Electrochemical sensor based on nano-matrix loaded bimetallic catalyst, and manufacturing method and application thereof

The invention discloses an electrochemical sensor based on a nano-matrix loaded bimetallic catalyst, and a manufacturing method and application thereof. The electrochemical sensor comprises an electrochemical workstation, the electrochemical workstation is connected with a working electrode, a counter electrode and a reference electrode, and the working electrode is a GCErGO-Cu/Ni electrode. The preparation of the rGO-Cu/Ni compound on the surface of the working electrode can be achieved by innovatively adopting a one-step electrochemical code position method. The method can provide a new idea for large-scale, simple, low-cost, in-situ and controllable acquisition of nano composite materials, and can develop a new way for construction of a new generation of nano-structure electrochemical sensor devices. The constructed glucose electrochemical sensor can realize high-sensitivity and high-selectivity detection of glucose content through one-time sample injection, and is suitable for high-flux and low-cost analy
