Influence surface segregation on catalytic activity of system Zr-V-H at the oxidative dehydrogenation of aliphatic alcohols

In this article was investigated catalytic activity of system Zr-V-H at the oxidative dehydrogenation of aliphatic alcohols and was studied influence of surface composition from condition treatments in their catalytic properties. It was displayed that formation surface activity of studied system is connected to condition treatment (time, temperature, environment). It is supposed, the activity of system ZrV2 and ZrVH changes with, the alter correlation of components surface layer. The method of RFBS proved, that temperature of oxidation and duration of reductional treatments had more influence on valency condition that on composition of surface layer. It was established that the activity of studied system depend from contents of vanadium in transition degree of oxidation
