摘要

采用溶剂热法合成均苯三甲酸-三维铜基配合物[Cu3(btb)2,MOF-14]材料,合成的MOF-14比表面积为1278m2/g。采用X-射线粉末衍射(XRD)、傅里叶变换红外(FT-IR)、场发射扫描电子显微镜(FE-SEM)等手段分析了其化学组成及结构,并对MOF-14处理偶氮染料废水刚果红(CR)进行了研究。研究结果表明,在吸附80min条件下,过氧化氢(H2O2)对CR的降解能力几乎为零,单独的Cu3(btb)2对CR的降解率为29.22%,然而当Cu3(btb)2与少量H2O2共同作用条件下,对CR的降解率猛然提升,达到94.65%。

Abstract

The Cu3(btb)2(btb=4,4′,4″- benzenetribenzoate,MOF-14) porous materials was synthesized by hydrothermal synthesis and characterized by powder X-ray diffraction(XRD),fourier transform infrared spectrometer(FT-IR),field emission scanning electron microscopy(SEM) and nitrogen adsorption(BET).Succeeded in the characterization of MOF-14 compound with estimated Langmuir surface erea of 1278 m2/g.The material was used to treat the azo dye wastewater.The results showed that H2O2 was barely works alone in the azo dyes wastewater within 80min while Cu3(btb)2 alone can treat 29.22% of wastewater.But when Cu3(btb)2 was added with a small amount of hydrogen peroxide (H2O2),the degradation efficiency was increased to 94.65%.
