Abstract: A method for manufacturing a metal oxide-metal heterojunction nanoparticle is provided to vary the shapes of metal oxide-metal heterojunction nanoparticles such as a dumbbell shape and a flower shape. A method for manufacturing a metal oxide-metal heterojunction nanoparticle comprises the following steps of: mixing a metal precursor solution and an organic acid metal salt composite solution, wherein the metal precursor solution consists of a metal precursor, a surfactant and an organic solvent and the organic acid metal salt composite solution consists of an organic acid metal salt composite, the surfactant and the organic solvent; and pyrolyzing the mixture. The metal precursor is selected from the group consisting of HAuCl4.nH2O, H2PtCl6.nH2O, NiCl2 and AgNO3. The surfactant is selected among C1-C18 alkyl amines.
