利用ZnSO4和Ti（SO4）2为原料，在合成纳米TiO2粉体的基础上，将TiO2微粉分散在（NH4）2CO3溶液中，进一步将Zn(2+)以ZnCO3的形式沉淀出来，于300℃煅烧2h，即可制得纳米级ZnO－TiO2复合粉体，其粒径的30～95nm。利用紫外分光光度计检测其吸收紫外线的性能，发现在200～370nm的波段范围内，约90％以上的紫外线被吸收。
Using ZnSO4 and Ti (SO4) 2 as raw materials, TiO2 powder was dispersed in (NH4) 2CO3 solution on the basis of the synthesis of nano-TiO2 powder, Zn (2+) was further precipitated as ZnCO3, Calcination 2h, you can get nanoscale ZnO-TiO2 composite powder, the particle size of 30 ~ 95nm. Using UV spectrophotometer to detect the UV absorption properties, found that in the wavelength range of 200 ~ 370nm, about 90% of the UV absorption.
