A comparative study of self-doped TiO 2 catalysts obtained from different routes: analysis of efficiencies in the degradation of 2-chlorophenol under LED visible light

TiO 2 obtained via an eco-friendly sol–gel route exhibited higher photocatalytic performance than the MOF-derived oxide. The high degradation of 2-chlorophenol under LED visible light demonstrates the development of a sustainable treatment system.
