In2O3/BiOBr复合光催化剂的制备及其光催化CO2还原性能
Preparation of In2O3/BiOBr composite photocatalyst and its performance for photocatalytic CO2 reduction
摘要
Abstract
xIn2O3/BiOBr S-scheme heterojunction(x%is the mass fraction of In2O3 to BiOBr)composite photocatalysts were successfully prepared by a water bath impregnation method.The morphology,struc-ture,specific surface area,light absorption property,the separation and transfer efficiency of photogener-ated carriers of catalysts were studied.The results showed that In2O3 and BiOBr were tightly bound,and In2O3 was uniformly dispersed on BiOBr nanoflowers.The xIn2O3/BiOBr composite photocatalyst exhibi-ted stronger absorption of visible light,and the addition of In2O3 improved the separation efficiency of the photogenerated carrier on BiOBr.The photocatalytic CO2 reduction reaction over xIn2O3/BiOBr was stud-ied under visible light irradiation.When the In2O3 loading mass percentage was 5%,5In2O3/BiOBr exhib-ited the best performance for photocatalytic CO2 reduction,and the CO production reached 16.12 μmol/g after reaction for 4 h,which was 1.68 times that of BiOBr.关键词
