The Effect Of NAOH Catalyst On Hydrogen Production Produced Through The Electrolysis Process Of Seawater From Mangrove Area

Abstract

This research was conducted to examine the volume of hydrogen, hydrogen production rate and hydrogen yield produced through the electrolysis process of seawater from mangrove area with 0.5 M ,1 M, and 1.5 M of NaOH as catalyst. The process was carried out using copper electrodes at a voltage difference of 12 V and an interval of 20 minutes for each measurement of hydrogen volume which was determined using the water displacement method. The lifetime of the copper electrode was also analyzed to determine the resistance of the electrodes to corrosion caused by chlorine. The results showed that an addition of NaOH catalyst can increased the hydrogen production by the electrolysis process of seawater around mangrove areas and the optimal catalyst is NaOH 1 M, which produced 671.8 ml of total hydrogen gas in 1700 minutes. The use of seawater from mangrove areas in producing hydrogen through the electrolysis process in addition with NaOH as catalyst, provided an opportunity to extend the electrode lifetime, prevent corrosion, and also to produce more hydrogen as a source of clean and environmentally friendly energy, as well as to promote conservation and rehabilitation of mangrove.
