Key Points

  • This research aims to develop and evaluate sodium-pectate nickel carbonized complexes as effective electrocatalysts for the hydrogen evolution reaction.
  • Catalysts based on sodium-pectate nickel complexes were synthesized and carbonized at 280°C.
  • The performance of the leading catalyst, with 25% sodium ion substitution for nickel, was tested at a voltage of 2.5 V and a temperature of 80°C.
  • The leading catalyst demonstrated a cathodic current density of 49% compared to the commercial Pt20%/C cathode catalyst at the same conditions.

Abstract

Hydrogen evolution catalysts based on sodium-pectate nickel carbonized complexes are developed. These catalysts are promising for use in water electrolyzers. The leading catalyst with the sodium ions’ 25%-substitution for nickel cations, carbonized to 280°C, is identified. The cathodic current density with this catalyst at a cell voltage of 2.5 V and temperature of 80°C equals 49% of that obtained with the commercial Pt20%/C cathode catalyst.
