Recent progress on transition metal-decorated and heteroatom-doped porous carbon-based oxygen catalysts
Abstract
<p indent="0mm">Efficient and clean energy storage and conversion devices are essential for future social development. However, the slow oxygen reduction reaction (ORR) and oxygen evolution reaction (OER) considerably limit the energy efficiency and operating life of metal-air batteries, fuel cells and water splitting devices. Preparing inexpensive, efficient, stable, and environment friendly catalysts for ORR and OER is crucial for promoting the commercial application of these energy conversion devices. Herein, the recent advances in transition metal-decorated and heteroatom-doped porous carbon-based catalysts for ORR and OER and their structure-activity relation are analyzed. Finally, theoretical calculations are discussed to summarize the effects of transition metal decoration and heteroatom doping on the electrochemical properties of carbon-based materials, and the challenges and opportunities in this field are proposed.</p>
