Using functional materials to stabilize emulsions of carbon dioxide (CO) and water is a promising way to expand the utility of CO and functional materials. Here we demonstrate for the first time that the partially reduced graphene oxide (rGO) can well stabilize the emulsion of CO and water without the aid of any additional emulsifier or surface modification for rGO. More interestingly, such a novel kind of emulsion provides a facile and versatile route for constructing highly porous three-dimensional rGO materials, including rGO, metal/rGO, and metal oxide/rGO networks. The as-synthesized Au/rGO composite is highly active in catalyzing 4-nitrophenol reduction and styrene epoxidation.
使用功能材料稳定二氧化碳（CO）和水的乳液是扩大 CO 和功能材料用途的一种很有前途的方法。在这里，我们首次证明部分还原氧化石墨烯（rGO）可以在不添加任何额外乳化剂或表面修饰 rGO 的情况下很好地稳定 CO 和水的乳液。更有趣的是，这种新型乳液为构建高度多孔的三维 rGO 材料提供了一种简单而通用的途径，包括 rGO、金属/rGO 和金属氧化物/rGO 网络。所合成的 Au/rGO 复合材料在催化 4-硝基苯酚还原和苯乙烯环氧化反应中具有很高的活性。
