Formic acid, a major product of biomass processing, is regarded as a potential liquid carrier for hydrogen storage and delivery. The catalytic dehydrogenation of FA to generate hydrogen using heterogeneous catalysts is o...

The mechanical alloys-composite MАs (Mg +10 % wt.Ti + 5 % wt.Y and Mg +10 % wt.Ni + 5 % wt.Y) were synthesized. The phase content, microstructure, the thermal stability, kinetics of hydrogen desorption from the MgH2 hyd...

Lead–acid batteries are robust, low-cost, and have a large power-to-weight ratio. Recently, small amounts of carbon-based materials with a high surface area have been included in the Pb electrode as additives to improv...

Hydrolysis is an effective method for generating hydrogen from Mg alloy waste provided from the sacrificial anode industry. Mg alloy was ball milled under H2 to enhance its hydrolysis reactivity. The effect of ball milli...

Fuel Cell Recreational Vehicles (FCRVs) are emerging as a promising sustainable alternative to conventional diesel- and gasoline-powered recreational vehicles. This paper evaluates the financial and technological aspects...

Today’s main topic is global warming and carbon neutrality. We therefore investigate biofuel (Bio-Energy) in our living space; its amount is comparable to fossil fuel. We analyze the production of hydrogen by processin...

The first NHC–Cu-catalyzed decomposition of formic acid (FA) is reported. In the presence of PhSiH3, only hydrogen is generated while CO2 is captured by a silane species. The decomposition of an equimolar mixture of FA...

The existent research literature of Dye Sensitized Solar Cells (DSSC) is mainly focused on the dye but there are very few studies focused in the semiconductor. Here, we present the performance of hydrogen titanate nanotu...

Ferryl compounds [Fe(IV)=O] in living organisms play an essential role in the radical catalytic cycle and degradation processes of hemeproteins.We studied the reactions between H2O2 and hemoglobin II (HbII) (GlnE7, TyrB1...

As the global carbon crisis worsens, we need the technology which can evolve from capturing carbon to efficiently using it. Dielectric barrier discharge (DBD) systems under mild conditions, a type of non-thermal plasma (...

Climate change is a touchable phenomenon and hydrogen has become an attractive solution for experts and for policymakers. However, in order to understand the environmental impact of an energy vector, it is necessary to c...

Abstract Herein, Ru⁰/TiO₂ nanocomposites containing 0.5 wt% Ru were prepared via a simple wet-impregnation route followed by chemical reduction and were thoroughly characterized by XRD, FTIR, SEM, TEM, and EDS analys...

In this work we identify the limiting mechanism in the hydrogen absorption reaction of LaNi(5-x)Sn(x) alloys. For this purpose the absorption reaction was modelled as a process involving several partial reactions occurri...

Abstract Intact spinach chloroplasts scavenge hydrogen peroxide with a peroxidase that uses a photoreductant as the electron donor, but the activity of ruptured chloroplasts is very low [Nakano and Asada (1980) Plant &am...

In this article, we address the design of hydrogen supply chains for vehicle use with economic and environmental concerns. Given a set of available technologies to produce, store, and deliver hydrogen, the problem consis...

Rising concerns over carbon emissions from fossil fuels have fueled interest in renewable energies. Hydrogen, as a clean energy source, stands out for its free of pollution and high calorific value. However, challenges i...

The 1-heptyne selective hydrogenation carried out at 150kPa, and at 283 and 303K using Ru/Al2O3 and Ru/C as catalysts, was studied. Catalysts were prepared by the incipient wetness impregnation technique using RuCl3 as p...

Blending hydrogen into natural gas pipelines offers a promising solution for large-scale hydrogen transportation. The thermophysical parameters of hydrogen-blended natural gas (HBNG), particularly the Joule-Thomson (J-T)...

Pulsed laser deposition (PLD), as an advanced synthesis technology with unparalleled control over thin films, has evolved into a universal platform for optoelectronic materials engineering. Its unique advantages includin...

The high population growth rate, the accelerated industrialization and unpredictability of oil prices in the world have considerably raised the energy demand which has enhanced the necessity of alternative and sustainabl...

Hydrogen technology is significantly influencing the transformation of the energy sector, supported by recent advancements in global infrastructure. The production of sustainable hydrogen is contingent upon the developme...
