ABSTRACT Raney Ni, a porous Ni catalyst derived from alkali‐leached Ni–Al alloy, has anchored itself in the field of catalysis for a century since its 1924 invention by Raney. Its dual merits—high activity and in situ hydrogen storage—enable applications in various fields. This review condenses its evolution: from alloy design to functional tailoring via doping/milling, emphasizing structure–activity correlations and sustainable chemistry impacts. Despite its long‐standing utility, comprehensive reviews on Raney Ni's century‐long evolution have been scarce. This review systematically summarizes its development—from discovery and preparation refinement to performance modification and application expansion—highlighting its enduring role in catalysis and providing insights for future sustainable material research.
