Electro‐membrane reactors use electro‐membranes for preferentially diffusive/electrophoretic migration or electroosmotic separation of in‐situ reactive products, thereby maximizing the reaction rate and transport efficiencies of the products. These reactors are widely employed in the chemical engineering sectors such as green chemical synthesis, biorefining, electrocatalytic reduction/oxidation, and water treatment. In this review article, we provide an overview of the recent advances in three categories of electro‐membrane reactors in chemical engineering sectors from three categories: (1) Electro‐membrane reactors based on stacked ion‐exchange membranes for resources recovery; (2) Electro‐membrane reactors via Faraday reactions on functional anodes/cathodes for substance transformation; and (3) Closed‐loop chemical reactions and substance separation via coupling of Faraday reactions and stacked membranes. The increasing demand for low‐carbon economy has accelerated the advancement of environmentally friendly chemical engineering and sustainable processes and necessitates the use of electro‐membrane processes. The macro perspective provides a timely reference for researchers and engineers.

Electrocatalytic nitrite reduction (e‐NO2−RR) offers an attractive strategy for industrial green ammonia synthesis. The understanding of electrochemical kinetics is the core to guarantee the efficient operation of e‐NO2−RR system. However, the application of the widely used Butler–Volmer equation should be restricted to the constraint of non‐mass transfer effects. In this work, an electrochemical macrokinetics equation for mass transfer restriction region was developed based on the traditional macrokinetics thought, which combined the Practical Butler–Volmer equation and Nernst‐Plank equation. The model validation was carried out by the combination of multiphysics‐field simulation, computational fluid dynamics simulation and experiments, and the results show that the average relative error between experiments and simulations is less than 2%. The results in this article contribute to an in‐depth understanding of the kinetics behavior for e‐NO2−RR and achieve the extension of electrochemical kinetics equation from non‐mass transfer restriction region to mass transfer restriction region.
