摘要：
Nano-ZnO powder were prepared through gel-sot method with zinc acetate and lithium hydroxide as crude material. Nano-ZnO was analyzed by XRD, SEM, TEM, UV-Vis and determined photocatalytic activity at photocatalytic reactor. The results show that nano-ZnO has a integrate crystal and its size is 6.6nm with the best photocatalytic performance, when calcined at 350 degrees C. The best ZnO dosage is 0.1g/L with 97% Methylene Blue removal after 30min. Compared with different photocatalytic reactor, the airlift reactor is obviously better than bubbling reactor and stirring reactor.
