Abstract
An electrochemical sensor based on MXene/PANI/SnO2 nanomaterials was developed for the detection of 4-aminophenol (4-AP). In situ oxidative growth of PANI on the MXene surface effectively hindered the stacking of the lamellae and increased the specific surface area of the composites. Further complexation of tin dioxide with swelling properties of the structure provided adsorption and catalytic sites for 4-AP. The prepared electrochemical sensor displayed good Linearity in the concentration range 0.50 ~ 115.38 µM and low detection limit (LOD = 0.19 µM). The sensor also had good reproducibility and stability. The MXene/PANI/SnO2/GCE sensor was applied to the determination of tablets and Yellow River water, and expressed high recoveries and low relative standard deviations.
期刊介绍：
As a peer-reviewed journal for analytical sciences and technologies on the micro- and nanoscale, Microchimica Acta has established itself as a premier forum for truly novel approaches in chemical and biochemical analysis. Coverage includes methods and devices that provide expedient solutions to the most contemporary demands in this area. Examples are point-of-care technologies, wearable (bio)sensors, in-vivo-monitoring, micro/nanomotors and materials based on synthetic biology as well as biomedical imaging and targeting.
