structure can be controlled at the atomic scale by manipulating kinetics to realise
significant reactivity gains.
Research into metal-on-metal growth and the resulting interfacial structures in
bimetallic nanoparticles is still rather limited. The nature of interfacial structures
impacts directly on reactivity. This review has shown that by taking a combined
approach of experimental structural characterisation of interfacial structures, com-
puter simulation of metal-on-metal growth and controlled sample synthesis to
manipulate interfacial structure, alongside catalytic reactivity measurements, it is
possible to make substantial steps towards the ultimate goal of the rational design of
bimetallic nanocatalysts.
