Catalytic materials coated on honeycomb monoliths

The ability of zirconia and modified zirconia coated on cordierite honeycomb monolith as heterogeneous solid acid-base catalysts in selected liquid/vapour phase organic reactions is explained in this book. With a high active surface area, the catalyst coated on cordierite honeycomb monolith has advantages over powder form catalyst. A very thin layer of catalysts loaded on a monolith is very effective and provides a high active surface area, safe storage and a longer life time, and environmentally friendly safe disposal, as well as easy separation and total recovery from the reaction mixture and active across a wide temperature range.However, catalyst coated cordierite honeycomb monoliths is also an interesting initiative step in the field in the field of liquid phase/vapour phase organic synthesis. Organic reactions were studied generally under conventional heating, microwave heating and comparison between the two. The influence of deviation of surface characteristics and acidity on the selectivity and activity of catalyst samples to various organic reactions were studied.
