In the convemional synthesis of pillared clay (PILC), the first step is to prepare the pillaring agents containing polymer hydroxy cations complex with stable structure. When pillaring agents are mixed with clay suspension, the cations exchange into the interlayers of the clay, prop layers of the clay as the pillars to form regular pore structure of PILC after In the convemional synthesis of pillared clay (PILC), the first step is to prepare the pillaring agents containing polymer hydroxy cations complex with stable structure.
