TL;DR: The obtained enthalpy value indicates that the chelation of copper ions among the aminated polyacrylonitrile can be regarded as a chemical adsorption process and fit well with the Langmuir isotherm.

TL;DR: In this article, the spin-polarized gradient-corrected density-functional theory was used to study the adsorption of atomic H on Ni (111), (100) and (110) surfaces.

TL;DR: In this article, the kinetics of CO2reforming of CH4 were studied over Pt supported on TiO2, ZrO2 and Cr2O3, and the catalysts were characterized using chemisorption, X-ray diffraction, diffuse reflectance infrared Fourier transform spectroscopy (DRIFTS), temperature-programmed hydrogenation (TPH), and temperatureprogrammed surface reaction.

TL;DR: In this paper, the stable surface species formed from the chemisorption of acetylene (C2H2) or ethylene (c2H4) on the Pt(111) surface (T∼300-350 K) has been studied by a low-energy electron diffraction intensity analysis.
Abstract: The stable surface species formed from the chemisorption of acetylene (C2H2) or ethylene (C2H4) on the Pt(111) surface (T∼300–350 K) has been studied by a low‐energy electron diffraction intensity analysis. High resolution electron energy loss spectra reported by Ibach et al. have been interpreted by comparison to infrared data on relevant model compounds. The surface species most consistent with these studies is ethylidyne ( C–CH3). The species is coordinated to a threefold surface site with the C–C axis normal to the surface within an uncertainty of ∼15°. A saturated C–C bond length of 1.50±0.05 A and three equivalent Pt–C bond lengths of 2.00±0.05 A are determined by the LEED analysis and are consistent with the reported structures of ethylidyne in organometallic clusters. The ethylidyne group forms readily upon exposure of C2H4 to the Pt(111) surface at T∼300 K with the loss of one hydrogen atom per ethylene. The complete conversion of C2H2 to ethylidyne requires the presence of hydrogen atoms and pro...
