The invention belongs to the field of nanomaterials and biomedical materials, in particular to a hollow - structured selenium-copper composite spherical nanoparticle and a preparation method and application thereof. , sodium borohydride is added to water, stirred, cuprous oxide is added, and the reaction is continued to stir, and the reaction product is centrifuged and dried to obtain cuprous selenide. The synthesis method of the invention is simple, and the hydrophilic copper-selenium hollow nano-composite can be synthesized by adding a reducing substance in the synthesis process. The Cu 2 Se prepared by the invention has good photothermal properties and chemical kinetic properties. The 2Se nanosystem can have good chemical kinetics at low hydrogen peroxide concentration and near-neutral pH (pH=6.5). |
