| Abstract: | Hydrogen generation from sodium borohydride (NaBH 4) hydrolysis in the presence of metal catalysts is a frequently used and encouraging method for hydrogen storage. Metal nanoparticle-supported catalysts are better recyclability and dispersion than unsupported metal catalysts. In this study, the synthesis and characterization of a polymer-supported catalyst for hydrogen generation using NaBH 4 have been investigated. For the synthesis of polymeric material, first of all, kaolin (KLN) clay has been magnetically rendered by using the co-precipitation method (Fe 3 O 4 @KLN) and then coated with poly tannic acid (PTA@Fe 3 O 4 @KLN). Then, the catalyst loaded with cobalt (Co) nanoparticles have been obtained with the NaBH 4 reduction method (Co@PTA@Fe 3 O 4 @KLN). The surface morphology and structural properties of the prepared catalysts have been determined using methods such as scanning electron microscopy (SEM), Fourier transform infrared spectroscopy (FT-IR), X-ray powder diffraction (XRD), X-ray photoelectron spectroscopy (XPS), inductively coupled plasma mass spectrometry (ICP-MS) and vibrating sample magnetometer (VSM). The optimization of the most important variables (NaBH 4 amount, NaOH amount, catalyst amount, and metal loading rate) affecting the hydrolysis of NaBH 4 using the synthesized polymeric catalysts was carried out using response surface methodology (RSM). Depending on the evaluated parameters, the desired response was determined to be hydrogen production rate (HGR, mL/g min). HGR was 1540.4 mL/g cat. min. in the presence of the Co@PTA@Fe 3 O 4 @KLN at optimum points obtained via RSM (NaBH 4 amount 0.34 M, NaOH amount 7.9 wt%, catalyst amount 3.84 mg/mL, and Co loading rate 6.1%). The reusability performance of the catalyst used in hydrolysis of NaBH 4 was investigated under optimum conditions. It was concluded that the catalyst is quite stable. [Display omitted] • PTA@Fe 3 O 4 @KLN supported Co NPs were successfully synthesized. • Four parameters affecting H 2 production were optimized using RSM. • Fast H 2 production rate (1540.4 mL/g cat. min.) was achieved per mass of catalyst. • The activation energy was found to be 31.85 kJ/mol with Co@PTA@Fe 3 O 4 @KLN. • The catalyst was magnetically recoverable and showed high activity after five cycles.
