Title : Ultrathin iron cobalt oxides nanosheets as highly active electrocatalyst for water splitting

Abstract:

Electrochemical water splitting is an effective method for storing electrical energy in the form of H2 fuel, but hurdled by the sluggish anodic oxygen evolution reaction (OER). It is thus important to develop an efficient OER catalyst with large surface area, abundant active sites, and good stability through simple and economical method. Herein, we introduce a facile solution reduction method to prepare the iron-cobalt oxide nanosheets with a large specific surface area, ultrathin thickness (1.2 nm) and, importantly, abundant oxygen vacancies. The activity of the new catalyst was superior to those of commercial RuO2 and most of reported OER catalysts. The mechanisms for the excellent OER catalytic activity of the new catalyst will also be discussed (Advanced Materials 2017, 29 (17), 1606793).
