Rational design of open hollow nanoboxes via Ru and B synergistic electronic modulation in cobalt phosphide for efficient oxygen evolution reaction

Key Points

• The aim is to develop efficient and stable electrocatalysts for the oxygen evolution reaction using ruthenium-doped cobalt phosphide.
• Synthesis of open hollow nanoboxes incorporating ruthenium-doped cobalt phosphide and boron-nitrogen-codoped carbon.
• Characterization of electrocatalytic performance in alkaline water electrolysis conditions.
• Analysis of electronic modulation effects on catalyst efficiency.
• Enhanced oxygen evolution reaction performance observed in the Ru-CoP/BNC-1 nanoboxes.
• Stability of the electrocatalyst improved compared to traditional catalysts.
• Synergistic effects of ruthenium and boron-nitrogen codoping lead to higher catalytic activity.
