Abstract
Palladium (Pd) was incorporated into TUD-1 mesoporous siliceous material by using one-pot synthesis procedure. The catalytic activity of the prepared samples was evaluated in the selective hydrogenation of 1,5-cyclooctadiene (COD) at 80 degrees C in a solvent-free condition. Pd-TUD-1 showed > 95% conversion of COD with a selectivity > 90% towards cyclooctene (COE).
