“…As a result, FG is regarded as a potential candidate in gas detection, storage, and separation. [98,[207][208][209][210][211][212] Liu et al displayed that FG showed a distinct color variation from white to dark yellow under the atmosphere of ammonia, which could be observed with naked eyes directly. The corresponding sensitivity reached a high value of 4.05% by PL measurement.…”

“…The investigation of other types of graphenes showed interesting results and reflect the potential of these materials for ammonia detection. Fluorinated graphene has been extensively studied for ammonia detection [ 100 , 180 , 196 ], since it contains electronegative F atoms, and their interaction with hydrogen is one of the strongest interactions that occur in hydrogen bonding, therefore enhancing the adsorption of gases [ 197 ]. The absorption energy of fluorographene was significantly higher than that of graphene (0.137 and 0.026 eV, respectively) [ 197 ].…”

This review paper is devoted to an extended analysis of ammonia gas sensors based on carbon nanomaterials. It provides a detailed comparison of various types of active materials used for the detection of ammonia, e.g., carbon nanotubes, carbon nanofibers, graphene, graphene oxide, and related materials. Different parameters that can affect the performance of chemiresistive gas sensors are discussed. The paper also gives a comparison of the sensing characteristics (response, response time, recovery time, operating temperature) of gas sensors based on carbon nanomaterials. The results of our tests on ammonia gas sensors using various techniques are analyzed. The problems related to the recovery of sensors using various approaches are also considered. Finally, the impact of relative humidity on the sensing behavior of carbon nanomaterials of various different natures was estimated.

“…Among processes for gas sensing improvement such as acid treatments [134,135], plasma ones [136,137], functionalisation with polymers [138], decoration with nanoparticles [139,140], etc. [141], fluorination exhibits numerous advantages [142][143][144]. In particular, it increases the SSA of carbon nanomaterials [145].…”
