英文摘要 | a novel one-step strategy is proposed to fabricate three-dimensional (3d) graphene hydrogel (gh) by simultaneous self-assembly and reduction of graphene oxide (go) at 90 degrees c under atmospheric pressure, using l-cysteine (l-cys) as both templating and reducing agent. the preparation process can be completed within 3 h without producing any contamination, which is a fast, facile, economical and green method for the fabrication of gh. the freeze-dried product - graphene aerogel (ga) - has high mechanical strength and thermal stability, with hierarchical pore structure and large specific surface area. more importantly, the as-prepared ga exhibits outstanding adsorption capacity towards organic dyes, which could be a potential candidate for efficient adsorbents in water purification. in addition, the established method is successfully extended to the preparation of platinum nanoparticle (ptnp)-loaded 3d graphene materials via one-step simultaneous reduction and assembly of metal ions and go. the as-obtained ptnps/ga with free-standing structure can act as a heterogeneous catalyst for the chemical reduction of p-nitroaniline, which shows excellent catalytic activity. the developed method is promising for preparing other graphene-based multifunctional composite materials. |
