Abstract

SHS investigation development is considered from the geographical and historical viewpoint. 3 stages are described. Within Stage 1 the work was carried out in the Department of the Institute of Chemical Physics in Chernogolovka where the scientific discovery had been made. At Stage 2 the interest to SHS arose in different cities and towns of the former USSR. Within Stage 3 SHS entered the international scene. Now SHS processes and products are being studied in more than 50 countries.

Abstract

Hydrotalcites (HT) and hydrotalcite-based materials are viewed as attractive and feasible choices among heterogeneous catalysts, particularly in organic catalytic transformations. These catalysts have been widely researched as promising candidates in one-pot organic synthesis. They are synthesised via the standard co-precipitation method and can be used as support for transition metals and nanomaterials. Compared to the corrosive, hard to reutilise and, detrimental to the environment homogenous catalysts, HTs are high-functioning alternatives that deliver several benefits like profitable yields, recyclability and excellent selectivity. They are being studied today as precursors for a variety of scientific purposes such as in the production of renewable fuels, polymers, olefins and pharmaceuticals. Such processes involve essential organic reactions like isomerisation, oxidation, hydrogenation, methanation, nucleophilic additions, transesterification, and many more. In this chapter, examples of such organic reactions where hydrotalcite-based materials posed as an optimal catalyst are discussed.
