In situ electrochemical metal (Co, Ni) oxide deposition on MoS₂ nanosheets for highly efficient electrocatalytic water splitting

Abstract

Highly active, robust and easy-to-get electrocatalysts based on earth-abundant elements are desirable to generate hydrogen and oxygen as fuels from water sustainably to replace noble metal materials. Here we report...

An amorphous FeCoNiMnCr high-entropy alloy supported by 2H-MoS2 on carbon cloth as a highly efficient and robust electrocatalyst for water oxidation

“…Meanwhile, the unique flower-like microstructure of 2H-MoS 2 has a larger specific surface area, which can ensure more active sites exposed for the FeCoNiMnCr@MoS 2 -CC electrocatalyst. 30 Thanks to the synergistic effects of FeCoNiMnCr and 2H-MoS 2 , the FeCoNiMnCr@MoS 2 -CC electrocatalysts show significantly enhanced electrocatalytic performance for the OER, with an overpotential of only 210 mV at a current density of 10 mA cm À2 , a small Tafel slope of 40.3 mV dec À1 in 1 M KOH solution, and good long-term stability at a current density of 10 mA cm À2 for 50 h.…”
