Phenol hydroxylation catalyzed by the rare earth-adulterated copper-containing hydrotalcites
Owing to the fact that the presence of the Cu+ species in La-Cu-HTLcs/H2O2 system is detected by the X-ray photoelectron spectra (XPS), the generation of HO. radicals is deduced to be carried out by the reaction of HO-Cu+-OH species with H2O2.
