TL;DR: In this article, the authors studied correlations between the reaction rates for dehydrogenation and hydrogenation reactions and the position of the d-band center (ed) relative to the Fermi energy (EF), the ed- EF value, of various metal catalysts.
Abstract: To confirm whether the activity trends in multistep organic reactions can be understood in terms of the Hammer–Norskov d-band model in combination with the linear energy relations, we studied correlations between the reaction rates for dehydrogenation and hydrogenation reactions and the position of the d-band center (ed) relative to the Fermi energy (EF), the ed – EF value, of various metal catalysts. SiO2-supported metal (M = Ag, Cu, Pt, Ir, Pd, Rh, Ru, Ni, and Co) catalysts with the same metal loading (5 wt %) and similar metal particle size (8.9–11.7 nm) were prepared. The dehydrogenation of adsorbed 2-propanol in a flow of He and the hydrogenation of adsorbed nitrobenzene in a flow of H2 were tested as model reactions of organic reactions on the metal surface. As a test reaction of H2 dissociation on the surface, SiOH/SiOD exchange on the M/SiO2 catalysts in a flow of D2 is carried out. The liquid phase hydrogenation of nitrobenzene under 3.0 MPa of H2 is adopted as an organic reaction under realistic...

TL;DR: In this article, the performance of the prepared Fe/Cu bimetallic particles with different theoretical copper mass loadings were characterized by SEM, EDS, BET and XRD, and the effect of theoretical Cu mass loading and other operating parameters (such as initial pH, initial nitrobenzene concentration, the Fe/cu dosage and the reaction temperature) under oxic conditions (DO < 65mg/L) were investigated.

TL;DR: A sequential column experiment, containing a granular iron reducing zone and an aerobic biodegradation zone, successively degraded nitrobenzene and then aniline to below detection limits without any noticeable reduction in hydraulic conductivity from biofouling, or through the formation of precipitates.

TL;DR: The hydrophobicity of the compounds significantly affected their accumulation at the gas-liquid interface of the bubbles and it was the most important factor for the sonochemical degradation of aromatic compounds and LogP was found to be the representative parameter for understanding the hydrophobic properties of water-insoluble compounds.
