In this study, a carbonized aerogel (CA) decorated with Mn-FeOOH hybrid nanoparticles was prepared and has been used as a better heterogeneous photo-Fenton catalyst. Mn doping accelerated the regeneration of Fe2+ and promoted the decomposition of H2O2 while producing many hydroxyl radicals (·OH), which solved the mass transfer problem in the traditional heterogeneous Fenton system. The amount of·OH in the Mn-FeOOH@CA/H2O2 system within 40 min was 2.4 times higher than that in the FeOOH@CA/H2O2 system, which further indicates that·OH was the ...
