RR, and NRR. Special attention is given to how controlled strain optimizes intermediate adsorption energies in accordance with the Sabatier principle, thereby enhancing catalytic activity, selectivity, and durability. Finally, we discuss the remaining challenges in controlling strain magnitude, stability, and scalability, and outline perspectives for integrating strain engineering with other design principles. This review establishes lattice strain as a unifying and predictive framework for rational catalyst design, paving the way for high-performance electrocatalysts in sustainable energy conversion and storage technologies.
