FIELD: chemistry.
SUBSTANCE: catalyst contains a catalytically effective amount of silver and a promoting amount of rhenium and caesium. The inhomogeneous catalyst microstructure includes silver and a rhenium-caesium intermetallic phase, wherein concentration of rhenium and caesium in the intermetallic phase is higher than the concentration of silver.
EFFECT: catalyst enables to selectively oxidise ethylene into ethylene oxide with molecular oxygen with high levels of conversion of ethylene and oxygen.
