Abstract

Lithium and indium doped nickel oxide samples have been prepared with up to 3 at. % of dopant. The electrical properties of these samples have been studied. All the samples exhibit p-type conductivity which increases with lithium doping and decreases upon doping with indium. Dehydrogenation of 2-propanol on these catalysts increases with the hole concentration in the solid. Desorption of acetone appears to be the rate-determining step. A possible mechanism for the reaction is proposed.

Abstract

Были приготовлены образцы окиси никеля, насышенные литием и индием, с содержанием допанта до 3 ат.%-ов. Были исследованы электрические свойства этих образцов. Для всех образцов была обнаружена проводимость типа р, которая возрастает с литиевым насыщением и уменышается с индиевым насыщением. Дегидрирование 2-пропанола на этих катаизаторах уменьшается с увеличением концетрации дырок в твердом веществе. Ступенью, лимитирующей скорость процесса, является десорбция ацетона. Предлагается вероятный менанизм протекания процесса.
