The interaction of NH3 with different Fe clusters and nanoparticles was evaluated using a periodic density functional theory method. The preferred adsorption sites, adsorption energies of NH3, the transition states and the ...

This work analyzes the deposition conditions of thin layers of γ-Al2O3 by dip-coating on a spherical substrate of α-Al2O3 spheres. Results showed that under controlled deposition conditions, a structured support of α-Al2O3 ...

In this work, the modifying effect of alkaline metals (Li, Na and K) is studied on the acid properties of the support and on the behavior of PtSn/γ-Al2O3 catalytic systems, in the isobutane dehydrogenation. The isopropyl ...

Small metallic clusters -mediated gas phase catalysis studies give lights to understand simple and complex catalytic processes, and help in the discovery and explanation of non-traditional “molecular-scale” catalytic ...
