Abstract:Keggin-structured 12-tungstophosphoric acids were immobilized onto the surface of amine-modified mesoporous sieve SBA-15 as onium salts. All the catalyst materials were characterized by X-ray diffraction,N2 physisorption,Fourier transform infrared spectroscopy,thermal gravimetric analysis,and X-ray photoelectron spectroscopy for their structural integrity and physicochemical properties. Characteri-zation of the catalysts confirmed an ordered hexagonal mesostructure for SBA-15 and that the Keggin structure o...
