Nanomaterials‐based gas sensors of SF ₆ decomposed species for evaluating the operation status of high‐voltage insulation devices

In recent years, many novel sensing nanomaterials were explored experimentally and theoretically as chemical gas sensors to detect sulphur hexafluoride (SF6) decomposed species with rapid response, high sensitivity and selectivity, as well as low cost, in order to estimate and guarantee the operation status of SF6 insulation devices. However, there has been no systemic review yet to comprehensively understand their sensing mechanism and conclude...
