The invention discloses a doped photocatalyst for treating landfill leachate and a preparation method and application thereof. The photocatalyst is represented by the general formula A-B-LaFeO 3 -Y, where A is Mn, Mo, Co or Cr, B is N, B, F or S , LaFeO is an active component, Y is a porous carrier, the mass ratio of A , B and LaFeO is 1‑4:2‑8:100, and the mass ratio of LaFeO and Y is 30 ‑40:100. The catalyst of the invention is modified by co-doping specific metal components and non-metal components, so as to effectively regulate the electronic structure of the catalyst, suppress the recombination of photo-generated electron-hole pairs, and improve the photocatalytic efficiency; The photocatalytic efficiency is improved, the problems of low treatment efficiency and long period of the current photocatalytic oxidation technology are solved, and the pollutant degradation efficiency is significantly improved. |
