Abstract

Nitrogen fixation is a natural or artificial process, in which molecular nitrogen is combined with other elements to form more-reactive compounds containing nitrogen elements. In this study, graphitic carbon nitride nanosheets were combined with nanoparticles of MgO to fabricate an efficient binary visible-light-induced photocatalysts (abbreviated as NCN/MgO), and they were applied for the photofixation of nitrogen gas. The synthesized photocatalysts were characterized to investigate the morphology, phase structure, optical, and textural properties. The results displayed that the NCN/MgO (10%) nanocomposite has considerable performance in the nitrogen photofixation reaction compared with the pristine CN and NCN, which is 10.8 and 2.8 times, respectively. The stability of the optimum sample, as a vital characteristic of photocatalyst, was examined in three runs. Also, the effect of MgO loading, calcination temperature, solvent, electron scavenger, pH, and absence of N-2 in solution upon the NH4+ production rate was examined. Finally, an anticipated mechanism was proposed for the meaningful nitrogen photofixation enhancement. (C) 2020 The Korean Society of Industrial and Engineering Chemistry. Published by Elsevier B.V.
