3D red blood cell-like Co-BTC material and preparation method and application thereof

The invention provides a 3D red blood cell-like Co-BTC material and a preparation method and application thereof, and belongs to the technical field of electrocatalytic materials.The 3D red blood cell-like Co-BTC material is prepared with Co (NO3) 2.6 H2O and H3BTC as raw materials through a sonochemical method, in-situ growth and an electrostatic self-assembly method, the 3D red blood cell-like Co-BTC material is of a 3D hollow sphere structure composed of 1D hollow nanorods, and the 3D hollow sphere structure is of a hollow sphere structure. According to the material, due to the special red blood cell-like sphere structure composed of the hollow rods, the electron transfer speed and the mass transfer speed are increased, and therefore the HER performance is improved. The method is simple in process, convenient to operate and short in reaction time, so that the energy consumption is reduced, the production cost is saved, batch production is facilitated, and the non-toxic, harmless and environment-friendly re
