Carbon vacancy in C3N4 nanotube: Electronic structure, photocatalysis mechanism and highly enhanced activity

[Display omitted] •Tubular g-C3N4 with carbon vacancy was obtained by pyrolysis under N2 atmosphere.•Carbon vacancy facilitates the adsorption of NO and O2 on the surface of g-C3N4.•Carbon vacancy accelerates the separation and transfer of photo-generated carriers.•g-C3N4 with carbon vacancy exhibit...
