Composition control of alloy nanoparticles consisting of bulk-immiscible Au and Rh metals via an ionic liquid/metal sputtering technique for improving their electrocatalytic activity

AuRh bimetallic alloy nanoparticles (NPs) were successfully prepared by simultaneous sputtering of Au and Rh in a room-temperature ionic liquid (RTIL) of N , N -diethyl- N -methyl- N -(2-methoxyethyl) ammonium tetrafluoroborate (DEME-BF 4 ). Bimetallic AuRh alloy NPs of 1–2 nm in size were formed in...
