The application discloses a kind of multiphase high-entropy
alloy and preparation method and application thereof, belong to the technical field of catalyst efficient activation PMS removes organic pollutants;The
metal atom composition of the multiphase high-entropy
alloy includes five or more in Co, Cu, Mn, Al, La or Cr;The
atomic ratio in the multiphase high-entropy
alloy is equimolar, and according to the above-mentioned
metal atom composition and the
hydrate nitrate of ratio relationship is added into
solvent, and precursor solution is prepared;The precursor solution is sequentially pyrolyzed, dried, ground and calcined, and finally the multiphase high-entropy alloy is prepared.The application provides a kind of can reach excellent activation effect and catalyst stability under the condition of no
external energy input, and still provides the removal thought of always existing small amount of overflow
metal ions and part of not completely mineralized material existing in
advanced oxidation process under normal
temperature and pressure condition, solves the effect evaluation problem of high-entropy alloy CoCuMnAlLaCr in activation PMS and degradation removal organic pollutants.
