摘　　要：本文将Keggin型多酸H_(3)PMo_(12)O_(40)和Dawson型多酸(NH_4)[P_(2)Mo_(18)O_(62)]·14.2H_(2)O引入到丝瓜络碳化后的多孔碳材料中获得了两种新型多酸基碳材料POM@C(记为PMo_(12)@C和P_(2)Mo_(18)@C)。对此材料进行了形貌和组成的表征,同时基于碳材料的多孔性和多酸的阴离子性,探究了其对阳离子染料的吸附性能。结果表明,生物碳材料的大孔道内均匀分布多酸纳米粒子,并且对阳离子染料罗丹明B表现出良好的吸附作用。本论文的研究为合理设计出更多的性能优异的污水处理材料提供了思路。In this paper,Keggin type H_(3)PMo_(12)O_(40) and Dawson type(NH_4)[P_(2)Mo_(18)O_(62)]·14.2H_(2)O were introduced into the porous carbon materials after carbonization of loofah,and two new polyoxometalate based carbon materials PMo12@C and P_(2)Mo_(18)@C were obtained.The morphology and composition of the materials were characterized.Meanwhile,based on the porosity of the carbon material and the anionic property of the polyoxometalate,the adsorption performance of the cationic dye was investigated.The results show that the polyoxometalate nanoparticles are uniformly distributed in the microporous channels of the biocarbon material,and the composite materials show good adsorption effect on cation dye Rhodamine B.The research in this paper provides ideas for the rational design of more excellent wastewater treatment materials.
