This PhD thesis was initially motivated by the understanding of the peculiar electrocatalytic activity of hollow PtNi/C nanoparticles for the oxygen reduction reaction (ORR). Investigations on the formation and growth mechanism of this novel class of nanocatalysts using operando X-ray and electron-based techniques revealed that, beyond alloying effects, structural disorder is a lever to boost the ORR kinetics on bimetallic nanomaterials. The ‘defects do catalysis’ concept was progressively extended to various PtNi catalyst nanostructures, namely to advanced shape-controlled nanocatalysts from the ORR electrocatalysis landscape thanks to fruitful collaborations with European laboratories. This work shows that, through their distorted surface...
