This review describes recent advances in electrochemical water electrolysis and rechargeable beyond Li-ion battery research, two emergent and widely employed technologies playing important roles in clean energy production and storage. The principle components of these electrochemical processes are electrode materials, which are currently facing cha...
Article
Production of hydrogen on-board an airplane, to feed a fuel cell secondary power generation unit, is realisable by catalytic partial dehydrogenation of kerosene. The influence of the nature support on the partial dehydrogenation of Ultra Low Sulfur Kerosene Jet A-1 using Pt-Sn based catalysts is investigated in this work. The doping of an alumina s...
Article
The partial dehydrogenation (PDh) of hydrocarbon blends may be a suitable way to produce H2 on-board of automotives or airplanes to feed fuel cells and produce electric power, avoiding storage problems. In this work very interesting data have been collected using Jet A-1 surrogate and Pt–Sn/γ-Al2O3 catalysts, operating at 450 °C and feeding the vap...
Article
The partial dehydrogenation of fuels like diesel or kerosene cuts to produce H-2 is an emerging idea of increasing interest. In the present work the study of the partial dehydrogenation of Jet A-1 fuel on Pt Sn/gamma-Al2O3 based catalysts to produce H-2 to feed an on-board (aircraft) proton exchange membrane fuel cell is presented. Extensive physic...
Article
The urea hydrolysis method allowed to prepare well-crystallized Ni–Co–Zn–Al Layered Double Hydroxides to be used as precursors of mixed oxide catalysts for the Ethanol Steam Reforming (ESR) reaction. The calcination of the layered precursors gives rise to high surface area mixed oxides, being actually a mixture of a rock salt phase (NiO), a wurtzit...
Article
Ethanol steam reforming (ESR) experiments have been performed in dilute conditions over a NiZnAl catalyst. Experiments have been performed by varying catalyst surface area, reactants flow rate, contact time, reactants feed composition and temperature. Acetic acid steam reforming experiments have also been performed. The data suggest that adsorbed a...
Article
The reactions of methanol and ethanol steam reforming (MSR and ESR) have been studied over Cu-ZnO-Al2O3 and over Ni-containing catalysts, respectively. Our spectroscopic studies, coupled with flow reactor studies, allowed us to propose mechanisms for both reactions where water takes the role of oxidant of part of the copper and nickel species. The...

IR spectroscopy of low temperature adsorbed CO and CO+NO has been used to characterize the surface species on a 5% Ni-YSZ catalyst. Dispersed surface Ni species are present on the fresh catalyst, essentially formed by Ni2+, although it is evident that these species are very easily reduced in very mild conditions to zerovalent atomic nickel. Reducti...

Article
Reactivity of pure ethanol and acetaldehyde on Ni/MgO catalyst at different reaction temperatures was investigated confirming that hydrogen production is ascribable to a series of consecutive and/or parallel reactions. FT-IR studies on adsorbed dry molecules (ethanol or acetaldehyde) showed that ethanol decomposition occurs on catalyst surface thro...
Chapter
The vibrational spectroscopies are those producing the entire (or part) vibrational spectrum of a sample, i.e. the collection of transition energies between its vibrational states. The simplest way to cause vibrational excitation is to allow the chemical species in its vibrational ground state to absorb an energy quantum from electromagnetic radiat...
Article
The conversion of the C3 organics propane, propene, isopropanol and acetone in auto-thermal and endothermic steam reforming conditions has been investigated over a Pd–Cu/Al2O3 catalyst in a flow reactor. Although several reactions may occur at lower temperatures (like dehydrogenation, oxidative dehydrogenation, dehydration and combustion), steam re...
Article
Experiments of propane and propene steam reforming have been performed over a Pd–Cu/γ-Al2O3 catalyst and over a Ni/NiAl2O4 catalyst. Over the palladium-based catalyst, the steam reforming of propene is faster and more selective than steam reforming of propane. Over the Pd catalyst, the steam reforming of propane is likely inhibited by site poisonin...

Co–H-MFI and Co–silica–alumina catalysts were comparatively characterized and their activities in CH4-SCR and NO oxidation were compared. IR measurements evidence that Co sites distribute between internal cavities and external surface of Co–H-MFI; a large fraction of protonic sites are retained. Co–silica–alumina, unlike Co–H-MFI, is inactive in CH...

In-situ UV-visible spectroscopy was used to measure the extent of reduction of active centers in VO x /γ-Al 2 O 3 during oxidative dehydrogenation (ODH) of propane. Prevalent extents of reduction (0.062 to 0.30 e -/V) are much smaller than required for the formation of stoichiometric V 3+ or V 4+ suboxides. Surface oxygen atoms are the most abundan...
