Overview

Research observes improved water splitting in engineered electrocatalysts, highlighting implications for hydrogen production.

Key Points

  • The aim is to enhance water electrolysis efficiency through engineered bifunctional electrocatalysts.
  • Constructed iron-cobalt hydroxides via interfacial engineering.
  • Optimized molar ratios of Fe and Co for active catalyst sites.
  • Conducted electrochemical tests to evaluate performance metrics.
  • Achieved overpotentials of 0.270 V for oxygen and 0.192 V for hydrogen evolution.
  • Demonstrated a turnover frequency of 0.165 s-1 and high mass activity of 11.2 A g-1.
  • Operated a symmetric electrolyzer at 1.61 V for 10 mA cm-2, comparable to existing benchmarks.
