Cobalt incorporation and MoS₂–NiS₂ heterostructure synergistic for improving full water electrolysis efficiency

Abstract

Designing a robust bifunctional water splitting catalyst at low-cost manifests great importance for water splitting. Herein, the in-situ generated MoS2/NiS2 nanosheet heterostructures by cobalt incorporation on carbon paper (Co-MoS2/NiS2/CP）have firstly...

A review of modulation strategies for improving the catalytic performance of transition metal sulfide self-supported electrodes for the hydrogen evolution reaction

“…In recent years, modulating the morphology of materials is one of the effective ways to improve the water splitting performance of electrocatalysts. In recent years, researchers have reported transition metal sulfide electrocatalysts with different morphology structures, for example, one-dimensional (1D) CoS 2 nanowires 59 and Co 9 S 8 nanowires, 60 two-dimensional (2D) Co-MoS 2 /NiS 2 nanosheets, 61 and three-dimensional (3D) coral-like NiS/FeS 2 . 62 Therefore, by modulating the morphology and structure of the electrocatalysts, the active specific surface area of the catalysts can be effectively increased to expose more active sites; at the same time, the diffusion resistance of the electrolyte can be reduced to enhance the diffusion of ions and the rapid transfer rate of electrons.…”

Integrating multiple regulatory strategies: phase, morphology and interface engineering to construct a hierarchical Ni2P–MoS2/rGO heterostructure catalyst for efficient oxygen reduction reaction

“…22,23 It has been both experimentally and theoretically identified that the reasonable fabrication of a heterointerface can effectively reduce the adsorption/desorption barrier of reaction intermediates via adjusting the electronic structure, the abundant defects and distorted structures as well as the strong synergistic effect between varying active sites. 24–26 For example, Sebastian et al synthesized NiFe 2 O 4 nanoparticles supported on 2H/1T multiphase MoS 2 nanosheets. 27 Due to the unique synergetic effect stemming from the strong interaction between NiFe 2 O 4 and MoS 2 , the NiFe 2 O 4 /MoS 2 heterostructured composite catalyst exhibits an outstanding ORR activity and remarkable stability.…”

An advanced PdNPs@MoS2 nanocomposite for efficient oxygen evolution reaction in alkaline media

“…This raises signicant concerns about the feasibility of initiating extensive research on renewable energy reservoir development and related technologies. [1][2][3] Hydrogen has high energy density and zero carbon emissions into the atmosphere, so it has shown high potential and is capable of meeting the challenges of the energy sector. Natural gas reservoirs have traditionally been converted to hydrogen via steam-reforming.…”
