Preparation of Porous ZnO Film by Zinc Oxalate Recurrence Method

Abstract

This paper presents a method called zinc oxalate (ZnC2O4) recurrence method to prepare porous zinc oxide (ZnO) films via templating with polystyrene (PS) spheres. Effects of calcination time and temperature, concentration of ZnC2O4 in precursor solution on ZnO films were studied. Optimal synthetic conditions and structural features of ZnO films were investigated by DTA, XRD and SEM. Experimental results show that porous ZnO films can be easily prepared by zinc oxalate recurrence methods.
