Negative reduction potential

The electrode potential for a reduction reaction can be read straight from the table. The electrode potential for an oxidation reaction will have the opposite sign to the one given in the table, that is if E o for the reduction reaction is positive then it will be negative for the oxidation reaction. .

Since the obtaining of useful energy in a biological process generally involves oxidation of some foodstuff, it follows that a large negative redox potential like -0.32 V for NAD + suggests a useful role in producing a reduced product, like NADH. A reduced coenzyme NADH can be oxidized to provide energy for biological processes.The emerging electrochemical nitric oxide reaction reduction (NORR) has received great attention due to its 2-fold functions in producing NH3 and eliminating toxic NO molecule. However, developing applicable NORR electrocatalysts with good stability and low-cost features remains challenging. Herein, we combine density functional theory (DFT) and a descriptor-based method to study the catalytic ...
