摘要
采用气相扩散-沉积-光还原法制备了可见光响应复合光催化剂Ag/AgCl@NH_2-UiO-66。通过X射线衍射(XRD)、电子扫描显微镜(SEM)、X射线能谱(EDS)、紫外可见漫反射光谱及X射线光电子能谱(XPS)等对催化剂的结构进行了表征。结果表明Ag/AgCl@NH_2-UiO-66具有优良的光催化活性,可见光条件下(λ≥420nm)对20mg·L^(-1)罗丹明的降解效率14min即可达到98%。
A novel visible-light responsive photocatalyst, Ag/AgCl@NH2-UiO-66, was synthesized via vapor diffusion-photoreduction strategy. The as-prepared composite was characterized by X-ray diffraction, scanning electron microscopy, energy dispersive X-ray spectroscopy, ultraviolet-visible diffuse reflection spectra and X-ray photoelectron spectroscopy. Due to the synergistic effect between Ag/AgCl and NH2-UiO-66, the visible-light responsive photocatalyst exhibited excellent photocatalytic activity. The degradation efficiency of the composite to 20 mg·L^-1 Rhodamine B can be reached to 98% within 14 min under visible-light irradiation （λ ≥420 nm）.
