Abstract
This chapter presents an overview of the determination of active sites on metal-free, carbon-based catalysts in multifunctional applications. Electrochemical reduction reaction, including oxygen reduction reaction (ORR) and hydrogen evolution reaction (HER), is an important half reaction in many fields of renewable energy conversion, production, and storage. The chapter discusses the catalytic effect of the two functional groups on carbon-based nanomaterials, namely the oxygen-containing species and the nitrogen-containing species, toward the oxygen evolution reaction (OER). Nitrogen-doped carbon nanomaterials can be prepared by pyrolysis of nitrogen-rich polymers, which have exhibited outstanding OER activities in alkaline media even exceeding those of the traditional noble metal electrocatalysts. Density functional theory (DFT) calculation offers a powerful tool to study electrocatalysis. Carbon dioxide (CO2) emission resulted from combustion of fossil fuels greatly threatens the human society and has become the most urgent concern at the global level. © 2018 Wiley-VCH Verlag GmbH & Co.
