Nanostructured catalytic membrane reactors of the new generation
Studied in this work were the industrially important processes (partial oxidation of methane, oxidation of methanol to formaldehyde, reduction of oxygen in aqueous media, oxidation of CO to CO2) involving the use of nanostructured catalytic membrane reactors of the new generation. The membrane reactors were prepared according to various methods: sol-gel, molecular layering, magnetron sputtering, chemical deposition, etc. Subject to study were also the structure of the catalytic membranes and the kinetics of the reactions occurring in the gaseous and liquid phases. It was demonstrated that the deposition of a nanostructured catalytic layer to nonselective porous membranes could give rise to, or enhance, the selectivity of both their gas permeability and catalytic activity. In the case of the application of hybrid membranes, an “asymmetry effect” was discovered and explained. Some of the membranes studied can be considered as specific nanoreactors.
