Metal-Free Catalyst for Persulfate-Based Advanced Oxidation Process

The replacement of metals in catalytic processes are highly demanded to improve sustainabilityand economic growth. The poor stability and metal leaching are the main drawbacks in metal-based catalyticreactions. This work represented the use of nitrogen and sulfur-dual doped mesoporous carbon material ((N,S)-MPC) as metal free catalyst for persulfate-based advanced oxidation process (AOP). Very low amount of(N, S)-MPC catalyst (wt%) exhibited superior performance for degradation of ۴-nitrophenol at roomtemperature and unadjusted pH.
