We report the synthesis of multifunctional hybrids in both films and bulk form, combining electrical and ionic conductivity with porosity and catalytic activity. The hybrids are synthesized by a two-step process: (a) ice templation of an aqueous suspension comprised of Nafion, graphite oxide, and chloroplatinic acid to form a microcellular porous network and (b) mild reduction in hydrazine or monosodium citrate which leads to graphene-supported Pt nanoparticles on a Nafion scaffold.
我们报告了多功能杂化材料的薄膜和块状形式的合成，将导电性和离子导电性与多孔性和催化活性结合在一起。这些杂化物是通过两步法合成的：（a）在由 Nafion、氧化石墨和氯铂酸组成的水性悬浮液中进行冰模板化，形成微细胞多孔网络，以及（b）在肼或柠檬酸钠的温和还原作用下，导致在 Nafion 支架上负载石墨烯的 Pt 纳米颗粒。
