Photocatalytic hydrogen production and storage in carbon nanotubes: a first-principles study

Year: 2022

Type: article

Abstract: photocatalytic processes. We considered a core-shell structure formed by placing a carbon nitride nanowire inside a carbon nanotube to achieve this goal. Photo-generated holes on the carbon nanotube surface promote water splitting. Driven by intrinsic electrostatic field in the core-shell structures, protons produced by water splitting penetrate the carbon nanotube and react with photo-generated electrons on the carbon nitride nanowire to produce hydrogen molecules in the carbon nanotube. Because carbon nanotubes have high hydrogen storage capacity, this core-shell structure can serve as a candidate system for photocatalytic water splitting and safe hydrogen storage.
