ABSTRACT
The catalytic oxidations of small inorganic molecules such as H2 and CO occurring without formation of any side products are considered to belong to the simples t catalytic reactions and were applied by numerous authors as the catalytic test reactions carried out in order to characterize various catalysts, metallic as well as the nonmetallic. However, the simplicity of such reactions is only apparent and establishing of their unambiguous reaction paths encountered frequently serious difficulties.
