Dear Colleagues,

Metallic catalysts typically operate under high-pressure and high-temperature conditions, and these reactive environments may substantially influence their morphology and surface composition as well as change their reactivity. However, the current understanding of the catalytic properties of these catalysts is generally based on simplified models with a static surface, where the structural dynamics of interfaces with liquid or gas are neglected and possible modifications during the reaction are not taken into account. This serious drawback may prevent a reliable description of catalysts’ reactivity, which mainly depends on the configuration of the surface. Today, investigating the equilibrium structure of catalysts in a reactive environment is still barely studied and remains an extremely challenging task. In this Special Issue, we want to focus on the recent experimental and theoretical works dedicated to the description and prediction of the reactivity and/or the structural dynamics of transition metal metallic catalysts under reactive environments.
