文摘

Nitrate photocatalysis with formic acid efficient over different TiO2 samples. Nitrite, ammonium, non-identified nitrogen compounds produced during the reaction. Radiolytically prepared Ag-TiO2 samples more efficient than unmodified TiO2. Modification of TiO2 samples with Pd deteriorates NO3− transformation. A mechanism of photocatalytic nitrate transformation is proposed.
