摘要
氧化石墨烯(GO)具有丰富的表面基团,以三聚氰胺(M)泡沫为载体,通过化学键合作用和采用模版法将GO粘接至含MnO_2的M泡沫骨架上,制得3维r GO(石墨烯)/MnO_2/M复合泡沫。采用环境测试反应舱模拟含NO_x气体对环境的污染,并考察了复合泡沫在不同温度、不同MnO_2掺量时对NO_x气体的吸附降解效果。研究结果表明:与空白M泡沫相比,复合泡沫对NO_x的处理效率明显提升;当m(MnO_2)=0.02 g、温度为200℃时,复合泡沫对NO_x具有较好的处理能力,并且复合泡沫经重复多次使用后仍保持较好的吸附催化活性。
Graphene oxide（GO）have the abundant surface functional group,the 3D rGO（graphene）/MnO_2/M（melamine）composite foam was prepared when M foam was used as carrier,and the GO was bonded to the Mfoam skeleton containing MnO_2 by cooperation with chemical bonds and template method. The pollution of gascontaining NO_xon environment was simulated by environmental test reaction tank,and the adsorption-degradationeffect of composite foam on NO_xgas was investigated at different temperatures or different MnO_2 contents. Theresearch results showed that the compared with blank M foam,the treating efficiency of composite foam on NO_xwasobviously improved. The composite foam had the better ability of treating NO_x,and could still keep the betteradsorption and catalytic activity after many times reuse when MnO_2 content was 0.02 g,temperature was 200 ℃.
