Abstract

This study aims to analyze the effect of the type of electrode in the electrolysis of seawater for the production of hydrogen gas. The methods used include two types of electrodes, namely copper and aluminum and also design tools for electrolysis of seawater. Data collection is carried out every 20 minutes, the electrolysis process takes place at a constant voltage of 12 volts. The results obtained showed that the copper electrode produced 732 ml of hydrogen gas and a lifetime of 820 minutes with an average rate of 0.893 ml/minute and the highest hydrogen yield of 3.83% at 400 to 440 minutes while the aluminum electrode produced 693 ml of hydrogen gas. and a lifetime of 680 minutes with an average rate of 1.019 ml/minute and the highest hydrogen yield of 5.92% at 120 minutes.

Abstract

Electrodeposited nickel coating has excellent physical and mechanical properties, however it does not withstand to high temperature oxidation for long time. The addition of nitride phase within the nickel based coating improve the oxidation resistance through dense surface morphology improvement. A preliminary study was performed to investigate the high temperature oxidation behavior on the coating morphology after exposed at high temperature. The Ni-TiN/Si3N4 composite coatings deposited at electrodeposition temperature of 35 ℃, 40 ℃ and 50 ℃. The electrolyte consists of 0.17 M NiCl2.6H2O, 0.38 M Ni2SO4.6H2O, 6 g/L TiN, 0,6 g/L Si3N4, 40 g/L H3BO3, 0,6 g/L Sodium Dodecyl Sulfate (SDS).  High temperature oxidation process on the samples was performed by heating at temperature of 700 ℃ for 2 hours within air conditions. The morphology and composition samples were characterized by using SEM/EDS. In general, the result showed that the morphology of Ni-TiN/Si3N4 composite coatings became rough due to the oxidation process. Elements coating such as Ni, Ti, Si and N were disappeared after the oxidation process due to the outward diffusion process.
