- Novel electrocatalyst of Pd/HNGF for methanol electro-oxidation in alkaline media
- Significantly enhanced electrocatalytic performance of Pd/HNGF
- Effective effect of HNGF with Pd accounting for the improved performance
In this work, palladium (Pd) nanoparticles/three-dimensional hollow N-doped graphene frameworks (HNGF) hybrid catalysts were fabricated by using amine-functionalized poly (glycidyl methacrylate) microspheres-templated HNGF as supporting materials for Pd nanoparticles (NPs). The results demonstrate that the Pd NPs with average sizes of ~Â 5.5Â nm can be well dispersed on the surfaces of HNGF with internal circular holes of ~Â 400Â nm. The Pd/HNGF catalysts exhibit high electrocatalytic activity and durability toward methanol electro-oxidation in alkaline medium, compared to Pd/graphene and Pd/carbon.
