Effect of interlaced energy bands in polymeric carbon nitride nanotubes on the greatly enhanced visible-light photocatalytic hydrogen evolution

The microstructure design of polymeric carbon nitride (PCN) has been proved to promote the interlayer transport of photogenerated electron, but its influence mechanism is still not unequivocal. Herein, based on the PCN nanotube model with actual thickness, we proposed a novel mechanism by density functional theory (DFT) calculation, which explained the effect of the nanotube structure of photogenerated electron interlayer transport. The...
