Özet
This current study reports the synthesis, characterization, and optimization of a novel catalyst (Ac-HCl-Fe) derived from Acorn cups biomass waste for hydrogen production via sodium borohydride (NaBH₄) solvolysis. The catalyst characterization was conducted using FTIR, SEM, and SEM-EDX techniques. Catalytic performance tests showed the efficiency of Ac-HCl-Fe in hydrogen generation, with parameters including catalyst loading, NaBH₄ quantity, and reaction temperature significantly influencing the kinetics. Remarkably, the NaBH₄ methanolysis reaction catalyzed by Ac-HCl-Fe was completed in 4.0 minutes, while the NaBH4 solvolysis in a binary propylene glycol/methanol (1:1, v/v) solvent system reached completion within just 0.9 minutes, producing a similar volume of hydrogen (~670 mL). The HGR was determined to be 68,300 mL min⁻¹gcat⁻¹ for the NaBH₄ solvolysis reaction conducted in a binary propylene glycol/methanol (1:1, v/v) solvent system at 30 °C. In addition, the effective activation energy was calculated to be 32.36 kJ/mol, that is relatively low compared to other activated carbon-based catalysts reported for similar applications. Overall, the results show that Ac-HCl-Fe is a promising, efficient, and sustainable catalyst for hydrogen generation by solvolysis of NaBH₄, especially in binary solvent systems.
