About this collection

Single-atom catalysts (SACs) with isolated metal atoms dispersed on solid supports have emerged as a new frontier in catalysis science owing to their great potential to bridge the gap between heterogeneous and homogeneous catalysis. The active centers of this new class of materials possess unique electronic structure and unsaturated coordination environments, which have been proven to improve catalytic activity in a variety of reactions. Moreover, the homogeneity in the active sites and geometric structure of SACs, which show similarities to their homogeneous catalyst analogs, afford them a great potential to enhance selectivity because of similar spatial and electronic interactions to substrates.

To this end, this themed collection of Journal of Materials Chemistry A aims to provide a platform for recent developments in this rapidly evolving field of SACs including synthetic strategies, selectivity regulation, theoretical understanding of the catalytic activity and stability, single-atom alloy, support effect, and novel applications in electrocatalysis, photocatalysis, photoelectrocatalysis, selective hydrogenation, and other fields. We hope that readers find this themed collection informative and useful. Guest Edited by Zhiqun Lin (Georgia Institute of Technology, USA), Maria Escudero Escribano (University of Copenhagen, Denmark) and Jun Li (Tsinghua University, China).
