TS-1 monolithic catalysts were prepared on cordier ites b ceramics supports by dip-coating method in TS-1/H 2O suspension. The cordierites b ceramics su pports were treated with different methods, such as coated with a thin layer of sodium silicate, immersed in hydrochloric acid. The monolithic catalysts were ch aracterized by Scanning Electron Microscopy. The distribution of TS-1 Catalysts onto supported w as observed. The immobilized stability of TS-1 monolithic catalysts was evaluated by ultrasonic cl eaning and washing out experiment. TS-1 catalysts were uniformly deposited onto inner smoothed surfac e of cordierites b ceramics supports, which ware coated sodium silicate film. And experim ent data proved that TS-1 catalysts may be firmly immobilized onto supports coated sodium sili cate. Introduction Titanium silicate-1 (TS-1
