The special surface structure and distinctive quantum confinement of electrons provide two-dimensional (2D) materials with extraordinary properties. Ultrathin 2D noble-metal nanosheets consisting of single or few atomic layers, in particular, demonstrate high catalytic activities. Here, we demonstrate solid-phase synthesized ultrathin palladium (Pd) and its alloys’ nanosheets (PdFe, PdCo, and PdNi) on RGO using carbon monoxide as reducing and surface-confining agent. No templates and surfactants were used in the process, making it one of the most promising routes toward preparing such nanomaterials in large quantity and at low price. The ultrathin Pd and its alloys’ nanosheets on RGO hybrids show high catalytic activities and durability.

具有高催化活性的RGO在RGO上固相合成超薄钯及其合金纳米片

电子的特殊表面结构和独特的量子限制为二维（2D）材料提供了非凡的性能。由单个或几个原子层组成的超薄2D贵金属纳米片尤其具有高催化活性。在这里，我们演示了使用一氧化碳作为还原剂和表面限制剂，在RGO上固相合成的超薄钯（Pd）及其合金的纳米片（PdFe，PdCo和PdNi）。在该过程中未使用模板和表面活性剂，这使其成为制备大量且低成本的此类纳米材料的最有希望的途径之一。RGO杂化体上的超薄Pd及其合金纳米片表现出高催化活性和耐用性。
