Summary:Porous heterostructured clays - PCHs - are lamellar solids with acid and adsorptive properties serving as catalysts or catalyst supports formed on a template mechanism. This work provides information about porous heterostructured clays. Historical aspects of the development of lamellar solids to porous heterostructured clays will be discussed, and detailed information on synthesis and applicationaspects, as well as on the influence of eachreagent on these materials and the characterization techniques used to prove their formation will be given. Argilas porosas heteroestruturadas - PCHs - são sólidos lamelares com propriedades ácidas e adsortivas que servem de catalisadores ou suporte de catalisadores formados pelo mecanismo de gabarito. O presente trabalho traz informações sobre as argilas porosas heteroestruturadas - PCHs. Aspectos históricos sobre o desenvolvimento dos materiais lamelares até os PCHs são abordados, bem como informações detalhadas sobre aspectos de síntese, aplicações, a influência de cada reagente na formação destes materiais e as técnicas de caracterização essenciais utilizadas para comprovar a sua formação.
