摘要：
A simple template-directed synthesis method was employed to prepare WO3, Fe2W3O12, 5% WO3/Fe2W3O12, 10% WO3/Fe2W3O12, and 15% WO3/Fe2W3O12 composite materials. The WO3/Fe2W3O12 composite material is mainly composed of cubic WO3 (JCPDF card no. 43-1035) and tetragonal Fe2W3O12 (JCPDF card no. 24-0538) and does not contain any other impurities. The WO3/Fe2W3O12 composite material exhibits porous structure and the pore size and specific surface area decreases with the increase in WO3 content. The E-g values of WO3, Fe2W3O12, 5% WO3/Fe2W3O12, 10% WO3/Fe2W3O12, and 15% WO3/Fe2W3O12 composite materials are 2.08, 1.30, 1.63, 2.38, and 1.51 eV, respectively. The 15% WO3/Fe2W3O12 composite materials exhibits the highest emission intensity. This result is inconsistent with the results previously reported, possibly because WO3 and Fe2W3O12 form a type II band arrangement.
