Effects of calcination temperature on organic functional groups of TiO2 and the adsorption performance of the TiO2 for methylene blue

ABSTRACTHerein, TiO2 was prepared by the hydrolysis method in critic acid (with both carboxyl and hydroxyl groups) solution firstly. And then, the as-prepared TiO2 was calcined at 50, 150, 250, 350...
