  Pulverized coal has good specific surface area, surface activity and adsorption properties, which can be used to construct new carbon materials. In this work, a coal-based multi-rare earth composite catalyst was synthesized by a simple dissolution carbonization method, and its catalytic performance for the activation of persulfate was investigated with TC as the target pollutant. The results showed that the porous carbon-based catalyst with uniform doping of transition metals and rare earth metals was prepared with pulverized coal as carbon source, with a specific surface area of 654 m²/g, 95.7% of tetracycline hydrochloride (20 ppm) dissolved in water could be removed by 0.1 g/L PC-FeCoNiSmNd activation of 1mM PMS for 30 min, and the activation energy of the reaction system was calculated to be 16.21 kJ/mol, and according to the free radical quenching reaction, •OH , SO₄^•− , O₂^•− and ¹O₂ were calculated.
