The method needn't use a template but directly use an amorphous silicon dioxide and a titanium source as the reactants. The reactants are mixed with a solvent and react in the solvent. The suspension generated by the reaction is processed by solid-liquid separation, flushing and drying to obtain a titanium-containing silicon oxide material. The method features a simplified fabrication process and a low fabrication cost. The titanium-containing silicon oxide material fabricated by the method has a superior catalytic activity, able to catalyze an epoxidation reaction of an olefin-group compound to generate an epoxide. ## Claims ### Claim 1 A method for fabricating a titanium-containing silicon oxide material, comprising steps: preparing a mixture liquid containing an amorphous silicon dioxide, a titanium source and a solvent; enabling a reaction of said mixture liquid, and undertaking a solid-liquid separation process; and drying a solid-state material obtained in said solid-liquid separation process to obtain a titanium-containing silicon oxide material, wherein in an anhydrous state, said titanium-containing silicon oxide material is expressed by Formula (I): xTiO2(1−x)SiO2 (I) wherein x is a number within 0.002-0.2. ### Claim 2 (depends on 1) The method according to claim 1, wherein said amorphous silicon dioxide is smoked silica, fumed silica, silica gel, or silica sol; said titanium source is a titanate or an inorganic titanium source; said solvent is an alcohol-group compound. ### Claim 3 (depends on 2) The method according to claim 2, wherein said titanate is selected from a group consisting of tetramethyl titanate, tetraethyl titanate, tetrapropyl orthotitanate, tetra isopropyl titanate, tetrabutyl orthotitanate, tetra sec-butyl titanate, tetrabutyl isotitanate, tetra tert-butyl titanate, and combinations thereof; said inorganic titanium source is titanium trichloride or titanium tetrachloride; said solvent is selected from a group including methyl alcohol, ethyl alcohol, isopropyl alcohol, butyl alcohol, and tert-butyl alcohol. ### Claim 4 (depends on 1) The method according to claim 1, wherein a molar ratio of titanium to silicon ranges from 0.002 to 0.2. ### Claim 5 (depends on 4) The method according to claim 4, wherein a molar ratio of titanium to silicon ranges from 0.01 to 0.1. ### Claim 6 (depends on 1) The method according to claim 1, wherein said reaction of said mixture liquid is undertaken at a temperature of 20-100° C. for 0.5-3 hours; said solid-state material obtained in said solid-liquid separation process is persistently dried at a temperature of 30-120° C. for 0.5-6 hours. ### Claim 7 (depends on 1) The method according to claim 1 further comprising at least one of following steps: calcining said titanium-containing silicon oxide material at a temperature of 300-800° C. for 1-9 hours; silylating said titanium-containing silicon oxide material at a temperature of 25-200° C. for 0.5-3 hours; and incorporating a transition metal into said titanium-containing silicon oxide material, wherein a concentration of said transition metal in said titanium-containing silicon oxide material is within 0.01-10 wt %. ### Claim 8 (depends on 7) The method according to claim 7, wherein said concentration of said transition metal in said titanium-containing silicon oxide material is within 0.05-5 wt %. ### Claim 9 (depends on 1) A method for fabricating an epoxide, comprising a steps: providing said titanium-containing silicon oxide material fabricated according to claim 1 as a catalyst to enable a reaction of an olefin-group compound and an oxide to form an epoxide. ### Claim 10 (depends on 9) The method according to claim 9, wherein said olefin-group compound is a mono-olefin compound, a di-olefin compound, or a poly-olefin compound; said oxide is an organic peroxide or a hydroperoxide. ### Claim 11 (depends on 10) The method according to claim 10, wherein said mono-olefin compound is selected from a group consisting of ethylene, propylene, 1-butene, isobutene, 1-hexene, 2-hexene, 3-hexene, 1-octene, 1-decene, styrene, and cyclohexene; said di-olefin compound is butadiene or isoprene; said organic peroxide is ethylbenzene hydroperoxide, cumene hydroperoxide, tertiary butyl hydroperoxide, or cyclohexyl hydroperoxide ### Claim 12 (depends on 9) The method according to claim 9, wherein a molar ratio of said olefin-group compound to said oxide ranges from 1:100 to 100:1. ### Claim 13 (depends on 12) The method according to claim 12, wherein said molar ratio of said olefin-group compound to said oxide ranges from 1:10 to 10:1. ### Claim 14 (depends on 9) The method according to claim 9, wherein said reaction of said olefin-group compound and said oxide is undertaken for 1 minute-48 hours at a temperature of 0-200° C. and at a pressure of 1-100 atm. ### Claim 15 (depends on 14) The method according to claim 14, wherein said reaction of said olefin-group compound and said oxide is undertaken for 5 minute-8 hours at a temperature of 25-150° C. and at a pressure of 1-100 atm.
