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) has a rich surface group, melamine (M) foam as a carrier, through the chemical bonding and the template method GO bonded to MO foam skeleton containing MnO 2 to prepare three-dimensional r GO ( Graphene) / MnO 2 / M composite foam. The environmental test chamber was used to simulate the pollution of NO_x-containing gas on the environment. The effect of NO_x gas adsorption and degradation on the composite foam at different temperatures and MnO 2 contents was also investigated. The results show that compared with the blank M foam, the treatment efficiency of NO_x is obviously improved. When m (MnO_2) = 0.02 g and temperature is 200 ℃, the composite foam has better NO_x treatment ability, and the composite foam After repeated repeated use still maintain good adsorption catalytic activity.
