“…Transition metal carbides have received great attention as electrocatalysts for water splitting due to their high electrical conductivity, unique electronic structure, chemical stability, and low cost. ,,− Actually, the studies related to the carbide HER and OER electrocatalysts (i.e., TiC, ZrC, HfC, NbC, Cr 3 C 2 , Mo 2 C, WC, etc.) had already started in the late 1960s. , Among the carbide materials reported up to now, Ni-, Co-, and Fe-based carbides are good candidates for OER electrocatalysts due to the superb activity of Ni, Co, and Fe metals for alkaline OER electrocatalysis. ,,,,,,,,, Additionally, W- and Mo-based carbides, which are good electrocatalysts for the HER, have also been reported as bifunctional electrocatalysts for overall water splitting in the OER field. ,,, …”
