摘要 太阳光中有一多半是红外光,而利用红外光的光催化反应却鲜有报道。本研究制备了一种全光谱响应的W18O49/g-C3N4异质结催化剂,并考察了催化剂光降解罗丹明B(RhB)的性能。采用X射线衍射(XRD)、氮气吸附、紫外-可见-近红外(UV-Vis-NIR)光谱、扫描电子显微镜(SEM)、透射电子显微镜(TEM)、荧光光谱(PL)、X射线光电子能谱(XPS)和电化学阻抗谱(EIS)等手段对催化剂进行了表征。结果显示制备的催化剂对250～1 800 nm范围内的光均显示出较强的吸收。制备的异质结催化剂对RhB的降解速率常数达到0.015 9 min-1,分别是纯g-C3N4和W18O49的5.3倍、11.4倍,且具有优异的催化稳定性。W18O49一方面作为红外光吸收材料,提高了催化剂对光的吸收利用,另一方面与g-C3N4组成异质结催化剂,显著提高了光生电荷分离效率。此外,本研究还考察了W18O49/g-C3N4异质结催化剂降解RhB可能的反应机理。

Abstract: More than half of the solar spectrum is near infrared (NIR) light. However, the report concerning the photocatalytic reaction using NIR light is rare. In this work, a full-spectrum-driven W18O49/g-C3N4 heterojunction catalyst was prepared and the photocatalytic RhB degradation ability was investigated. X-ray diffraction, N2 adsorption, UV-Vis-NIR spectroscopy, scanning electron microscope, transmission electron microscope, photoluminescence, X-ray photoelectron spectroscope and electrochemical impedance spectra were used to characterize the prepared catalysts. The result indicates that as-prepared W18O49/g-C3N4 heterojunction catalysts display strong light absorption in the region of 250—1 800 nm. The reaction rate constant for W18O49/g-C3N4 heterojunction catalyst arrives 0.015 9 min-1, which is 5.3 times and 11.4 times higher than that of neat g-C3N4 and W18O49, as well as excellent catalytic stability. In addition, the mechanism of degradation of RhB by W18O49/g-C3N4 heterojunction catalyst was investigated.
