Two-dimensional (2D) nanomaterials have attracted interest in recent times due to their promise in various applications. Carbon structures have been extensively studied over recent decades as energy storage materials. One of the industry applications is as the anode of lithium (Li) ion batteries. A high surface to area ratio also makes graphene attractive as a gas sensing material.

Here we will present our recent work on carbon nitride materials for Li ion battery anode materials and sensing. We have shown that experimentally synthesized carbon nitride 2D materials such as g-C3N4, g-CN (g-C3N3) and hC2N form strong ionic bonds with Li and have a high Li storage capacity. They also induce a large charge transfer from the Li to the material.1-4 In a recent study we also showed that these 2D materials are excellent for sensing of NH3 and H2S due to a large change in their band gap, while the electronic structure remains unchanged in the presence of CH4, CO2 and SO2 for example.5
