中文摘要：

H2O2被认为是ZnO产生抗菌性能的主要原因。利用专一化学反应,结合分光光度分析,定量检测了四针状氧化锌晶须、纳米氧化锌和普通工业级氧化锌悬浮液中过氧化氢的产生量,并讨论了形貌和光照条件对ZnO悬浮液中过氧化氢产量的影响。结果表明,上述3种ZnO悬浮液在模拟日光、紫外光及无光条件下都可以产生过氧化氢,四针状氧化锌晶须产生的过氧化氢量最多,其次是纳米氧化锌,最后是普通氧化锌;分析认为,形貌对过氧化氢产量的影响程度超过粒径和比表面积。

英文摘要：

Hydrogen peroxide（H2O2）is considered as one of the primary factors in antibacterial mechanism of zinc oxide powder slurry.The H2O2 generated from the suspensions of zinc oxides with different morphologies under different light excitations were studied according to specified reaction followed by UV-Vis spectrophotometer.The results indicated that H2O2 was detected out from the three kinds of zinc oxide suspensions under simulated sunlight,darkness or UV-light.The productivities of H2O2 from the related three kinds of ZnOs were ranked as T-ZnO,n-ZnO and p-ZnO,whatever the light excited or not.There was no apparent proportional relationship between light conditions and the production of H2O2,and the morphology had more obvious effect than particle size and/or specific surface area.
