The influence of particle size on the reduction of oxygen on supported platinum (Pt) electrocatalysts (Pt on carbon black) in phosphoric acid was investigated. The results confirm earlier evidence that indicates the mass activity (A g-' Pt) and specific activity bA cmm2 Pt) of Pt at 900 mV (us rhe)
An exptimental program was conducted ta determine the catalytic activity of platinum supported on carbon for the electrochemical reduction of oxygen in phosphoric acid as a function of temperature and electrolyte concentration. The Tafel slope was found to be approximately equal to 2.3 RT/F and inde
Mesoporous Pt nanosponges of high activity were successfully synthesized for the oxygen reduction reaction (ORR). These porous nanosponges of 48.7, 53.7, 62.8, and 77 nm in size were synthesized by changing the concentration of polyvinylpyrrolidone electrolyte in the electrochemical synthesis. The e
