Summary: In the study, it was found that cobalt catalysts are more active than nickel catalysts in the hydrolysis of sodium borohydride. One reason for the lower activity of nickel catalysts is the presence of hydrogen on its surface, which interferes with reactant adsorption. The addition of cobalt to nickel catalysts can enhance hydrogen generation rate.

Summary: Developing nonprecious metal catalysts with fast charge transferability, abundant active sites, and easy recovery is important for hydrogen production from sodium borohydride hydrolysis in alkaline solutions. The magnetically separated nitrogen-doped carbon-supported cobalt oxide (Co x O y @NC) nanoparticles were successfully prepared by converting pyrazine-based covalent organic frameworks (COFs). The Co x O y @NC catalyst exhibited good conductivity and charge transfer ability due to its porous structure and nitrogen-rich characteristics. The H-2 generation rate reached a maximum of 2082.13 mL/min/g from NaBH4, and the catalyst also exhibited good magnetic separation capability.

Summary: This work focuses on the hydrogen production from sodium borohydride (NaBH4) hydrolysis using homogeneous copper ferrite (CuFe2O4) nanocubes. The nanocubes, produced without the use of surfactants, exhibited good catalytic activity and recyclability in the hydrolysis process. The hydrogen production rate reached up to 1.5 L/min/g at 303K, which is significantly higher than other CuFe2O4 materials. The effects of NaOH concentration, NaBH4 concentration, and reaction temperature were investigated, and the nanocubes were found to have a low activation energy of 41.53 kJ/mol.

Summary: The particle size and shape of bulk ammonia borane (NH3BH3) have received little attention in the literature. The published results on the influence of hydride dispersity on its dehydrogenation are limited and contradictory. This study presents new findings on the solid-state dehydrogenation of NH3BH3 at low temperatures. Samples with different particle characteristics, obtained by recrystallization using different procedures, were compared based on thermal analysis data and hydrogen evolution experiments. The results showed that the finely dispersed sample with a particle size of < 40μm exhibited the highest reactivity. A filamentous NH3BH3 with an ordered structure was synthesized and found to have relatively high reactivity. These findings highlight the need for further investigations on bulk ammonia borane with different particle types.

Summary: This study presents a mathematical model for the thermal decomposition of the complex compound [Ni(En)(3)](ClO4)(2) under non-isothermal conditions. The decomposition process involves the elimination of ethylenediamine, decomposition of perchlorate anions, and explosive-like oxidation of ethylenediamine. The data from dynamic mass-spectral thermal analysis and thermogravimetric analysis were modeled using a hybrid genetic algorithm, and a two-stage scheme for the thermolysis of [Ni(En)(3)](ClO4)(2) was proposed.

Summary: MnOx-ZrO2 catalysts were prepared using co-precipitation and vacuum impregnation methods and characterized through various techniques. The co-precipitated samples showed higher catalytic activity in CO oxidation compared to the vacuum impregnation samples. The results of the characterization studies revealed differences in the active components of the two preparation methods. For impregnation, the most active catalyst was obtained at 400 degrees C due to the formation of MnO2 oxide nanoparticles with Mn4+ and low-temperature reducibility. On the other hand, co-precipitation at 650-700 degrees C formed the most active CO oxidation catalysts. In this temperature range, a solid solution of MnyZr1-yO2-x and highly dispersed and active MnOx were formed.

Summary: The MnOx-ZrO2-CeO2 oxide catalysts were synthesized and their catalytic properties were studied. The Zr/Zr + Ce molar ratio had little effect on the catalytic activity, while the manganese content exhibited a volcano-like dependence in CO oxidation and a linear increase in propane oxidation. XRD and XPS analysis revealed an increase in crystalline manganese oxides and surface concentration of manganese with increasing Mn concentration in the catalyst, while the content of MnxZryCe1-x-yO2 solid solution decreased. The CO oxidation activity was determined by the balance between the solid solution and the concentration of manganese cations, while the propane oxidation activity was less sensitive to the state of manganese ion.

Summary: CO2 methanation was studied using nickel catalysts obtained by the solid-state combustion method. Complexes with different numbers of ethylenediamine molecules were chosen as precursors, and their synthesis was carried out without solvents to avoid waste liquids. The composition and structure of the complexes were confirmed by various methods. It was found that the ethylenediamine content in the complex affected the metal content in the combustion products, but the different forms of nickel did not affect the initial activation temperature of the catalysts. The sample obtained from [Ni(C2H8N2)(2)](NO3)(2) showed the highest activity in CO2 methanation.

Summary: The addition of zinc hinders the reducibility of nickel and weakens its interaction with the silica matrix, leading to the formation of solid oxide nickel-zinc solutions. Zn-modified catalysts exhibit significantly better catalytic properties in the dehydrogenation of methylcyclohexane compared to Ni-Cu counterparts. The selectivity towards toluene formation increases noticeably with a decrease in the Ni : Zn mass ratio, attributed to the promoting geometric and electronic effects from the formation of bimetallic Ni-Zn solid solutions.
