Abstract
The electrocatalytic means of splitting of water is one of the advantageous processes for the purified hydrogen production with no carbon emission alongside. Searching of effective catalysts with lesser input of energy is unavoidable for the commercial-scale hydrogen supply. The state-of-the-art catalysts for oxygen evolution reaction (OER) are IrO2 and RuO2 and for hydrogen evolution reaction (HER) it is Pt that still remains a competing one. Recently, transition metal–based catalysts were found to be promising for both OER and HER particularly in alkaline conditions. Other than this, transition metal nitrides (TMNs) got attention for both OER and HER owing to their unique electronic structure and electrical conductivity nature. TMN-based composite materials possess improvised catalytic properties because of their modified electronic structure which leads to better synergistic effects that resulted in improvised electrocatalytic activity and also stability. This chapter highlights the TMNs in electrochemical water splitting in various aspects such as structure, electronic nature, and surface modifications for betterment of activity and stability for the production of hydrogen.
