- Abstract
We successfully synthesized quaternary nanocomposites containing CuZnSnSe semiconductors combined with graphene-based polymers for selective gas sensing and analyzed their cross-sensitivity using cyclic voltammetry. To investigate the selectivity of graphene-polymer-based detection of different gases was performed for Ammonia (NH3), oxygen (O2), carbon dioxide (CO2), into an emptied vacuum chamber. The sensors provide a direct accurate transformation into electrical signals in devices by recognizing CO2, O2, and NH3. It shows that the sensor has a high selectivity to CO2 by distinguishing with O2, NH3 in vapor-phase intelligently with accurate transformation into electrical signals in devices. Finally, the CuZnSnSe-G-PPy sensors demonstrate fast response/recovery times and a wide range of CO2, O2, NH3 detection. The superior sensing ability of mesoporous CuZnSnSe-G-PPy compared to CuZnSnSe-G and CuZnSnSe eventually is due to the implied optimum amount of synthesized sample. Finally, we proved a facile, low-cost route for the assembly of multiple gas-sensing devices with the potential for vast application.
