Preparation method and application of Ru-ZnFexOy heterogeneous nanosheet modified porous carbon material

The invention provides a preparation method of a Ru-ZnFexOy heterogeneous nanosheet modified porous carbon material, which is characterized in that mushroom waste residues and low-toxicity metal salts (ferric salt, zinc salt and ruthenium salt) are used as raw materials, and a novel Ru-ZnFexOy heterogeneous nanosheet modified porous carbon material is constructed by optimizing and regulating the preparation method and strategy. According to the material, a simple and green preparation method of the biomass-based carbon material loaded Ru nano-catalyst capable of being prepared in an amplified manner is developed by utilizing heteroatom sources (amino acid, protein and the like) rich in biomass mushroom residues under the condition that no external template is added. A further research discovers that the Ru-ZnFexOy heterogeneous nanosheet modified porous carbon material as an electrocatalyst shows excellent catalytic activity in hydrogen production from alkaline pure water and seawater, and the catalytic activ
