A self-supporting metal or metal oxide catalyst having a core-shell structure is disclosed. The general formula of the catalyst is xM-yMO@zShell/mAlO/ZT, wherein the x is 0-5% by mass, the y is 0-10%by mass, the z is 0.5-20% by mass, the m is 0.1-20% by mass, and the catalyst includes the M, the Mo, the Shell and the AlO, with the balance being the ZT. The catalyst is prepared by a method including (1) a step of subjecting the ZT to hydrothermal treatment and/or thermal treatment in pure water or an aqueous solution containing an aluminum source and an alkali source to prepare a self-supporting AlO/ZT composite carrier, and (2) a step of soaking the prepared AlO/ZT carrier by utilizing an organic solution containing at least one metal M ion and coordinated with a coupling agent, and performing drying, calcination and reduction to prepare the catalyst. The catalyst can be used for catalytic oxidation of low-concentration methane and volatile organic compounds (VOCs), catalytic oxidation of carbon monoxide, lower olefin preparation from synthetic gas (FTO), and methane conversion to prepare synthetic gas.
