Highly sensitive detection of cephradine based on three-dimensional honeycomb-like porous nano-silver

In this paper, three-dimensional honeycomb-like porous nano-silver (3DHPNS) were prepared by one-step potentiostatic deposition on bare gold electrode by using dynamic bubble template method. The electrochemical behavior of 3DHPNS modified Au (3DHPNS/Au) electrode in 0.1 M phosphoric acid buffer solution (pH=7.0) was studied, and the electrocatalytic properties and sensing properties of cephradine (CEP) on the 3DHPNS/Au electrode were investigated. Due to the large specific surface area and high porosity of 3DHPNS, which can supply more catalytic active sites and accelerate the mass transfer rate, the 3DHPNS/Au electrode show superior electrocatalytic activity and sensing performance of CEP
