The invention discloses a method for rapidly preparing amide type octahedral metal-organic frameworks (MOFs) at the room temperature by using copper formate as a raw material. The method comprises thefollowing steps: dissolving copper formate tetrahydrate into a dimethyl formamide (DMF) solvent to prepare a salt solution, wherein the concentration of the copper formate tetrahydrate in the salt solution is 0.003-0.015mol/L; dissolving N, N', N''-tris-(3, 5-dicarboxyphenyl)-1, 3, 5-tri-carbamyl benzene into the DMF solvent to obtain a ligand solution, wherein the concentration of the N, N', N''-tris-(3, 5-dicarboxyphenyl)-1, 3, 5-tri-carbamyl benzene in the ligand solution is 0.0017-0.005mol/L; adding the ligand solution into the salt solution, wherein the volume of the added ligand solution is equal to that of the salt solution, and standing for carrying out a reaction until blue precipitate is generated in the solution so as to obtain a solution containing the amide type octahedral MOFs material; centrifuging
