SOx-modified porous carbon as a highly active electrocatalyst for efficient H2O2 generation†
Abstract
A SOx-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 SOx-porous C shows 95.1% at 0.4 V and delivers a H2O2 production rate of 604.2 mmol gcat−1 h−1. Density-functional theory calculations reveal the reasons for the improvement of catalytic performance.
