The invention discloses a method for synthesising a tetraphenylporphyrin metal complex via a one-step process, comprising the following steps of: (1) dissolving metal acetate in DMF (dimethyl formamide), wherein the ratio of the metal acetate to DMF is 1 g: (8 to 16 ml); (2) adding a solvent, namely, propionic acid, in a reaction container, then sequentially adding benzaldehyde, the DMF solution dissolved with the metal acetate, and a pyrrole solution diluted by propionic acid, and refluxing for 30-120 minutes at a temperature ranging from 120 to 150 DEG C, wherein the molar ratio of benzaldehyde to pyrrole to the metal acetate is 1: 1: (0.25 to 2.5), and the volume ratio of the solvent, namely, propionic acid, to DMF is 1: 1 to 1: 1.5; and (3) after the reaction is concluded, cooling, removing the solvent, and separating to obtain the product. The process has the characteristics of being low in the cost of the used raw materials, moderate in reaction conditions, simple to operate, less in pollution and envir
