Summary:The invention relates to a preparation method for cubic Si-O-Ti composite particles. The preparation method comprises the following steps: firstly, adding lower alcohols of C1-C3 into inorganic strong acid, then adding silicate ester and stirring to obtain a solution A; uniformly mixing the lower alcohols of C1-C3 with titanate to form a solution B, slowly adding the solution B into the solution A and stirring for 0.5-1.5h to be uniformly, standing at the temperature of 50-70 DEG C for 6-8d to obtain an aged solution sample, wherein the mol ratio of Si to Ti is (1:5)-(1:1); and secondly, adjusting the pH value of the aged solution sample to 7-11, then adding 1.0-1.5 g of anion surfactant for violently stirring and reflowing at the temperature of 70-90 DEG C for 5-7h to obtain the cubic Si-O-Ti composite particles. The preparation method disclosed by the invention has the advantages of simple flow, simplicity and convenience in operation, low cost and low requirement on the equipment; and the Si-O-Ti composite
