In this work, the low-loading (3 wt%) palladium/graphene oxide (Pd/GO) aerogels are facilely prepared via the lyophilisation, vacuum and reduction treatments. The Pd/GO aerogels display enhanced activity and stability in comparison to the commercial Pd/C. The enhancement of electrocatalytic performance can be attributed to the functional groups on the surfaces of the GO support, such as carbonyl and carboxyl groups, which can be tuned to interact with palladium to form active phases for the reaction. In addition, Pd nanoparticles (NPs) remain dispersed in nanoscale on the reacted catalyst.

高活性钯/氧化石墨烯气凝胶催化剂上的乙醇电氧化

在这项工作中，通过冻干，真空和还原处理可轻松制备低负荷（3 wt％）的钯/氧化石墨烯（Pd / GO）气凝胶。与商用Pd / C相比，Pd / GO气凝胶显示出增强的活性和稳定性。电催化性能的提高可以归因于GO载体表面上的官能团，例如羰基和羧基，可以将其调整为与钯相互作用以形成反应的活性相。此外，Pd纳米颗粒（NPs）仍以纳米级分散在已反应的催化剂上。
