Claim:
1. A method of surface modification of alumina, the method comprising: 1) dissolving a soluble kazoe in deionized water to yield a kazoe aqueous solution; 2) submerging an alumina carrier in the kazoe aqueous solution and drying the alumina carrier in a vacuum environment; 3) placing the dried alumina carrier in a reactor, adding silicon tetrachloride and Grignard reagent dropwise to the reactor, sealing and heating the reactor to a constant temperature, and maintaining the constant temperature for between 3 and 18 hours, wherein a volume ratio of the added silicon tetrachloride and the alumina carrier is between 0.5:1 and 5:1, the constant temperature is controlled to be between 160 and 350° C.; and 4) cooling the reactor, filtering, washing, and drying the alumina carrier in the vacuum environment, whereby obtaining a surface modified alumina carrier.
