Harnessing Microexplosions for Rapid Pd–N Single‐Atom Catalyst Formation

SACs demonstrate exceptional activity and stability (>200 h) in the hydrogenation of biomass-derived 5-hydroxymethylfurfural (HMF), outperforming nanoparticle benchmarks by 2-3 orders of magnitude due to optimized electronic structure and maximized active site accessibility. Remarkably, the MER process reduces energy consumption by 98% compared to pyrolysis methods and enables scalable production (kilogram-level) with batch-to-batch consistency. This strategy is universally applicable to 8 metals (e.g., Pd, Pt, Co), establishing a fundamental and practical platform for sustainable SAC manufacturing with minimized carbon footprint.
