Hydrazine borane N2H4BH3 (HB, 15.4 wt% H) is a promising chemical hydrogen storage material. Herein, we report high-extent dehydrogenation of HB (i.e.hydrolysis the group BH3 and decomposition moiety N2H4) in presence nickel–platinum nanoparticles (NPs) at 50 °C. Using Ni0.89Pt0.11 NPs, 5.79 ± 0.05 equiv. H2 + N2 per can be released, corresponding to selectivity as high 93 1%.
Methanolysis of sodium borohydride (NaBH4) is a way recovering the hydrogen stored in hydride. Though reaction spontaneous, it can be accelerated by virtue Co-TiO2 or Ru-TiO2 catalysts. Under our experimental conditions, shows high catalytic performances, higher than those Ru-TiO2. Hydrogen generation rates 144 to 644 L(H2) min−1 g−1(Co) were measured as Co content was decreased. The kinetic parameters catalyzed determined. Co-TiO2-catalyzed methanolysis follows power law, i.e. r20 =...
Abstract The photocatalytic properties of TiO 2 modified by chromium are usually found to depend strongly on the preparation method. To clarify this problem, two series chromium‐doped titania with a content up 1.56 wt % have been prepared under hydrothermal conditions: first (Cr:TiO ) is intended dope bulk , whereas second (Cr/TiO load surface Cr. catalytic compared in oxidation formic acid. Characterization data provides evidence that Cr/TiO catalysts located as amorphous CrOOH clusters. In...
To produce ultra low-sulfur gasoline and meet the new regulations, improvement of HDS reaction by removal inhibitors, like nitrogen-containing compounds (N-compounds) commonly found in middle distillates used for diesel feed, could be worth considering. Liquid–liquid extraction using 1-butyl-3-methyl-imidazolium chloride (BMIm+Cl−) was to a very promising approach neutral N-compounds with high selectivity towards sulfur. BMIm+Cl− first evaluated synthetic solution dibenzothiophene carbazole...
A new simple method is described, allowing introduction of nitrogen into the TiO2 lattice at low temperatures. The technique based on oxophilic molecules, such as CCl4, reaction mixture. treatment titanium dioxide powders by NH3–CCl4 mixtures leads to highly dispersed N-doped TiO2. As compared bare or same oxide treated with sole NH3, solids showed a stronger red shift in optical absorption and enhanced photocatalytic activity under visible light, demonstrated for two reactions formic acid...
In this work, the origin of Raman defects band at 570 cm−1 praseodymium-doped ceria was revisited from in situ spectra using six different exciting lines between 458 and 785 nm low temperatures after oxidizing or reducing treatment. The observation overtones fast change relative intensity with excitation wavelength were explained by a resonance effect around 514 nm, which involved Pr4+ containing defect stabilized oxidized state leading to an absorption 530 nm. reduction cations contained...
Hydrothermal liquefaction (HTL) is a promising process for the energetic valorization of low-value feedstocks. However, HTL crude oils are incompatible with existing fuel standards, making their upgrade imperative. Nonetheless, hydrotreatment (HDT) still challenge due to complex nature feedstock. Therefore, this work explores relationship between oil origin and HDT conversion. Five from different feedstocks, namely, oak sawdust, Brewer's Spent Grain (spent grain), sewage sludge two origins,...
