Novel method for synthesizing porous flower-like nano palladium at room temperature

The invention provides a novel method for synthesizing porous flower-like nano palladium at room temperature, belongs to the technical field of nano materials, and solves the problem that the existing nano palladium preparation method is too complex. The novel method includes the steps of a, preparing a solution system composed of PdCl2, acid solution and HEPES (2-hydroxyethyl) in a reaction container; b, adding alkaline solution into the solution system obtained in the step a before mixing and neutralizing; c, allowing for standing at room temperature for a certain period of time to obtain product; d, subjecting the product to centrifugal collection, cleaning and drying to obtain the porous flower-like nano palladium. According to the novel method, anisotropic growth porous flower-like nano Pd crystals are prepared in the HEPES buffer solution. The novel method is simple and has low requirements on equipment. The prepared porous flower-like nano Pd has good catalytic performance on methanol, and is widely ap
