Ba4In2O 7的水热控制合成及其光催化性能
Hydrothermal synthesis of Ba4 In2 O7 and its photocatalytic performance
摘要
Abstract
Ba(NO3 )2 and In(NO3 )3 are used as raw materials ,the synthesis of Ba4 In2 O7 is studied using hydrothermal process .The effects of molar ratio Ba :In (Ba/In) ,NaOH concentration (cg ) ,hydrothermal reaction temperature (T) ,hydrothermal reaction time (t) ,calcination tem‐perature (Tb ) and time (tb ) on the conformation of Ba4 In2 O7 are investigated respectively ,and the condition of optimal synthesis is established .T he as‐prepared samples are characterized by X‐ray diffraction (XRD) ,UV‐visible diffuse reflectance spectroscopy (UV‐vis DRS) ,termogravim‐etric analysis‐differential thermal analysis (TG‐DTA ) and N2 adsorption‐desorption isotherms (BET ) .The degradation of Rhodamine B (RhB) is served as the degradation model ,the photo‐catalytic performance of Ba4 In2 O7 samples is evaluated by monitoring the photocatalytic decompo‐sition of RhB .T he results show that the particles of as‐prepared Ba4 In2 O7 has had a porous hon‐eycomb structure .The degradation rate of RhB reaches 97 .3% under the irradiation of high pres‐sure mercury lamp (125 W) in 180 min .关键词
