When Cubic Cobalt Sulfide Meets Layered Molybdenum Disulfide: A Core–Shell System Toward Synergetic Electrocatalytic Water Splitting

Abstract

A new class of Co9 S8 @MoS2 core-shell structures formed on carbon nanofibers composed of cubic Co9 S8 as cores and layered MoS2 as shells is described. The core-shell design of these nanostructures allows the advantages of MoS2 and Co9 S8 to be combined, serving as a bifunctional electrocatalyst for H2 and O2 evolution.

In situ hybridization of an MXene/TiO2/NiFeCo-layered double hydroxide composite for electrochemical and photoelectrochemical oxygen evolution

“…Recently, transition-metal-based compounds, such as suldes, 7,8 (oxy)hydroxides, 9,10 oxides 11-13 and layered double hydroxides (LDHs) [14][15][16][17] 18-20 For example, introducing Fe to NiCo-LDH could boost its OER performance, most likely due to the enhanced conductivity and increased level of structural disorder.…”

Hierarchical NiCo2O4 Hollow Microcuboids as Bifunctional Electrocatalysts for Overall Water‐Splitting

“…However, NiCo 2 O 4 that can be used as an electrocatalyst in HER has not been studied yet. [5] It is highly desired to design effective catalysts for water splitting by using non-noble metals.Inthis regard, transition-metal oxides,chalcogenides, and phosphides have been demonstrated as promising electrocatalysts for the OER and HER reactions in water splitting. Water splitting has been widely regarded as ap romising and sustainable approach of producing clean hydrogen fuel from aqueous solutions.…”

Self-standing Ni-WN heterostructure nanowires array: A highly efficient catalytic cathode for hydrogen evolution reaction in alkaline solution

“…As a result, decreased HER activity is observed. We thus propose that the superior HER activity of Ni-WN heterostructure nanowires array in our present study can be attributed to the electrocatalytic synergistic effects of Ni and WN [14,15,35,36].…”
