Abstract
In this research to reduce energy consumption of the electrolytic hydrogen production process, on the other hand still increase the efficiency, durability, and safety, we propose a catalyst from CO2 that decrease the use of energy and still produce the same amount of hydrogen. Wherein hydrogen and oxygen is produced from splitting carbonic acid (H2CO3) which comes from mixing CO2 and water (H2O). Based on the research conducted, hydrogen production rate when using CO2 as catalyst in lower voltage variation compensated the higher voltage. The best result regarding CO2 as catalyst after 300 minutes of electrolysis process, the lower voltage generate higher hydrogen volume.
