Abstract: The invention belongs to the technical field of preparation of a ceramsite catalyst and discloses a ceramsite catalyst containing metal oxide particles and a preparation method and application thereof. The preparation method including the following specific steps of: dissolving a metal salt with an ozone catalytic activity in water to obtain a metal salt solution; mixing the metal salt solution with a ceramsite raw material to prepare a ceramsite embryoid body; and sintering the ceramsite embryoid body at a high temperature to obtain the ceramsite catalyst containing metal oxide particles. The ceramsite catalyst containing metal oxide particles of the invention can be repeatedly used, so that secondary pollution is reduced; and with the same ozone input quantity, by adding the ceramsite catalyst containing metal oxide particles of the present invention, the efficiency of water treatment through ozone oxidization can be increased by 41.35%.
