  "abstract": "Machine learning (ML) is transforming the discovery of electrocatalysts for the carbon-neutral energy transition by overcoming the limitations of trial-and-error experimentation and costly quantum simulations. This review summarizes recent advances in data-driven electrocatalysis, focusing on two emerging paradigm shifts: autonomous literature mining assisted by large language models (LLMs) and materials representation via graph neural networks (GNNs). We first trace the evolution from manual data curation to LLM-assisted mining, which accelerates database construction by orders of magnitude; then, the shift from handcrafted descriptors to GNNs, which expands the computational screening space from thousands to millions of candidates. Subsequently, we discuss key algorithms—including active learning and symbolic regression—and their applications in the hydrogen evolution reaction (HER), oxygen evolution reaction, oxygen reduction reaction, and carbon dioxide reduction reaction, illustrating how they help identify non-intuitive descriptors that rationalize activity trends. We also highlight how these descriptor-based predictions guide the discovery of specific catalyst motifs or reaction pathways that can circumvent or break complex scaling relations inherent in multi-electron transfer processes. We then critically discuss challenges related to data heterogeneity, model interpretability, and the synthesis–performance gap, before offering a perspective on integrating physics-informed ML and autonomous self-driving laboratories to accelerate the rational design of next-generation electrocatalysts.",
