摘要 |
The present invention relates to a manufacturing method of iridium alloy nanocatalyst which coats iridium alloy sol, irridium sol, ruthenium sol including iridium, zinc, ruthenium, nickel, tin, and titanium on a substrate. According to the present invention, hydroxy radicals and oxygen radicals having strong oxidizing power are generated when electric energy is applied to the iridium alloy catalyst. Thus, the iridium alloy catalyst has an effect of removing biochemical oxygen demands such as carbon-based oxygen demand (CBOD), nitrogen-based oxygen demand (NBOD), chemical oxygen demand (COD), ammoniac nitrogen, nitric nitrogen, and total nitrogen (T-N) in stream water, treatment water from sewage and wastewater treatment facility, wastewater from anaerobic digestion tank, factory effluent, etc. |
