TiO2/P/C electrode material and preparation method and application thereof

The invention belongs to the technical field of electrode materials and rare earth recovery, and discloses a TiO2/P/C electrode material and a preparation method and application thereof. The preparation method comprises the following steps: dispersing sodium titanate into a phytic acid solution, stirring for reaction, centrifuging and washing a solid product, dispersing the solid product into a tris (hydroxymethyl) aminomethane solution, and ultrasonically mixing uniformly to obtain a mixed solution; then dispersing dopamine hydrochloride into the mixed solution for stirring reaction, and washing and drying a product to obtain a precursor; and carrying out carbonization treatment on the obtained precursor in an inert atmosphere at the temperature of 600-900 DEG C to obtain the TiO2/P/C electrode material. The selective recovery efficiency of the obtained electrode material on rare earth ions such as Eu, Dy, Tb and Lu can reach 99% or above, and the electrode material has wide application prospects in the fiel
