Method of using biopolymer to synthesize titanium-containing silicon oxide material and applications thereof

A method for fabricating epoxide, comprising steps:

• mixing a titanium source, a silicon source, an acid source, a base source, a biopolymer, and a solvent to form an aqueous solution;
• letting said aqueous solution react to form a first resultant liquid, aging said first resultant liquid to form a second resultant liquid, performing a solid-liquid separation process on said second resultant liquid, and drying a solid obtained from said solid-liquid separation process to obtain a dried solid;
• performing a calcination process on said dried solid to obtain a titanium-containing silicon oxide material or performing an extraction process on said dried solid with an extracting agent to obtain a titanium-containing silicon oxide material, wherein said titanium-containing silicon oxide material meets following conditions:
• pores of said titanium-containing silicon oxide material have an average diameter of greater than 10 Å;
• more than 90% of total volume of said pores of said titanium-containing silicon oxide material have diameters of 5-200 Å;
• and
• said titanium-containing silicon oxide material has a specific pore volume of more than 0.2 cm3/g;
• and
• providing said titanium-containing silicon oxide material as a catalyst to enable a reaction of an olefin and an oxide to faun an epoxide,
• wherein said biopolymer is selected from a group consisting of chitosan, collagen, gelatin, agarose, polyhydroxyalkanoates, pullulan, starch, hyaluronic acid, and combinations thereof.
