A Long-Term Test Using Tap Water (IMAGE) National Research Council of Science & Technology Caption The catalyst developed by KIST's research team uses 20% less iridium, a precious metal, than existing catalysts and shows at least 31% higher performance. A long-term test using tap water was performed to verify the practical feasibility of the catalyst. When tested, the catalyst maintained a high level of performance for hundreds of hours, indicating high durability. When the developed catalyst was applied to the actual carbon dioxide conversion system, the energy required during the process was reduced by more than half. This resulted in more than twice the amount of compounds typically produced at the same voltage using other iridium oxide catalysts.
