Metallic glasses (MGs) are similar to silica in terms of their amorphous atomistic structure, chemical stability, and corrosion resistance , but have additional functionalities. Transition (Co/Ni/Fe) metal borides (TMBs) form MGs at 15-30 at% boron and are a viable alternative to silica shell coatings for nanoparticles. TMBs have been extensively explored as an economical alternative to noble metals for electrochemical water splitting , as catalyst supports, and for hydrogen generation from borohydrides .
