PLATINUM NANOPARTICLES ON MICROSTRUCTURE CONTROLLABLE CARBON SUPPORTS BY PULSE-MICROWAVE ASSISTED CHEMICAL REDUCTION
Platinum nanoparticles supported on different microstructure controllable carbon supports, i.e. fish-bone carbon nanofiber and MWCNT for proton exchange membrane fuel cell (PEMFC) was prepared by a pulse-microwave assisted chemical reduction process. The effects of pH value, microwave condition as well as the carbon support microstructure on catalyst performance were investigated in this paper. The results prove that pH value, microwave condition and carbon support microstructure have significant influence on the platinum nanoparticle size and distribution, the electrochemical surface area and catalytic performance. The results reveal that the Pt Pt/MWCNT shows its highest performance with a pH value of 11.5 and a microwave irradiation time of 8s. While for Pt/f-CNFs, it is more active than other catalysts when the pH value is 10 and the microwave irradiation time is 14s.
