• • Achieved a turnover frequency (TOF) of 57.23 min−1 for ammonia borane hydrolysis at 298 K, outperforming many non-noble metal catalysts and approaching noble metal benchmarks, indicating high intrinsic activity for practical hydrogen production.
• • Apparent activation energy of 44.31 kJ/mol, which is low enough to enable efficient hydrogen release under mild conditions, reducing energy input for industrial processes.
• • The catalyst follows pseudo-first-order kinetics with respect to catalyst amount and pseudo-zero-order kinetics with respect to AB concentration, enabling predictable scaling and reactor design.
• • The synthesis uses low-cost copper chloride and sodium hypophosphite via solvothermal and low-temperature phosphating (573 K, 2 h), offering a scalable, cost-effective route for catalyst production, critical for industrial adoption.
