Surface Engineering for Chemical Activity

The chemical process being catalyzed should have a high productivity within a specified reactor volume with high reaction rates for the desired reactions and low rates for undesired reaction pathways. This article reviews the general catalyst preparation procedures, namely, impregnation, ion exchange, and precipitation. Catalyst carriers are usually high-surface-area inorganic materials with complex pore structures, into which catalytic materials such as palladium, platinum, cobalt, chromium oxide, and vanadium pentoxide are deposited using these procedures. The article also provides information on catalyst powder processing.
