Preparation method of novel carbon nano tube loaded ruthenium-based superfine nano heterogeneous electrocatalyst

The embodiment of the invention discloses a preparation method of a novel carbon nano tube loaded ruthenium-based superfine nano heterogeneous electrocatalyst, which comprises the following steps: dissolving a metal ruthenium salt, a functionalized multi-walled carbon nano tube and 1, 3, 5-benzene tricarboxylic acid in a mixed solvent of glacial acetic acid and ultrapure water, and uniformly mixing; transferring the mixed solution into a high-pressure hydrothermal reaction kettle, putting the high-pressure hydrothermal reaction kettle into a drying oven, and carrying out heat preservation for hydrothermal reaction; centrifuging and drying the reacted mixed solution to obtain a blackish green precursor material, and sequentially placing the blackish green precursor material in a tubular furnace and a muffle furnace for heat treatment to obtain the novel carbon nanotube loaded ruthenium-based superfine nano heterogeneous electrocatalyst. The hierarchical porous ruthenium-based carbon material catalyst has a hig
