In summary, we discuss two prevailing trends for modeling transport-coupled kinetics in heterogeneous electrocatalysis. The two approaches generally differ in the target scientific questions that they aim to answer and, hence, in whether the larger focus is put on the description of the catalytic surface kinetics or mass transport. While the value of each of these models is easily demonstrated through many notable studies in the existing literature, remaining practical and methodological challenges are cur-rently the object of ongoing research. Such efforts include, for example, developments towards a more systematic fitting of BV parameters as well as the exploration of improved phenomenological kinetic models such as, e.g., the Marcus-Hush-Chidsey model . Simultaneously, in the realm of 1p-mkm, extensive methodological work is presently being devoted to advancing simulations of the working electrochemical interface while providing constant-potential energies and barriers . Most noteworthy are also efforts toward an automatic exploration of reaction networks using machine learning . Promising research along this direction aims to lift the bias in assuming a catalytic mechanism which is usually based on chemical intuition.
