摘要： 采用复合表面活性剂作分散剂，用微波辐射法制备了较大比表面积的纳米复合半导体材料WO3·NiO·0.33H2O，利用 XRD、TEM、BET和UV-Vis漫反射光谱技术对固体材料的组成结构和光吸收性能进行了表征。结果表明，微波辐射法制备的材料晶粒小，孔隙率大，结晶度高，比表面积大，为66.37 m2/g；材料WO3·NiO·0.33H2O光响应波长达600 nm，增强了光能利用率及光催化活性。

Abstract: Composite semiconductor nano crystallites WO3·NiO·0.33H2O were synthesized by using composite surfactant as dispersant under microwave radiation. The structure and photo absorption property were characterized by using XRD，TEM，BET，XPS and UV-Vis D R S techniques. Results showed that the prepared nano crystallites have smaller crystallite size，larger hole，larger specific surface area of 66.37 m2/g and broad wavelength absorption up to 600 nm. Therefore，the prepared nano crystallites have improved light energy utilization efficiency and enhanced photocatalytic activity.
