The use of chemical and structural properties of swelling clays intercalated with inorganic polymers allows the development of materials with high reactivity and potential for technological and environmental applications. This technique is known as pillaring and has been studied widely in the field of chemical and material science, but the use of pillared clays for environmental application has increased only in the last few years. Nevertheless, only a fraction of this knowledge is applied by soil scientists being, therefore, an opportunity to develop new studies including a wide range of disciplines, such as physico-chemistry and microbiology. Therefore, this review presents and discusses what are pillaring and pillared clays, methods of synthesis and some applications in soil and environmental science, aiming to encourage more research groups in Brazil to explore it.
