Pd nano tree-shaped structure as well as preparation method and application thereof

The invention discloses a Pd nano tree-shaped structure and a preparation method and application thereof. The preparation method comprises the following steps: cutting a glass slide into square blocks, and cleaning; the method comprises the following steps: weighing chloride-1-butylpyridine, dissolving the chloride-1-butylpyridine in a chloroform solution, adding 1-naphthol, and preparing a chloroform mixed solution as an oil phase in a reaction system after the 1-naphthol is dissolved; preparing a precursor solution as a water phase in a reaction system; putting a glass slide into a small cylindrical bottle for later use; adding the chloroform mixed solution into a small bottle, adding the precursor solution to form an oil-water two-phase reaction system, and standing for reaction; extracting an organic phase, transferring a product to a glass slide, then extracting an aqueous solution, loading the prepared product to the glass slide, cleaning and airing to prepare the Pd nano tree structure loaded on the gl
