Abstract

Addition of 5% Pt or alkali metals such as K or Cs each separately to the bifunctional MoO2− x (OH) y catalyst results in modification of the chemical structure of this system, especially in the case of alkali metals. A new MoO2− x (OA) y, AK, Cs, monofunctional structure having only metallic properties is formed. In the case of Cs for example, the MoOCs bond formation takes place in the course of the reduction process of MoO3 to MoO2 by hydrogen hinders ...
