AlB

is a lamellar transition metal boride that is prepared by selectively etching the MoAlB MAB phase precursor. Most methods for synthesizing Mo

AlB

require the use of strong acids or bases and a long reaction time. In this study

we present a Lewis acid molten salt method for synthesizing the lamellar structured Mo

AlB

by selectively etching a layer of aluminium atoms from the MoAlB precursor. The synthesized Mo

AlB

shows excellent catalytic activity for hydrogen evolution reaction under alkaline conditions

with long-term stability

and a low overpotential of 145 mV and Tafel slope of 76 mV dec
