Thiol-functionalized porous clay heterostructures (PCHs) have been prepared by intragallery assembly of mesoporous organosilica in natural smectite clay. The mesoporous framework was formed by surfactant-directed co-condensation of tetraethoxysilane (TEOS) and 3-mercaptopropyltrimethoxysilane (MPTMS...
