Gas sensors are an integral part of everyday life. New materials and manufacturing processes enable the production of smaller, more accurate, cheaper and more selective sensors. Compared to pure material, heterostructured or hybrid sensors allow the combination of materials’ parameters and show improved response, selectivity and reproducibility. Heterostructures consisting of nanocrystalline diamond (NCD), molybdenum disulfide (MoS2) and graphene oxide (GO) have been investigated as gas sensors that operate at room temperature and have built-in interdigital metal electrode structures to measure conductivity. The fabrication of heterostructures of MoS2/NCD, rGO/NCD or GO-SH/NCD using suitable physical/chemical deposition methods is demonstrated. Furthermore, the measured sensor parameters of the tested materials and their heterostructures, in particular response, response rate, stability and regeneration, are compared and critically evaluated.
