Metal Oxide Alternatives Used in Chlorine Reduction to Hypochlorite for Nitrate Reduction Process

This study uses DFT to find the reaction path of chlorine reduction to hypochlorite on various metal oxides in hopes of finding a less expensive catalyst for chlorine reduction than IrO2. The metal oxide alternatives should be stable, have a band gap of zero, and have a tetragonal structure in order to closely resemble IrO2. Currently, the three metals tested are RuO2, RhO2, and CrO2. Hypochlorite can then be further used in a reaction with ammonia to remove nitrate from water by reducing it into nitrogen gas.
