Efficient electrocatalyst development is crucial for addressing global energy challenges, and recent advances have highlighted the significant role of electron spin-a fundamental property of electrons-in influencing catalytic processes. Regulating the spin states of active sites has emerged as a powerful strategy to enhance catalytic performance. In response to growing interest in spin-induced electrocatalysis, this review offers a comprehensive examination of the impact of spin states on electrocatalytic activity. We explore various strategies for modulating spin states, review state-of-the-art techniques for spin state characterization, and elucidate the mechanisms by which spin effects enhance catalytic efficiency. Additionally, we discuss future research directions, emphasizing the potential of spin regulation to drive innovation in electrocatalyst design and application. This review aims to provide a foundational understanding of spin effects in electrocatalysis, guiding future efforts in the rational design of high-performance catalysts.
