Highly active photocatalytic asphalt pavement for NOx removal using iron-doped g-C3N4
Low degradation efficiency limited the application of photocatalytic material in pavement construction. In this study, iron-doped g-C 3 N 4 (Fe-C 3 N 4 ) method was introduced to prepare a high active photocatalyst. The crystal structure and electronic structure of the Fe-C 3 N 4 were calculated by...
