METHOD FOR PREPARING PALLADIUM CATALYST SUPPORTED ON SULFONIC ACID-FUNCTIONALIZED MESOPOROUS SILICA AND A METHOD FOR PREPARING HYDROGEN PEROXIDE USING THE CATALYST, CAPABLE OF IMPROVING THE EFFICIENCY OF A HYDROGEN PEROXIDE PREPARING PROCESS

摘要

PURPOSE: A method for preparing palladium catalyst supported on sulfonic acid-functionalized mesoporous silica and a method for preparing hydrogen peroxide using the catalyst are provided to improve the selectivity and the yield of hydrogen peroxide by minimizing the amount of additives including acid and halogen ions.;CONSTITUTION: Sulfonic acid group is introduced into mesoporous silica based on a grafting method. Palladium catalyst prepares hydrogen peroxide based on hydrogen and oxygen using sulfonic acid-functionalized mesoporoous silica as a carrier. The use amount of palladium catalyst is 0.5 to 3.5 weight%, based on the entire weight of a reaction solvent. The reaction solvent is water, methanol, or ethanol.;COPYRIGHT KIPO 2011
