Through XRD analysis, as the temperature of cosolvent and mass transport goes up, the wave peak intensify of tin dioxide becomes more obvious. By means of SEM, tin dioxide particulates are found evenly distributed on the matrix and the quantity of particulates become higher with the increasing cosolvent concentration. The size of particulates is about 30-50nm.
