abstract = {Experimental and theoretical investigation of the capacity of the natural ilmenite (FeTiO3) to reduce nitrate (NO3−) from ultra-pure and mineral water is presented. A comprehensive mechanism of NO3− photocatalytic transformation is proposed regarding the density functional theory (DFT) calculations and the photocatalytic reduction of nitrate. When ultra-pure water is employed, the nitrate is totally converted to NOX (2%) and N2 (98%) after 210 min. Additionally, using the stoichiometric dose of oxalate, the nitrate also vanishes from the mineral water, forming NO2−, NOX, and N2 as products. Thus, the findings reveal that natural ilmenite can be a great candidate for reducing NO3− in contaminated water.},
