The method includes the following steps: first synthesizing a COF by a solid-phase method at room temperature; then mixing the COF with a transition metal salt, and conducting stirring and drying to obtain a precursor; and finally calcining the precursor under the protection of an inert gas by an in-situ pyrolysis method, to obtain a target product. According to the method in the present invention, a monatomic catalytic material with high catalytic active site dispersibility and high catalytic stability is successfully constructed. The method not only covers a wide range of metal types, has low costs, simple operation steps, and easily controllable reaction process conditions, but also does not require expensive equipment and special raw materials and a complex process, and can implement large-scale production.1/2 800. 20.T~ 600S4002000 p 10 20 30 40 s0 60 70 go 90 2 Theta (deg.)
