A simple microwave method was successfully adopted for the synthesis of various amount of Ti loaded TUD type mesoporous silica (Ti-TUD-1) using triethanolamine (TEA) as both templating and chelating agent. The time-cost was reduced dramatically due to the microwave heating which could accelerate the atrane formation as well as their following hydrolysis and condensation steps. Three dimensional mesopore structures were obtained with narrowed pore size distribution (2-8 nm) and high surface area (700-1000 m(2)/g). Ti species incorporated as tetrahedral structure were active in the liquid phase oxidation of cycloolefins. Further, microwave synthesis brought the hydrophobic nature to Ti-TUD-1 which could be attributed to the improved catalytic activity compared to conventionally prepared catalysts.
