Abstract: We provide a critical review of the current state of the synthesis and applications of nano- and micro-tubes of layeredgraphitic carbon nitride. This emerging material has a huge potential for light-harvesting applications, including lightsensing, artificial photosynthesis, selective photocatalysis, hydrogen storage, light-induced motion, membranetechnologies, and can become a major competitor for such established materials as carbon and titania dioxide nanotubes.Graphitic carbon nitride tubes (GCNTs) combine visible-light sensitivity, high charge carrier mobility, and exceptionalchemical/photochemical stability, imparting this material with unrivaled photocatalytic activities in photosyntheticprocesses, such as water splitting and carbon dioxide reduction. The unique geometric GCNT structure and versatility ofpossible chemical modifications allow new photocatalytic applications of GCNTs to be envisaged including selectivephotocatalysts of multi-electron processes as well as light-induced and light-directed motion of GCNT-basedmicroswimmers. Closely-packed arrays of aligned GCNTs show great promise as multifunctional membrane materials forthe light energy conversion and storage, light-driven pumping of liquids, selective adsorption, and electrochemicalapplications. These emerging applications require synthetic routes to GCNTs with highly controlled morphologicalparameters and composition to be available. We recognize three major strategies for the GCNT synthesis includingtemplating, supramolecular assemblying of precursors, and scrolling of nano-/microsheets, and outline promising routesfor further progress of these approaches in the light of the most important emerging applications of GCNTs.
