通过PdCl 42-与氧化石墨烯（GO）的氧化还原反应，成功制备了单分散在GO表面的超细Pd纳米粒子。由于不含表面活性剂的形成过程，制成的催化剂非常“清洁”，使其在甲酸和乙醇氧化中表现出相对于商业Pd/C催化剂的高电催化能力。这种简单直接的方法对于在合适的载体上制备高催化活性的纳米金属催化剂具有重要意义。
Ultrafine Pd nanoparticles monodispersed on graphene oxide (GO) surfaces were successfully prepared by the redox reaction between PdCl42- 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.
