Abstract
The present application relates to a system for removal of nitrate from water. The system includes a first reactor comprising a porous oxide-derived silver electrode (OD-Ag) for electrocatalytic reduction of nitrate (NO3−) to nitrite (NO2−) and a second reactor comprising a Pd-based catalyst for catalytic reduction of nitrite (NO2−). Also disclosed is a method of removing nitrate from water.
