铁掺杂氯氧化铋片簇的球磨制备及光降解性能
Ball Milling Preparation and Photodegradation Performance of Iron Doped Bismuth Oxychloride Clusters
摘要
Abstract
Bismuth oxychloride(BiOCl),a layered multifunctional material,has a good application prospect in the field of photocatalytic environmental remediation.Herein,trace Fe3+doped small layered BiOCl nanosheets(Fe-BOC)were successfully prepared by using ball milling assisted hydrolysis method with FeCl3 as the Cl-source.The results indicate that the Fe-BiOC-2 with 0.38％ofFe3+,prepared by milling the mixed precursor of Bi(NO3)3·5H2O and FeCl3 in a molar ratio of 3∶1,has the largest specific surface area(9.77 m2/g)and pore volume(0.09 cm3/g),about 5.20 and 3.00 times of pure BiOCl,respectively.Due to the formation of doping energy levels,the utilization of visible light and the migration of charge carriers are effectively enhanced,meanwhile,the recombination of photo-generated electron hole pairs are suppressed.The photocatalytic experiment shows that Fe-BOC-2 photocatalyst has the most superior photocatalytic activity for RhB degradation,with approximately 99.54％of RhB being degraded within 30 minutes under the irradiation of a 300 W xenon lamp light source.The testing results also prove that photo-generated holes on the surface of Fe-BOC-2 are the main degradation active carriers,playing a dominant role during the photodegradation of Rh.关键词
