Key Points

This research aims to investigate the impact of high-density phosphorus doping on improving the activity of metal-free carbon catalysts for electrosynthesis of hydrogen peroxide.
High-density phosphorus doping performed on carbon spheres
Evaluation of 2e⁻-oxygen reduction reaction (ORR) activity
Analysis of the catalytic performance under various conditions
High-density phosphorus doping significantly improved the 2e⁻-ORR activity
Increased hydrogen peroxide selectivity observed during electrosynthesis
Demonstrated notable enhancement in catalyst performance compared to undoped counterparts

Implication

Assesses high-density phosphorus doping to enhance hydrogen peroxide production in carbon catalysts, indicating improved electrosynthesis efficiency.

Abstract

While heteroatom doping is competent to enhance 2e⁻-ORR activity of metal-free carbon catalysts, high-density phosphorus doping remains underexplored due to large atomic radius of P atom and oxidation tendency. Herein,...
