The invention describes catalysts, methods of making catalysts, methods of making a microchannel reactor, and methods of conducting chemical reactions. It has been discovered that superior performance can be obtained from a catalyst formed by directly depositing a catalytic material onto a (low surface area) thermally-grown alumina layer. Improved methods of conducting oxidative dehydrogenations are also described.
