We are interested in the study of facile, green and sustainable methods for the fabrication of electrochemical catalysts and systems. We have recently done work on the fabrication of noble metal deposited graphite for applications in oxygen evolution reactions (OER), ethanol oxidation and capacitor electrodes. Our method of reducing metal nanoparticles from metal ions by graphite is exceedingly simple as it only requires a (i) solution immersion step and (ii) a metal salt as the solution. Large amounts of metal nanoparticles can be generated on the surface and also withing the bulk of the graphite, up to 100 μm. 1

Excellent electrochemical catalytic performance for ethanol oxidation, OER and capacitance are shown:

We are also interested in the development of novel nanowire-based electrochemical catalytic materials. We have also worked on gold-polypyrrole core-shell nanowire and graphite-aligned Ni/Ni(OH)2 nanowires for applications as supercapacitors and catalysts, and so on. 2, 3
