Novel organic–inorganic hybrid and organic-free mesoporous niobium oxophosphate synthesized in the presence of an anionic surfactant

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.
