Temperature-programmed desorption of hydrogen from Rh/C catalysts

  • W. K. Jóźwiak
Article

Abstract

A strong temperature-activated character of hydrogen adsorption on the surface of Rh/C catalyst has been found, especially in relation to high-temperature form. The unreactivity of this form toward oxygen at room temperature suggests that its source is the carbon surface.

Abstract

Найден сильный температурно-активирующий характер адсорбции водорода на поверхности катализатора Rh/C, особенно в случае высокотемпературных форм. Неактивность этой формы по отношению к кислороду при комнатной температуре объясняют углеродной формой поверхности.
