| 摘 要： | 以粗氧化锌和冰乙酸为原料，采用炭吸附水热法制备纳米氧化锌粉体。通过热重/差热仪（TG-DTA）、X射线衍射仪（XRD）、透射电镜（TEM）和紫外可见光谱仪（UV-Vis）等对所得催化剂的焙烧温度、物相、微粒尺寸及光吸收性能进行表征。结果表明：炭黑的吸附有效阻止了纳米氧化锌在制备、干燥以及焙烧过程的团聚和烧结，600 ℃焙烧制备的催化剂颗粒均匀，分散性好，团聚较少，平均晶粒尺寸为20 nm，比表面积约为85.25 m2/g。纳米氧化锌作光催化剂对甲基橙进行光催化降解，在60 min内降解率为97%。

| Abstract: | Nano-sized zinc oxide（ZnO） powder was prepared by carbon adsorption hydrothermal method with crude zinc oxide and glacial acetic acid as raw materials.The calcination temperature，crystalline phase，particle size，and optical absorption properties of the as-prepared ZnO were characterized by means of thermogravimetric analysis-differential thermal analysis（TG-DTA），X-ray diffraction（XRD），transmission electron microscope（TEM），and UV-Vis spectroscopy etc..Results
showed adsorption of activated carbon could prevent powder′s agglomeration during the preparation，drying，and calcination processes．Nano-sized ZnO with average grain size of 20 nm and surface area of about 85.25 m2/g was prepared at 600 ℃， which had uniform size，high dispersion behavior，and little agglomeration.The result of photocatalytic reaction for the degradation of methyl orange under ultraviolet light radiation showed the degradation of methyl orange almost complete（the degradation rate was 97%） in 60 min． |
