水热法制备Mo掺杂WO3纳米材料及其光致变色性质的研究
Hydrothermal Synthesis and Photochromic Characterization of Mo Doped WO3 Nanomaterial
摘要
Abstract
WO3 is a multi-functional semiconductor, and photochromism is one of the most important characterizations WO3 owns. This work has established a facile method to synthesize Mo doped hexagonal WO3 using W powder, Mo powder and hydrogen peroxide as starting agents and adding Na2SO4 as a mineralizer. The morphology, size, phase structure and component were characterized by applying SEM, XRD, HRTEM, XPS, etc, and it is confirmed that Mo is successfully doped into WO3 as MoxW1-xO3. After irradiated with Xe lamp, the novel MOx-W1-xO3 material holds much better photo-chromic phenomenon than pure WO3. The involved smaller band gap resulted in the more electron produce after irradiation. Moreover, by doping Mo, the electron transfer in this special structure is highly enhanced.关键词
