Site preferences and ordering in Nb(Al1-xMx)2 (M = Ni or Cu) ternary Laves phases

A step-by-step strategy to design active and stable quaternary intermetallic compounds for the hydrogen evolution reaction

“…27 Second, TaCo 2 belongs to the Laves intermetallic phase that can accommodate various elements and one can incorporate different elements based on the desired function. 28,29 For instance, Cu is considered to be a ductile metal and the addition of a small amount of Cu can increase the ductility of intermetallic compounds (e.g., the case of NiAl). This may facilitate the bonding between particles during sintering, which can improve the electrocatalytic stability of TaCo 2 for long-term operation.…”
