The invention discloses a titanium dioxide supported catalyst for foul VOCs purification in the grain and oil processing industry and a preparation method thereof.The titanium dioxide supported catalyst comprises a titanium dioxide carrier and active components evenly supported on the titanium dioxide carrier, and the titanium dioxide carrier is in a bird nest shape and is formed by assembling TiO2 nanowires; the active component is selected from one or more of copper oxide, cerium oxide and manganese oxide. According to the titanium dioxide supported catalyst disclosed by the invention, titanium dioxide with novel bird nest-shaped morphology is used as a carrier to support non-noble metal, the catalyst can simultaneously remove stink VOCs (Volatile Organic Compounds) such as sulfur-containing organic matters, alkanes and oxygen-containing organic matters generated in various grain and oil processing industries, the removal efficiency is high, and the catalyst can be repeatedly regenerated; the low-temperatur
