Pillaring of Layered Tetravalent Metal Phosphates and Oxides Using (3-Aminopropyl)trimethoxysilane Academic Article uri icon


  • (3-Aminopropyl)trimethoxysilane, (CH3O)3Si(CH2)3NH2, has been intercalated into a series of tetravalent metal phosphates of the general formula M(HPO4)2H2O (M = Zr, Ti, Sn) and a potassium tetratitanate, K2Ti4O9xH2O, to give a new range of compounds with greatly expanded interlayer distances. Calcination of these intercalates in air led to the formation of nonporous and microporous silica-pillared materials with interlayer distances between 11 and 21 and BET surface areas ranging from 29 to 232 m2g1. 1994, American Chemical Society.
