ABSTRACT:
In catalytic gas phase reactions there is used a catalyst comprising a sputtered deposit of catalytic material equivalent to between 0.5 and 5 monatomic layers upon a hard, substantially non-porous substrate. The substrate being hard and non-porous is of low surface area, that is not greater than 20 square meters per gram, and preferably comprises particles having a size in the range 0.1 micron to 0.5 centimeters.
