Surface Area Measurement by Chemisorption of Gases on Vaccum Evaporated thin Film of Platinum-Tungsten Film

[摘要] The chemisorption of hydrogen and carbon monoxide, as well as the hydrogen titration of prechemisorbed oxygen was studied at 110¡É on evaporated platinum and platinum-tungsten films. The results suggest that hydrogen titration of prechemisorbed oxygen may be used to determine the platinum surface area of platinum-tungsten film.
