Hydrogen peroxide is known as a green oxidizer and utilized as a mild oxidant in many oxidation reactions.[1] It has long been recognized that quinone compounds act as working compounds, which play a pronounced role in the commercial preparation of H2O2 from H2 and O2 while present in the organic phase. The application of zeolites for the immobilization of organic and organometallic catalyst has been becoming an increasingly attractive subject in heterogeneous catalysis.[2] A few examples of H2O2 production from H2 and O2 carried out by using zeolite-supported Pd and Pd-loaded zeolite-encapsulated 2-ethylanthraquinone (EAQ) have been reported.[3,4] In this study, we present a catalytic system prepared via encapsulation of hydroquinone (HQ) and Pd nano paticles into zeolite beta, which shows high catalytic activity for the production of H2O2 from H2 and O2 under mild conditions. The beneficial cooperative effect of encapsulated HQ on the catalysis of Pd/zeolite beta can be cleared. It also gives a understanding of the reaction mechanism with encapsulated HQ inside zeolite beta by means of spectroscopic study in correlation with the catalytic results. |
