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

1-10. (canceled)
An H2O2 formation catalyst comprising particles of metal selected from the group consisting of gold, palladium and combinations of gold and palladium, deposited on a support which has been acid washed prior to metal deposition.
A method of manufacturing a catalyst, comprising acid washing a catalyst support, depositing a precursor of at least one of gold and palladium onto the acid washed support to form a catalyst precursor and subsequently calcining the catalyst precursor to form a catalyst comprising particles of at least one of gold and palladium deposited on said support.
A process for the formation of H2O2 comprising directly reacting oxygen and hydrogen in the presence of a reaction medium and in the presence of a catalyst comprising particles of metal selected from the group consisting of gold, palladium and combinations of gold and palladium, deposited on a support which has been acid washed prior to metal deposition.
