Abstract
NaY Zeolite has been selected as a suitable material to host 1.5 wt% Platinum (Pt) loading on zeolite using ion exchange methods of Pt(NH3)4(NO3)2 without excess NH4NO3 nitrate and Pt(NH3)4(NO3)2 with excess NH4NO3 nitrate. The structure/reactivity relationship of Pt nanoparticle was experimentally studied via Nafion@ bound electrodes to investigate the interaction nature of Pt with zeolite and electron transfer. By using extended X-ray adsorption fine structure technique, Pt particle size was predicted as 0.7 – 1.5 nm. It was found Pt oxides could be electrochemically reduced via a hydrogen ‘spillover’ phenomenon. A highly dispersed small Pt particle distribution can be achieved with excessive H+ ions on zeolite acidic sites.
