|Title:||Pd nanoparticle decollated reduced graphene oxide and PdSn nanoparticles synthesized by stepwised electroless deposition for oxygen reduction reaction catalysts||Authors:||Ang, Kenneth Boon Khim||Keywords:||DRNTU::Engineering||Issue Date:||2014||Abstract:||The platinum (Pt) catalyst that is commonly used in fuel cells due to its high catalytic activity is expensive and depleting in supply. Hence, the focus has shifted to non-platinum catalysts such as palladium-based ones with similar electrochemical activity. Current synthesis methods involve a substantial amount of time and harsh conditions. This final year project reports a facile and quick stepwise electroless deposition process to synthesize palladium (Pd) nanoparticles on the surface of a rotating disk electrode. The catalysts were then characterized by transmission electron microscopy (TEM), electron diffraction, X-ray diffraction (XRD) and electrochemical measurements. The results show that bimetallic Pd-Sn catalyst has not been synthesized successfully in acidic medium while Pd nanoparticles decorated on reduced graphene oxide exhibit better catalytic activity compared to Pt/C and Pd/C in alkaline medium.||URI:||http://hdl.handle.net/10356/61354||Rights:||Nanyang Technological University||Fulltext Permission:||restricted||Fulltext Availability:||With Fulltext|
