This chapter makes a comprehensive and critical overview on the preparation of hectorite-like solids, pillaring, properties and catalytic applications of pillared interlayered synthetic hectorite clays (PILCs). Hectorite, with some specific properties, is a natural mineral among the most common smectite group of clay minerals. However, hectorite in natural occurrence is scarce. The general synthesis of hectorite-like solids is by means of hydrothermal process or solid-state reaction. The synthesis variables, crystallization, structure of synthetic hectorite along with their characteristics are discussed. Using synthetic hectorite clays with tuneable composition and high purity as layered host precursors is much conducive to designed features and specific applications of PILCs, in contrast to using natural clay minerals with impurities plus other uncertain factors arising from natural deposits. The various intercalation methods and intercalated species in PILC products have been reported with an objective to improve the porous structure and properties of the resultant PILCs. Among many potential uses of pillared synthetic hectorite, the important applications concerning catalysis are emphasized. Finally, the prospects of synthetic hectorite-based materials are briefly remarked.
