Interface-engineered 1T/2H-MoS2 on 3D nickel foam enables accelerated hydrogen evolution kinetics

We report a single-step pulsed electrodeposition strategy that grows mixed-phase 1T/2H-MoS 2 conformally on a porous nickel foam (NF) scaffold, yielding a self-supported MoS 2 /NF electrode. In 1.0 M KOH, MoS 2 /NF requires only an overpotential of −52 mV to deliver −10 mA cm −2...
