Issue Date: | 2004 | Citation: | Chen, W.-X.,Lee, J.-Y.,Liu, Z.-L. (2004). Carbon supported Pt nanoparticles prepared by microwave heating and their electrocatalytic activities for methanol oxidation. Acta Chimica Sinica 62 (1) : 42-46. ScholarBank@NUS Repository. | Abstract: | Carbon supported platinum nanoparticles were prepared by rapid microwave (MW) heating of ethylene glycol solutions of H2PtCl6 in the presence of XC-72 carbon. The Pt loading was varied in the range of w = 10%-20%. It was found that Pt nanoparticles have uniform shape and size with an average diameter of 3.6 nm, which could exist in high dispersion on the XC-72 carbon surface. Electrochemical measurements showed that the microwave-prepared Pt/C catalyst exhibited higher electrocatalytic activity in methanol, oxidation than Pt/C catalyst prepared by using KBH4 as the reducing agent or commercial E-TEK Pt/C catalyst. | Source Title: | Acta Chimica Sinica | URI: | http://scholarbank.nus.edu.sg/handle/10635/88612 | ISSN: | 05677351 |
