A catalyst for synthesizing hydrogen peroxide is provided. The catalyst includes first material capable of dissociating hydrogen molecules; and second material capable of suppressing dissociation of oxygen molecules, where one or more interfaces are formed between the first material and the second material. The catalyst can be used as an alternative to the expensive palladium catalysts. In particular, the catalyst can be used for the direct synthesis of hydrogen peroxide.

An integrated process for making propene oxide and an alkyl tert-butyl ether comprises dehydrogenating a feed stream comprising iso-butane to provide a stream comprising iso-butene and hydrogen and separating this stream into a stream consisting essentially of hydrogen and a stream comprising iso-butene; reacting a part or all of the stream comprising iso-butene with an alkanol in the presence of a solid acid catalyst to provide an alkyl tert-butyl ether; reacting a part or all of the stream consisting essentially of hydrogen with oxygen, providing a stream comprising hydrogen peroxide; and reacting a part or all of the stream comprising hydrogen peroxide with propene in the presence of an epoxidation catalyst to provide propene oxide.
