ABSTRACT
Electrocatalysts play a key role in improving the energy conversion efficiency and production rate of chemical reactions. This chapter introduces the applications of laser-induced graphene (LIG) in various chemical reactions. The first is based on LIG, and the second is based on LIG composites. Metal-free carbon nanomaterials have been widely studied as electrocatalysts for reactions such as oxygen reduction reaction and oxygen evolution reaction. In 2018, Zhang et al. used oxidized laser-induced graphene for oxygen electrocatalysis. The plasma treatment induced surface defects and increased the oxygenated functionalities. Electrochemical water splitting for the production of hydrogen is a promising method for the storage of intermittent renewable energy such as wind and solar energies. The advantages of using hydrogen as an energy carrier include a high energy density (~120 kJ/g) and a carbon-free emission.
