Porphyrin-based molecular catalysts possess a typical aromatic macrocyclic structure regarding their metal centers and coordination frameworks, allowing for the development of promising electrocatalysts through precise selection porphyrin ligand. However, reports on metalloporphyrins as electrocatalytic urea oxidation reaction (UOR) remain scarce. With these considerations in mind, triphenylamine-Ni(II) (NiPor-TPA) was synthesized solvothermal approach from 5,10,15,20-tetrakis [4-(diphenylamino)phenyl]porphyrin nickel(II) acetate this work. Experimental results reveal that introduction Ni species can serve active sites activate efficiently, thus prepared deliver better activity than metal-free TPA. The NiPor-TPA electrode delivers lowest potential 1.34 V versus reversible hydrogen (RHE) at 10 mA cm
