Abstract Electrochemical thermodynamics establishes the relationship between the reversible battery electric potential and the corresponding battery reaction thermodynamic function. Electrochemical oxidation of 5-hydroxymethyl furfural (5-HMF) to produce 2,5-furandicarboxylic acid (FDCA) can replace the traditional polyethylene terephthalate (PET) route for preparation of bio-derived plastics, but no accurate experimental data are available for the standard electric potential of the reaction and the standard reversible electrode potential of each step. In this paper, these data are calculated by the literature thermodynamic data. The results confirmed that the oxidation reaction of HMF occurs first than the oxidation reaction of water in terms of both thermodynamics and electrochemistry, and the electrochemical oxidation of HMF is easier to proceed in a strong alkaline solution. The obtained data can be added to the electrochemical tool books as reference. The work is introduced as a comprehensive exercise into the teaching of electrochemical thermodynamics. It helps to deepen the understanding on the relationship among various parts of physical chemistry, improves students’ ability to apply physical and chemical knowledge to solve practical problems.
