A nano-network BiSbO4 and a method of synthesizing the same are provided. The method includes the following steps of: adding a surfactant into a solvent to form a solution, wherein the solvent includes water; adding a bismuth compound and an antimony compound into the solution to form a mixture; and heating the mixture with a hydrothermal method to obtain the nano-network BiSbO4. The nano-network BiSbO4 with an architecture of perpendicularly crossed single crystal nanorods of majorly exposed (001) planes is synthesized via surfactant-mediated growth in the present disclosure. The nano-network BiSbO4 with the architecture can effectively overcome the disadvantage of low electrical conductivity of metal oxides. |
