Since the development of nanoscience and nanotechnology, the ability to create controlled structures and geometries has provided means to investigate and optimize a broad range of catalytic processes. The compositional and structural complexity of these catalysts allows tuning the chemical and adsorption properties in order to optimize their performance for specific reactions.

In electrocatalysis, the use of shape-controlled metal nanoparticles has produced not only a clear improvement in the electrocatalytic activity of different reactions of interest but also a clear understanding of the effect of the surface orientation of nanostructured materials. The shape of a nanoparticle anticipates the coordination of the atoms at the surface due to the intrinsic correlation between the shape and the surface structure (atomic arrangement of the surface) of a nanoparticle.

In this context, several shaped nanoparticles are being successfully implemented in different reactions (electrooxidation of formic acid, methanol and ethanol and oxygen reduction, water splitting, electrochemical reduction of CO2), relevant for applications ranging from low-temperature fuel cells, energy storage, and selective removal and/or generation of chemicals, among many others.

The aim of this Research Topic is to cover recent developments in the synthesis of novel shape-controlled nanoparticles including metals, alloys, core-shell, metal oxides, metal sulphides, etc, and their application to electrocatalytic reactions. We welcome your submission of original research articles, reviews, and mini-reviews to this Research Topic.
