摘要: A new solid acid catalyst, SO 4 2−/TiO 2 modified with tin, was prepared using a sol-gel method and its physicochemical properties were revealed by nitrogen adsorption-desorption, X-ray powder diffraction, scanning electron microscopy, Fourier transform infrared spectroscopy, infrared spectroscopy of adsorbed pyridine, temperature-programmed desorption of ammonia and thermal gravimetric analysis. The structure, acidity and thermal stability of the SO 4 2−/TiO 2-SnO 2 catalyst were studied. Incorporating tin …
