Hydrogen is considered a clean energy transport due to its high energy density, environmental friendliness, high efficiency, and recyclable nature. This study generated hydrogen through NaBH 4 ethanolysis. In hydrogen production studies, there are very few studies with magnetic nano catalysts and very few studies with cheap transition metals. In order to contribute to the literature in this field, in this study, Fe 3 O 4 @SiO 2 @EDDHA-Fe was produced for the first time and used in hydrogen production studies. Fe 3 O 4 @SiO 2 @EDDHA-Fe synthesis was successfully carried out and hydrogen production was successfully implemented. The study also utilized FT-IR, XRD, VSM, BET, and SEM-EDX methods to characterize the structural, physical, and chemical properties of MNCs. The average particle diameter and magnetization value of Fe 3 O 4 @SiO 2 @EDDHA-Fe were 12.81 nm and 30.6 emu/g, respectively. The catalysis experiment designed with 50 mg Fe 3 O 4 @SiO 2 @EDDHA-Fe and 93.75 mM NaBH 4 generated 840 mL H 2 /g NaBH 4 298 K and 947 mL H 2 /g NaBH 4 318 K in 5 -min duration, respectively. At room temperature, the hydrogen generation rate (HGR) and activation energy (Ea) of Fe 3 O 4 @SiO 2 @EDDHA-Fe reaction were calculated as 1040 mL H 2 /gcat & sdot; min and 5.39 kJ/mol, respectively. After the sixth cycle, the reusability test of Fe 3 O 4 @SiO 2 @EDDHA-Fe reaction still retained approximately 87% of the initial hydrogen production volume. The study concluded that Fe 3 O 4 @SiO 2 @EDDHA- Fe is a promising catalyst in hydrogen production from NaBH 4 ethanolysis, as it is affordable and easy to prepare compared to other expensive catalysts.en10.1016/j.ceramint.2024.02.309info:eu-repo/semantics/closedAccessEthanolysisHydrogen ProductionKinetic StudyMagnetic Nano-CatalystSodium BorohydrideArticle50111825818268Q1Q1WOS:0012338595000012-s2.0-851871742844
