摘要：
Pt/gamma-Al2O3 catalysts made by fast and simple electrochemical dispersion method were characterized using X-ray absorption spectroscopy, CO chemisorption, transmission electron microscopy and X-ray diffraction, and compared with an impregnated catalyst with respect to oxidation of CO and NO. A combination of techniques revealed average particle sizes of 3-4 nm for 0.81-3.8 wt% Pt/gamma-Al2O3 catalysts. Electrochemically prepared materials demonstrated catalytic activity comparable to that of conventional impregnated catalyst and reasonable stability. [GRAPHICS]
