SO x -modified porous carbon as a highly active electrocatalyst for efficient H 2 O 2 generation.

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 H 2 O 2 selectivity using the SO x -porous C shows 95.1% at 0.4 V and delivers a H 2 O 2 production rate of 604.2 mmol g cat -1 h -1 . Density-functional theory calculations reveal the reasons for the improvement of catalytic performance.
