摘要

Carbon nitride/reduced graphene oxide (rGO) van der Waals heterostructures (vdWH) have previously shown exceptional oxygen sensitivity via a photoredox mechanism, making it a potential material candidate for various applications such as oxygen reduction reaction catalysis and oxygen sensing. In this work, the electronic structure of a carbon nitride/rGO composite is modified through the introduction of copper nanoparticles (NPs). When incorporated into a chemiresistor device, this vdWH displayed a newfound CO_(2) sensitivity. The effects of humidity and light were investigated and found to be crucial components for the CO_(2) sensitivity. Density functional theory calculations performed on a carbon nitride/copper [email?protected] model system found an enhanced stabilization of CO_(2) caused by H-bonds between the carbon nitride layer and chemisorbed CO_(2) on copper, pointing to the important role played by humidity. The synergetic effect between the carbon nitride layer interfaced with [email?protected], in combination with humidity and light (395 nm) irradiation, is found to be responsible for the newfound sensitivity toward CO_(2).
