Electroreduction of NO3− on tubular porous Ti electrodes
Tubular porous Ti electrodes convert nitrate to ammonia with 58% faradaic efficiency and −33 mA cm⁻² partial current density, rising to −75 mA cm⁻² with inert gas flow through the hollow fiber wall. EC-MS additionally identifies hydroxylamine, NO, and N₂O as byproducts — pointing toward a viable route for agricultural nitrate recycling.
