To develop structure–activity connections and identify rate-limiting stages under various operating regimes, thermodynamic, kinetic, and fundamental reaction processes are examined. Ru-based catalysts, especially those supported on conductive carbons and tailored perovskites, are standards for low-temperature activity, but their high cost and stability prevent large-scale application. Combining Ni-based catalysts with Al<sub>2</sub>O<sub>3</sub> or basic perovskite supports offers a good balance between activity, cost, and commercial practicality, making them the dominant non-noble alternatives. Due to strong metal–support interactions and alternate reaction routes, Co-based catalysts in perovskite formulations seem promising despite being inherently less active.
