NOVELTY - An electrolyzing low-temperature low-salinity seawater anode is prepared by taking soluble salt of a ruthenium element, soluble salt of a titanium element, and soluble salt of a palladium element; dissolving in water to total metal concentration of 110-140 g/L, where molar ratio of ruthenium element is 20-35 mol.%, molar ratio of titanium element is 40-60 mol.%, and molar ratio of palladium element is 5-25 mol.%; %-25 % to obtain salt solution; adding graphene powder and ultrasonic mixing with salt solution to obtain active coating liquid; pickling metal substrate containing titanium element and removing surface oxide layer; coating the active coating liquid; heating under oxygen-containing atmosphere at 400-450 degrees C for 30-100 minutes; continuously coating active coating, heating to 450-550 degrees C for 30-100 minutes, coating active coating, and heating to 450-550 degrees C for 30-100 minutes; and sintering to 450-550 degrees C for 200-300 minutes. USE - Electrolyzing low-temperature low-salinity seawater anode. ADVANTAGE - The electrolytic low-temperature low-salinity seawater anode has high electrolytic efficiency, long service life, high catalytic activity, which can effectively reduce the anode chlorine over potential and reduce the electric energy consumption for electrolytic low-temperature low-salinity seawater anode.
