Abstract The electrocatalytic performance of a Fe78Si9B13 amorphous alloy toward alkaline hydrogen evolution reaction (HER) is enhanced by ultrasonic vibration (UV). The UV treatments slightly increase the crystallization enthalpy of the Fe78Si9B13 amorphous alloy from 141.54 J/g to 145.32 J/g, meanwhile a large number of micro-cracks, -holes and -chips are generated on the surface of the amorphous alloy. The overpotentials of the amorphous alloy treated with ultrasonic energy of 5000 J is only… Expand
