Electrochemically grown Cu,Ni-BTC film for the electrochemical detection of caffeic acid in fruits.

ABSTRACT: Caffeic acid (CA) is an important antioxidant often found in many kinds of fruits. In this study, we developed an electrochemical sensor based on an electrochemically grown bimetallic metal-organic framework film (Cu,Ni-BTC) for the in situ determination of CA in fruits. The Cu,Ni-BTC film was grown directly onto a glassy carbon electrode (GCE) via a cathodic electrodeposition method under optimal conditions. The results showed that a uniform film made of Cu,Ni-BTC metal-organic frameworks with a Cu : Ni molar ratio of 3.67 was grown on the electrode surface. It was found that the charge transfer kinetics were much improved on the electrode modified with the Cu,Ni-BTC material. Consequently, the caffeic acid sensor based on the Cu,Ni-BTC film showed a detection limit and sens
