    摘要: A titanosilicate catalyst and method for preparing the same, comprising primary titanosilicate particles which are combined with one another, wherein the titanosilicate catalyst comprises pores having a pore diameter of from 50 to 300 .ANG.. The inventive catalyst exhibits activity in a hydroxylation reaction of an aromatic compound, or an epoxidation reaction of an olefin, or an ammoximation reaction of a ketone using hydrogen peroxide as an oxidant.
