摘要
以氧化石墨(GO)为原料、铜纳米粒子为还原剂,制备得到三维还原氧化石墨烯水溶胶H;通过冷冻干燥,得到相应的还原氧化石墨烯气溶胶A。以得到的H催化还原对硝基苯酚(4-NP),结果表明,H对4-NP还原有良好的催化性能。
A simple one-step method for fabricating graphene-based hydrogels H with interconnected 3D networks induced by Cu nanoparticles was developed. During this process,graphene oxide (GO) was reduced by Cu nanoparticles to form reduced GO(rGO) that self-assembled to obtain H. The corresponding graphene-based aerogels A was fabricated from H by freeze-drying. The obtained H exhibited good catalytic performance to the reduction of 4-nitrophenol.
