The invention discloses a preparation method, a product and application of a spherical tin-titanium oxide with a core-shell structure, and belongs to the technical field of gas-sensitive materials. The preparation method comprises the following steps: dissolving a tin source and a titanium source in a solvent, heating, and reacting to obtain the spherical tin-titanium oxide with the core-shell structure, a series of tin-titanium oxides with spherical core-shell structures and high specific surfaces are obtained by adopting a simple solvothermal synthesis method and changing the ratio of a tin source to a titanium source, and the tin-titanium oxides have good gas-sensitive response performance to triethylamine, ethanol, acetone and formaldehyde, are novel efficient gas-sensitive sensing materials, and have wide application prospects. The material can be used as a good material source of the gas-sensitive sensor, and has good application prospects and economic benefits in the field of gas-sensitive sensing; the
