| 摘 要： | 以Fe（NO3）3、煤矸石和NaOH为原料,采用沸腾回流法制得了一系列不同质量比的α-Fe2O3/煤矸石复合光催化剂。采用场发射扫描电子显微镜（FESEM）、X射线衍射仪（XRD）及紫外-可见漫反射光谱（UV-Vis DRS）等多种手段对产物做了表征。以五氯酚为目标降解物,考察了模拟太阳光照下样品的光催化效果。结果表明,将球形α-Fe2O3负载于改性煤矸石表面可有效提高其光催化活性,且α-Fe2O3/煤矸石复合光催化剂的性能与α-Fe2O3的含量有关,当α-Fe2O3与煤矸石的质量比为30∶100时,样品的光催化效果最佳,180 min内即可将五氯酚降解完全。此外,α-Fe2O3/煤矸石复合光催化剂还具有可重复使用的特点。

| Abstract: | Using ferric nitrate,coal gangue and sodium hydroxide as the raw materials,α-Fe2O3/coal gangue composite photoc-atalysts with different mass ratios of α-Fe2O3 were successfully prepared by boiling reflux method.Field emission scanning electron microscopy（FESEM）,X-ray powder diffraction（XRD） and UV-Vis diffuse reflectance spectra（UV-Vis DRS） were used to characterize the products.The photocatalytic activity of as-prepared samples was investigated for degradation of pentachlorophenol under simulated sunlight.The results indicated that loading spherical α-Fe2O3 composite on the surface of modified coal gangue could effectively improve its catalytic activity,and there was a close relationship between the photocatalytic performance of α-Fe2O3/coal gangue composites and the content of α-Fe2O3.When the mass ratio of α-Fe2O3 to coal gangue was 30∶100,α-Fe2O3/coal gangue composite photocatalyst showed the highest performance and pentachlorophenol was almost completely degraded within 180 min.In addition,this kind of catalyst could be used repeatedly. |
