Abstract

A SO_x-decorated porous carbon electrocatalyst that exhibits excellent 2e⁻ oxygen reduction reaction activity is synthesized using UV-curing technology in combination with a pyrolysis process. The H₂O₂ selectivity using the SO_x-porous C shows 95.1% at 0.4 V and delivers a H₂O₂ production rate of 604.2 mmol g_cat⁻¹ h⁻¹. Density-functional theory calculations reveal the reasons for the improvement of catalytic performance.
