Carbon nanospheres (CNSs) were prepared by hydrothermal synthesis, and coated with TiO and ZnO nanofilms by atomic layer deposition. Subsequently, through burning out the carbon core templates hollow metal oxide nanospheres were obtained. The substrates, the carbon-metal oxide composites and the hollow nanospheres were characterized with TG/DTA-MS, FTIR, Raman, XRD, SEM-EDX, TEM-SAED and their photocatalytic activity was also investigated. The results indicate that CNSs are not beneficial for photocatalysis, but the crystalline hollow metal oxide nanospheres have considerable photocatalytic activity.
通过水热合成制备了碳纳米球（CNSs），并通过原子层沉积在其表面涂覆了 TiO 和 ZnO 纳米薄膜。随后，通过烧掉碳核模板，得到了空心金属氧化物纳米球。采用 TG/DTA-MS、FTIR、Raman、XRD、SEM-EDX、TEM-SAED 对基底、碳-金属氧化物复合材料和空心纳米球进行了表征，并研究了它们的光催化活性。结果表明，CNSs 不利于光催化，但结晶空心金属氧化物纳米球具有相当的光催化活性。
