“…There are several catalysts that can be used to enhance the rate of hydrogen release from sodium borohydride, including metal oxide catalysts such as Fe 2 O 3 [24], NiO [25], and Co 3 O 4 [26]. These studies suggest that high surface area and small particle size of the metal oxides can enhance the reaction rate and hydrogen production yield.…”

The synthesis of CaCO3/Cu2O/GO nanocomposites was developed by sol-gel auto-combustion method. The analysis of structure was completed on X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), Raman spectroscopy, and environmental scanning electron microscopy (ESEM). The XRD spectra of the nanocomposites matched the crystal structure of CaCO3/Cu2O. The average crystal size was 20 nm for Cu2O and 25 nm for CaCO3 nanoparticles. FTIR data showed the absorption bands of Cu2O and GO. Raman spectroscopy data confirmed the formation of GO sheets. ESEM micrographs displayed spherical nanoparticles dispersed in GO sheets. X-ray photoelectron spectroscopy showed the peaks of Cu 2p, O 1s, C 1s, Cu 3s, and Ca 2p. The spectra of optical absorption revealed an absorption band of around 450 nm. The calcium content increase led to a decrease in the optical energy gap from 2.14 to 1.5 eV. The production of hydrogen from NaBH4 across the methanolysis reaction was accelerated by the CaCO3/Cu2O/GO nanocomposites. Therefore, these nanocomposites are superior in catalytic hydrogen production systems.

“…Examples of the most popular chemical hydrides are NaBH 4 , NH 3, and MgH 2 . Borohydrides such as NaBH 4 are preferred due to their environmental friendliness, non-flammability, and stability in alkaline solutions [4]. A popular way to obtain hydrogen is using sodium boron hydride (NaBH 4 ) which is a purposive hydrogen carrier.…”

In this study, hydrolysis reaction performances of raw BFS powder and metal powders (which are ingredients of BFS) that are using as a catalyst are compared. Hydrogen generation by hydrolysis reaction of the Al and Fe2O3 Nano & Granule powders with sodium borohydride (NaBH4) addition in water was studied by using different catalysts amount at reaction vessels. The measured values of reaction temperatures and hydrogen flow rates were measured by using high-precision equipment. As a result of the obtained data, it was determined that Fe2O3 and Al catalysts have advantages over hydrogen production rate and fuel conversion, also, these experiments show a very high success in different parameters, and create promising effects in the reactions. Among the Al catalyst samples, the highest efficiency performances are achieved with Al Nano catalyst samples at 85.31 °C preheat with an instantaneous hydrogen generation rate of approximately 11.226 L / min for 33 minutes. Among the Fe2O3 catalyst samples, the highest efficiency performances are achieved with Fe2O3 Nano catalyst samples at 50 °C preheat with an instantaneous hydrogen generation rate of approximately 29.91 L / min for 12 minutes.

The PdRu/C electrocatalysts were synthesized by the sodium borohydride reduction method, with 20% of the metallic load. The metal nanoparticles were supported on Carbo Vulcan XC-72, loading to different Pd:Ru mass proportions. The electrocatalysts obtained in this work were characterized by X-ray dispersive energy spectroscopy (EDX), X-ray diffraction (DRX), transmission electron microscopy (TEM), X-ray excited photoelectron spectroscopy (XPS), Fourier-transform infrared spectroscopy (ATR-FTIR), cyclic voltammetry and chronoamperometry. It also applied to direct-ethanol and glycerol fuel cells (DEFC and DGFC). The characterization by EDX allowed us to obtain information about the respect of the atomic composition of the material under study. XRD spectra for all PdRu / C electrocatalysts indicate a shift from the Pd peak (fcc) relative to the plane (220) to higher 2θ values. Histograms achieved by counting nanoparticles recorded by TEM for PdRu/C showing homogeneous nanoparticles and distributed on the support with sizes between 2.9 and 6.5 nm. The XPS results revealed different oxidation states (Ru 0 and RuO2) in which they favor oxidation of adsorbed intermediate species, through the bifunctional mechanism. The PdRu/C electrocatalyst (90:10) demonstrated the best performance for the electrocatalytic oxidation of ethanol and glycerol, observing the analyzes of linear voltammetry and chronoamperometry, however, in the tests using direct-ethanol and glycerol fuel
