Abstract

Herein, we synthesized hydrothermally Fe3O4 nanoparticles (NPs) and investigated their catalytic performance in NaBH₄ methanolysis for hydrogen generation. Key parameters, including the NaBH4 concentration, catalyst loading, and temperature, were optimized. Comprehensive characterization via XRD,SEM, EDX, FTIR, and BET revealed the surface properties of the catalyst. The optimized catalyst exhibited an outstanding HGR of 2721.9 ml gcat⁻¹ min⁻¹ at 30°C with an Ea of 27.18 kJ mol⁻¹. FE-SEM analysis indicated particle agglomeration with a size distribution of 200 nm, whereas the BET data demonstrated a moderate surface area of 37.17 m² g⁻¹ and pore diameter of 13.24 nm. Remarkably, the catalyst maintained 99% efficiency after six reuse cycles, emphasizing its industrial viability and long-term stability.
