dc.description.abstract A series of perovskite-like oxides LaCu1-xMxO3 (M=Mn, Ti; 0.0 ⩽ x ⩽ 0.8) was prepared by amorphous citrate decomposition and characterized by XRD, ICP-OES and XPS techniques. The catalysts were tested in the Fenton-like degradation of paracetamol with H2O2, under mild reaction conditions, 25 °C and nearly neutral pH. Values of decomposition of paracetamol between 80 and 97% at 300 min were achieved for most of samples. The presence of the Cu2+/Cu+ pair at the surface of the catalysts is necessary to carry out the reaction and the catalysts containing higher amount of copper at the surface, resulted to be more active. The leaching of metals was less than 1%, which discards the contribution of the homogenous Fenton-like reaction and remarks the high stability of the metals into the mixed oxide network. The catalytic activity of LaCu0.8Mn0.2O3 was maintained after three cycles of reaction, which proves the stability and reusability of the catalyst. spa
