liquids on the photocatalytic performance of nano-ZnO.ZnO powder was determined by SEM and XRD for introduction of ionic liquids derived from nano-ZnO surface morphology and crystal before and after.The results show that nano-ZnO catalyst surface pores increased and grain refinement by adding ionic liquid which is conducive to nano-ZnO on the photocatalytic degradation of Rhodamine B.
