3D nanoporous NiCoP as a highly efficient electrocatalyst for the hydrogen evolution reaction in alkaline electrolyte

Abstract

Transition metal phosphides (TMPs) have demonstrated deep potential for accelerating electrocatalytic hydrogen evolution reaction (HER). Herein, we present the facile synthesis of nickel cobalt phosphide electrocatalyst with 3D nanoporous on...

Optimization of Functional Blocks of Organic Ligands Regulating the Electrocatalytic Hydrogen Evolution Reaction of Co(II)- or Ni(II)-Based Organic Frameworks/Nickel Foam Composites

“…After 12 h of continuous testing, the current density remained unchanged, and the results showed that the material also had good stability. The results of the synthesized electrocatalysts are compared with those of nickel phosphide reported in the literature, which show that the synthesized electrocatalyst has a better performance than nickel phosphide. − We also provide a table comparing the HER activity of these catalysts to previously reported compounds, − as shown in Table S5.…”

Hollow Co nanoparticle/carbon nanotube composite foam for efficient electrocatalytic hydrogen evolution

“…ECSA on the other hand typically suggests more possible sites for catalysis. 53,54 Fig. 6e depicts C dl (in proportion to the ECSA) of a Co/NCNT-25 electrode as a function of scan rates (Fig.…”

“…6d and Table S3 ECSA on the other hand typically suggests more possible sites for catalysis. 53,54 Besides high activity, another important criterion for highperformance electrocatalysts was to verify their long-term stability. [55][56][57] The Co/NCNT-25 catalyst was used to test the stability in 1 M KOH (Fig.…”

CoFe2O4/g-C3N4 intercalated Ti3C2 MXene for efficient electrocatalytic hydrogen evolution reaction

“…2 Hydrogen production via electrocatalysis has gained more traction due to the properties associated with the electrocatalyst compared to those of other catalysts. 3–5 Overall water splitting (OWS) produces hydrogen via the hydrogen evolution reaction (HER) and oxygen via the oxygen evolution reaction (OER) at the cathode and anode, respectively as given in eqn (1) and (2).Cathodic reaction: 2H + + 2e − ↔ H 2 Anodic reaction: 2H 2 O ↔ O 2 + 4H + + 4e − …”
