The invention provides a copper sulfide/silicon dioxide/manganese dioxide nano composite particle, a preparation method and application. The preparation method comprises the following steps of synthesizing copper sulfide by a one-pot method, preparing CuS@SiO2 nano particles by a sol-gel method, dissolving the CuS@SiO2 in an ethanol solution, adding an ammonium nitrate solution, performing reacting to obtain CuS@mSiO2 nano particles, and finally, mixing the CuS@mSiO2 nano particles with a KMnO4 solution, and performing reacting to obtain a CuS@mSiO2@MnO2 nano composite. The specific surface area of the prepared copper sulfide/silicon dioxide/manganese dioxide nano composite particle is 360.82-364.82 m *g<-1>, and the average pore size is 3.0-3.2 nm. The method provided by the invention is mild in reaction conditions, and the prepared copper sulfide/silicon dioxide/manganese dioxide nano composite particle can be used for photothermal therapy and nuclear magnetic imaging, and is highin photothermal conversion
