Surface Area, Pore Size, and Particle Size Engineering of Titania with Seeding Technique and Phosphate Modification

摘要: The environmentally benign route of the organic free process was evolved in precipitating hydrated titania from titanium oxysulphate solution at 90 °C, using crystal nuclei with addition ammonia. synthesized found to be mesoporous and reactive, a BET surface area 277 m2/g. on calcination air 500 °C for 2 h produced anatase 100 as-synthesized calcined materials were characterized by X-ray diffraction, scanning electron microscopy−energy dispersive spectrometry, ultraviolet−visible/diffuse reflectance spectroscopy, inductively coupled plasma mass thermogravimetry differential thermal analysis, diffuse infrared Fourier transform nitrogen adsorption−desorption measurements. incorporation phosphorus framework inhibit crystallization particle growth enhance st...
