ABSTRACT
This chapter lists out different factors based on which the heterogeneous catalysis is drawn. Almost any important organic reaction can be elected for catalysis that will make the reaction conditions milder, that will increase the conversion and the yield, and that will drive the selectivity up to the enzymatic dreamland of specificity. Clay minerals are inorganic polymers. The component layers are tetrahedral and octahedral. In the presence of catalysts such as aluminium chloride and inorganic solids, sulfuryl chloride chlorinates aromatic hydrocarbons, with evolution of sulfur dioxide and of hydrogen chloride. Very many minerals exist in nature, with structures and topologies (fibers, tubes, sheets, etc.) that make them appealing to the chemist to devise suitable modifications of these surfaces to make them apt for impressive results as catalysts. A knowledge of the standard reaction mechanism under homogeneous reaction conditions is translatable to rational design of catalysts.
