Abstract
The use of single-atom catalysts (SACs) for acidic oxygen evolution reaction (OER) is an emerging field of research with prospects to maximize the dispersion of active sites and the metal utilization. Therefore, it is promising for reducing the amount of noble metal needed to efficiently electrocatalyze the OER. The objective is to achieve comparable activity for conventionally unsupported and supported iridium and ruthenium oxide catalysts but with significantly lower loading of precious metal. The present review summarizes the recent progress in this field, discussing the preparation of such materials, the structural characterization techniques suited to probe single metal atoms as well as the hitherto achieved activity and stability in acidic OER conditions. We conclude the short review with a summary of the main observations and perspectives for this class of materials.
期刊介绍：
The development of the Current Opinion journals stemmed from the acknowledgment of the growing challenge for specialists to stay abreast of the expanding volume of information within their field. In Current Opinion in Electrochemistry, they help the reader by providing in a systematic manner:
1.The views of experts on current advances in electrochemistry in a clear and readable form.
2.Evaluations of the most interesting papers, annotated by experts, from the great wealth of original publications.
In the realm of electrochemistry, the subject is divided into 12 themed sections, with each section undergoing an annual review cycle:
• Bioelectrochemistry • Electrocatalysis • Electrochemical Materials and Engineering • Energy Storage: Batteries and Supercapacitors • Energy Transformation • Environmental Electrochemistry • Fundamental & Theoretical Electrochemistry • Innovative Methods in Electrochemistry • Organic & Molecular Electrochemistry • Physical & Nano-Electrochemistry • Sensors & Bio-sensors •
