Abstract

Abstract : P-doped TiO2 nanobelt array supported on titanium plate acts as a high efficiency electrocatalyst for NO2 − reduction reaction, attaining a satisfactory faradaic efficiency of 90.6% and a large NH3 yield as high as 560.8 μmol h −1 cm −2 . Abstract : Electrochemical nitrite reduction affords an eco-friendly route for the removal of hazardous NO2 − and sustainable NH3 synthesis. Here, we report that a P-doped TiO2 nanobelt array supported on titanium plate (P-TiO2 /TP) acts as a high-efficiency electrocatalyst for the NO2 − reduction reaction, attaining a satisfactory faradaic efficiency of 90.6% and a large NH3 yield as high as 560.8 μmol h −1 cm −2, superior to pristine TiO2 /TP. Moreover, the catalytic mechanism involved is also uncovered by theoretical calculation.
