Adsorption and diffusion of hydrogen on Pd(211) and Pd(111): Results from first-principles electronic structure calculations

We have carried out first-principles calculations of H adsorption on Pd 211 using density-functional theory with the generalized gradient approximation in the plane-wave basis to find out that the most preferred is the threefold hollow site on the terrace of Pd 211 with an adsorption energy of 0.52 eV: the hcp and fcc sites being almost energetically equally favorable. For subsurface H adsorpti...

Direct Synthesis of Low-Coordinate Pd Catalysts Supported on SiO2 via Surface Organometallic Chemistry

Highly dispersed low-coordinate Pd sites on SiO2 are fabricated by grafting the Pd II PCP-pincer complex (PCP)Pd−OH (PCP = 2,6-C6H3(CH2PBu2)2) on SiO2, followed by calcination with ozone (100 °C) and reduction with H2 (300 °C). The chemisorption process and structure of this organometallic complex on SiO2 is established by solutionphase H and P NMR and solid-state P CPMAS NMR spectroscopy, XPS,...

Pd and Fe3O4 Nanoparticles Supported on ‎N-(2-Aminoethyl)Acetamide Functionalized ‎Cellulose as an Efficient Catalyst for ‎Epoxidation of Styrene

A new efficient heterogeneous catalyst was introduced for the epoxidation of styrene. The catalyst was obtained from functionalization of cellulose with N-(2-aminoethyl)acetamide, and then deposition of nanoparticles and Pd(0) nanoparticles on the modified cellulose. The Fe3O4 nanoparticles were deposited via chemical oxidation in basic media and Pd(0) nanoparticles we...

Catalytic Investigation of Aluminum Effects on Benzene Hydrogenation Selectivity over Nickel Supported HMS/HZSM-5 Composites

Ni/Al-HMS/HZSM-5 catalysts with varying amounts of Si/Al ratios were prepared via the impregnation method and evaluated for the hydrogenation of benzene at 130−190 °C. To study the catalyst characterization, various methods were used as X-ray diffraction, X-ray fluorescence, Fourier transform infrared spectroscopy, ultraviolet-visible diffuse reflectance spectroscopy, temperature-programmed des...
