Exploring the Application of Graphene Composite Nanomaterials in Electrochemical Sensing
The article proposes a simple preparation method for AuNPs/GAQ nanocomposites and constructs a paired PQ electrochemical sensor based on this method.At the same time,the performance of the electrochemical reactor based on AuNPs/GAQ nanocomposites was analyzed from the aspects of the electrochemical behavior of PQ on the modified electrode,linear range and detection limit,and material properties,and further verified by the detection of PQ in water samples.The results indicate that in actual PQ redox reactions,the electrocatalytic activity exhibited by AuNPs/GAQ is extremely ideal;Compared with other types of modified electrodes,the linear range of AuNPs/GAQ is wider and the detection limit is lower;This electrochemical sensor can achieve good results in the fast and accurate detection of PQ in actual groundwater samples.
