Ultrafine Pd nanoparticles monodispersed on graphene oxide (GO) surfaces were successfully prepared by the redox reaction between PdCl(4)(2-) and GO. The as-made catalyst is very "clean" as a result of the surfactant-free formation process, allowing it to express high electrocatalytic ability in formic acid and ethanol oxidation relative to a commercial Pd/C catalyst. This simple and straightforward method is of significance for the facile preparation metal nanocatalysts with high catalytic activity on proper supporting materials.
在氧化石墨烯（GO）表面上成功制备了单分散的超细 Pd 纳米粒子，这是通过 PdCl(4)(2-)和 GO 之间的氧化还原反应实现的。由于无表面活性剂的形成过程，所制备的催化剂非常“清洁”，相对于商业 Pd/C 催化剂，它在甲酸和乙醇氧化中表现出高电催化能力。这种简单直接的方法对于在适当的支撑材料上制备具有高催化活性的金属纳米催化剂具有重要意义。
