Abstract

A Fe₇₈Si₉B₁₃ nanoglass with improved alkaline hydrogen evolution performances is prepared by melt spinning followed by high-pressure torsion (HPT). HPT treatment induces slight unique crystallization meanwhile generates abundant interfaces/regions both inside the amorphous matrix and between the amorphous matrix and nanocrystallites. In 1.0 M KOH, the nanoglass requires an overpotential of only 112 mV to achieve the current density of 10 mA cm^–2, which is much smaller than those of the corresponding amorphous alloy (385 mV) and crystalline alloy (465 mV). Furthermore, catalytic performance of the nanoglass remains almost unchanged after 50 h continuous reaction.
