The dynamic behavior of supported metal nanoparticles under reaction conditions plays a crucial role in determining their catalytic performance. Here, time-resolved XRD, PDF, and modulation techniques provide direct evidence of hydrogen-induced breathing and detachment of Pt nanoparticles from an alumina support, uncovering reversible, size-dependent dynamics in both gas and liquid phases.
