Cyclic voltammetry electrodynamic deposition of Co 9- x Mn x S 8 nanosheet arrays for electrocatalytic hydrogen evolution

Room-temperature cyclic voltammetry (CV) electrodynamic deposition is proposed herein for the first time to deposit Co Mn S nanosheet arrays. The incorporation of Mn spin states induces atomic distortion, which contributes to more active edge sites and the fine-tuning of the electronic structure. Th...

Description
Summary:Room-temperature cyclic voltammetry (CV) electrodynamic deposition is proposed herein for the first time to deposit Co Mn S nanosheet arrays. The incorporation of Mn spin states induces atomic distortion, which contributes to more active edge sites and the fine-tuning of the electronic structure. The Co Mn S ( = 4.5) catalyst exhibits enhanced catalytic activity toward the hydrogen evolution reaction (HER) when compared with pristine Co S . This work offers a promising strategy for the design of highly efficient HER electrocatalysts.
