. The as-synthesized ZnO flowers exhibit a significant enhancement of photocatalytic capability toward degrading methyl blue (MB) under UV light, the photodegradation of MB reaches 95.60%, only within 2 h of adding the as-synthesized ZnO in the MB solution under UV irradiation. Furthermore, the photodegradation could be described as the pseudo-first-order kinetics with degradation rate......
with that of the TiO2 hollow spheres. The photodegradation of methyl orange (MO) was used to evaluate the photocatalytic activity of the catalysts under UV and visible light irradiation. 99.2% and 81% MO...; hollow sphere; hydrothermal-template method; photodegradation 由于具有氧化能力强,催化活性高,物化性质稳定,价廉,无毒等优点,TiO2已成为废水处理,空气净化和杀菌自洁等光催化领域研究最为深入的一种光催化材料[1-3].但TiO2的禁带较宽,只有能量较高的紫外线才能激发其光催化活性.虽可考虑利用太阳光作为光源,但其中紫外线只占4%左右,因而太阳......
