The aim of this review is offering an overview of the state-of the art of some relevant aspects about the electrocatalysis at nanoparticles by going through a broad range of different materials and electrocatalytic reactions. In particular, the two main topics reviewed here are electrocatalytic reactions affected by low-coordination surface sites including nanoparticles enclosed by high-index and low-index facets and electrocatalysis at single nanoparticles. This review covers, mainly following a chronological order in each section, the most relevant contributions on these two topics, highlighting the most interesting points of each particular approach. The reported results evidence how determining is the presence of low-coordination sites at the surface of the nanoparticles on their resulting electrocatalytic properties, as well as how beneficial can be for studying electrocatalytic reaction mechanisms the analysis of one single nanoparticle.
