Electrocatalysis is one type of catalysis. The catalysts at the electrode/electrolyte interfaces can facilitate electrochemical reactions with high rates and stability via selective pathways at potentials close to their thermodynamic limits (i.e., minimum overpotentials). The first elaborated study for electrocatalysis can be dated back to the 1920s when Bowden and Rideal examined the electrolytic behaviors of a series of metal films for hydrogen evolution. However, it is not until 1963 that Grubb used the word “electrocatalysis” for the first time to name the electrochemical processes in fuel cells. Over the last decades, capturing and utilizing transient renewable energies such as solar and wind energy to offset the fast depletion of fossil fuels is becoming one of the mainstreams towards a clean and sustainable energy supply. Among these new energy technologies, energy conversion and storage are the critical steps in which electrocatalysis plays an indispensable role. In contrast to the traditional fossil fuel industry highly relying on high temperature/ pressure reactions, electrocatalysis usually operates at ambient temperature and pressure, significantly reducing largescale investment on the inflexible heat/pressure management equipment. Based on the above considerations and the witness of the growing commercialization of rechargeable battery/fuel cell-powered products, it can be predicted that electrocatalysis-related technologies will dominate the further development in many chemical/energy industries. *Corresponding authors (email: [email protected]; [email protected]; [email protected])
So far, the most widely studied electrocatalysis reactions include oxygen evolution reaction (OER), hydrogen evolution reaction (HER), oxygen reduction reaction (ORR), hydrogen oxidation reaction (HOR), CO2 reduction reaction (CRR), nitrogen reduction reaction (NRR), and methanol oxidation reaction (MOR). These electrocatalysis reactions lay the basis for chemicals/fuels production and utilization, e.g., hydrogen production by water splitting, electricity ge
