Abstract: Disclosed are a spherical titanium silicalite catalyst and a preparation method therefor. The spherical titanium silicalite catalyst has the following composition: xTiO2·(1−x)SiO2/yMPO4, wherein x is equal to 0.0005-0.04, y is equal to 0.005-0.20, M is a metal element selected from alkaline earth metals, transition metals or combinations of two or more thereof. The spherical titanium silicalite catalyst is prepared by the following method: (i) providing titanium silicalite raw powder with the composition of xTiO2·(1−x)SiO2, wherein x is equal to 0.0005-0.04, and y is equal to 0.005-0.20; (ii) mixing silica sol, an organic template agent and phosphate in proportion to obtain an adhesive; and (iii) mixing the adhesive with the titanium silicalite raw powder, and carrying out spray-drying molding and firing to obtain the titanium silicalite catalyst.
