Abstract

The chemisorption of hydrogen and carbon monoxide, as well as the hydrogen titration of prechemisorbed oxygen was studied at $110^{\circ}$C 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.

백금 백금-텅스텐 증착막에 의한 수소, 일산화탄소의 화학흡착과 화학흡착시킨 산소의 수소 titration을 $110^{\circ}$C에서 실험해본 결과, $H_2/O_2$ titration 방법에 의한 백금-텅스텐 증착막에서의 백금 표면적 측정이 가능한 것 같다.
