Graphene aerogel-based catalysts in Fenton-like reactions for water decontamination: a short review

Fenton-like reactions represent an effective strategy to generate strongly oxidative species for the elimination of refractory organic pollutants in water. In the past decades, many research efforts have been made to the development of heterogeneous catalysts in Fenton-like reaction, in order to add...
