Bel The dehydrogenation of ethane to ethene on Sn-promoted Pt supported on calcined hydrotalcite, PtSn/ Mg(Al)O, was investigated with the aim of understanding the effects of Sn on the local environment of the dispersed Pt, ...

The evaluation of texture as a function of recrystallization has been characterized for directly cold rolled Al-6Mg, Al-6Mg-0.4Sc and Al-6Mg-0.4Sc-0.2Zr alloys. Samples were annealed isothermally at 400 °C for 1 to 240 minutes to allow recrystallization. Recrystallization kinetics of the alloys is analyzed from the micro-hardness variation. Isothermally annealed samples of aluminum alloys were ...

The precursors of Mg-Al hydrotalcite (Mg/Al-LDHs-NO3) were prepared by low saturation coprecipitation method (constant pH method). In addition, alsine-intercalated magnesium-aluminum (LDHs-Ala) was synthesized pH) and nucleation/crystallization isolation methods when the value higher than isoelectric point alanine. release properties alanine intercalated hydrotalc in simulated gastric fluid (hy...

Two different hydrotalcite-like compounds were prepared and used as substrates for the electrochemical removal of extremely toxic pollutant cations, such as Cd(ii) and Pb(ii), from aqueous solutions, and their subsequent recovery for further potential applications. By deposition on the hydrotalcite electrode, it was possible to remove 75% of Cd(ii) contained in a starting 5.2 mM solution of CdC...

Bel A novel approach is described for preparing Ga-promoted Pt particles for the dehydrogenation of light alkanes to alkenes. The modifying element, Ga, was introduced by transference from the support, a calcined Mg(Ga)(Al)O...
