摘　　要：采用水热法合成了磷钨酸(PTA)包覆的MIL-101-Cr复合材料,通过XRD、TG、FT-IR等方法测试磷钨酸(PTA)包覆前后以及包覆不同量的情况下,复合材料的理化性质,并探究其对染料罗丹明B的光催化性质。实验结果表明:当MIL-101-Cr负载磷钨酸的W:Cr摩尔比为0.2时,其催化反应活性达到最高,罗丹明B降解率达到80%,且该催化剂材料稳定,晶体结构不易发生变化。MIL-101-Cr composite coated with phosphotungstic acid(PTA)was synthesized by hydrothermal method.The physicochemical properties of the composite before and after coated with PTA and coated with different amounts were tested by XRD,TG,FT-IR and other methods,and the photocatalytic properties of the composite for rhodamine B were explored.The experimental results showed that when the W:Cr molar ratio of phosphotungstic acid supported on MIL-101-Cr was 0.2,the catalytic activity reached the highest,and the degradation rate of rhodamine B reached 80%.The catalyst material was stable,and the crystal structure was not easy to change.
