Method for preparing Ru nanoflower electrocatalyst with hierarchical structure in one pot
The invention relates to a Ru nanoflower electrocatalyst with a hierarchical structure, and belongs to the field of preparation of novel nano catalytic materials. A material synthesis method used in the invention is a polyol method. The preparation method comprises the following specific steps: firstly, dissolving polyvinylpyrrolidone and ruthenium chloride into ethylene glycol, adding a formaldehyde solution and ultrapure water into the solution according to a certain proportion, transferring the solution into a high-pressure reaction kettle with a polytetrafluoroethylene lining, putting the high-pressure reaction kettle into a constant-temperature blast drying oven, and carrying out a heating reaction; and centrifuging, washing and drying the obtained product to obtain a black powdery solid, namely the Ru nanoflower electrocatalyst with the hierarchical structure. The preparation method is simple and easy to implement, the synthesized catalytic material is stable in performance, and experimental conditions are green, environment-friendly, mild and suitable for large-scale production..
