甘氨酸辅助合成BiOI及其模拟太阳光光催化性能研究
Glycine Assisted Synthesis of BiOI and Enhanced Simulated Sunlight Activity
摘要
Abstract
Tetragonal BiOI with uniform size petal composed microspheres morphology was synthesized by one-step hydrothermal method using glycine molecules as templates and Bismuth nitrate as the source of Bi3+.The physicochemical properties of the fabricated BiOI was characterized by X-ray powder diffraction (XRD),scanning electron microscope (SEM),UV-Vis diffuse reflection spectroscope (UV-Vis/DRS),N2 adsorption-desorption isothermal.The molar ratios of Bi(NO3)3·5H2O and glycine (Bi:G),and hydrothermal time played important roles in the preparation process,which affected the morphology,structure,and light absorption properties of BiOI.Rhodamine-B and salicylic acid were used as the goal pollutants to evaluate the simulated sunlight catalytic properties of BiOI prepared with or without glycine.The BiOI prepared with Bi:G=1:2 and hydrothermal time of 12 h exhibited the excellent degradation activity.After 40 min irradiation,Rhodamine-B and salicylic acid degradation rate constant by the glycine assisted synthesis of BiOI reached 0.0232 and 0.0223 minl,respectively.However,the photocataytic degradation rate constant of BiOI prepared without glycine was only 0.0111 and 0.0143 min-1.Compared with BiOI prepared without glycine,the degradation activity improved sharply.The enhanced photocatalytic activity was mainly ascribed to regular morphology and big BET surface area of the BiOI prepared with the addition of glycine.关键词
