Abstract

A novel organic-inorganic hybrid mesoporous niobium oxophenylphosphate was synthesized by using supramolecular assembly of sodium dodecylsulfate molecules. X-ray diffraction, transmission electron microscopic image and N₂ adsorption data indicated the formation of a wormhole-like disordered mesostructure in the sample. The ¹³C and ³¹P MAS NMR, FTIR, UV-visible spectroscopic data and chemical analysis results indicated that all P atoms are attached to phenyl groups directly and these are combined with Nb atoms through O atoms. Calcination of this hybrid material yielded an organic-free mesoporous niobium oxophosphate material.
