Using composite template (CTAB and P123) as structuredirecting agents, industrial titanyl sulfate as Ti source, the precursor of mesoporous TiO2 was prepared via controlling the hydrolysis and condensation rate of industrial TiOSO4, self-assembly rate of template and pH value of solution. The asprepared materials were characterized by XRD, HRTEM, SAED and nitrogen adsorptiondesorption.Ordered mesoporous anatase titania is obtained after template removal, with hexaganol mesopore, SBET of 205.7m2/g,average pore diameter of 3.28nm. The formatiom process of mesopore belongs to cooperative formation mechanism, i.e. the hydrolysis colloid particles of titanium and composite template interact through static force and hydrogen bond on the interface, cooperating to form mesopore.
