RESUMO:

A hydrogen generation system based on sodium borohydride hydrolysis (NaBH₄) was developed using catalysts derived from residual biomass, specifically sugarcane bagasse. The successful synthesis of MOB catalysts with high stability was confirmed through characterization techniques, including FTIR, XRD, XRF, TGA, SEM, and GC, which verified positive structural modifications. The Taguchi method was applied to optimize the process and reduce the number of experiments. The factors that statistically contributed the most within the model's confidence range were time (35 minutes), NaBH₄ (750 mg), and MOB (300 mg), with NaBH₄ standing out at 58.87% and the MOB catalyst contributing 27.03% to hydrogen production. Additionally, the integration with a photovoltaic solar energy network demonstrated energy viability, with a total consumption of 614.5 kWh to produce 1.000 mL of H₂. The results show that MOB exhibits superior catalytic performance for NaBH₄ hydrolysis, with excellent economic feasibility. This catalyst is highly promising for practical applications in NaBH₄ hydrolysis.
