Journal ArticleDOI

TL;DR: The data and their theoretical and mechanistic interpretations indicate that the remarkable structure insensitivity observed for CO oxidation reactions reflects average CO binding properties that are essentially independent of cluster size.
Journal ArticleDOI
Specificity of Sites within Eight-Membered Ring Zeolite Channels for Carbonylation of Methyls to Acetyls
TL;DR: Such specificity of methyl reactivity upon confinement within small channels appears to be unprecedented in catalysis by microporous solids, which typically select reactions by size exclusion of bulkier transition states.
Journal ArticleDOI
The combination of deconvolution and density functional theory for the mid-infrared vibrational spectra of stable and unstable rhodium carbonyl clusters
TL;DR: In this article, the density functional theory methods with the B3LYP, PBE and B3PW91 functionals in conjunction with the LanL2DZ and DGDZVP basis sets were used for spectral prediction of reactive rhodium carbonyl systems.
Journal ArticleDOI
The Development of Continuous Process for Alkene Ozonolysis Based on Combined in Situ FTIR, Calorimetry, and Computational Chemistry
TL;DR: In this paper, two continuous apparatuses were designed that are capable of safely scaling the highly energetic ozonolysis reaction to multikilogram scale where flow chemistry allowed excellent temperature control and minimized the inventory of the highly unstable ozonide intermediate.
Journal ArticleDOI
Chemical and kinetic study of acetophenone hydrogenation over Pt/Al2O3: Application of BTEM and other multivariate techniques to quantitative on-line FTIR measurements
TL;DR: In this article, the authors performed a semi-batch heterogeneous catalytic hydrogenation of acetophenone (Aceph) over Pt/Al2O3 in d8d8-toluene/h8h8-toene at 273 K using on-line quantitative Fourier transform infrared (FTIR) spectroscopy measurements.
