NEW CATALYSTS FOR HYDROGEN PEROXIDE PRODUCTION
Lead Research Organisation:

Department Name: Chemistry
Abstract
The aim is to exploit a recent discovery concerning the production of a new high activity catalyst for use in the production of hydrogen peroxide from the direct reaction between hydrogen and oxygen using pretreated supported gold-palladium alloy catalysts. The methodology uses a pretreatement of the support which switches off the sequential decomposition of hydrogen peroxide under reaction conditions thereby enabling very high selectivities to the desired hydrogen peroxide to be achieved together with high rates of production. Initial results show the new catalyst is over six times as active as the current equivalent commercial catalyst and retains complete specificity for hydrogen peroxide formation. Funding is requested to complete patent exemplification and to ensure commercial exploitation can be achieved.

Description | A catalyst effective for the direct reaction of hydrogen and oxygen to form hydrogen peroxide comprises particles of gold, palladium or, preferably, gold and palladium deposited upon an acid- washed support. Surprisingly high selectivity to and production of hydrogen peroxide is observed, with low hydrogen peroxide decomposition. The catalysts have extended lifespan. |
