Z-scheme Photocatalytic CO2 Conversion on Three-Dimensional BiVO4/Carbon-Coated Cu2O Nanowire Arrays under Visible Light 10.1021/acscatal.8b00003 2018-04-12 Cuprous oxide (Cu2O) is one of the most promising materials for photoreduction of CO2 because of its high conduction band and small band gap, which enable the production of high-potential electrons under visible-light irradiation. However, it is difficult to ...
Fabricating a Au@TiO2 Plasmonic System To Elucidate Alkali-Induced Enhancement of Photocatalytic H2 Evolution: Surface Potential Shift or Methanol Oxidation Acceleration? 10.1021/acscatal.8b00317 2018-04-12 Enhancement in photocatalytic H2 evolution induced by an alkaline reaction environment has been experimentally recognized, but there is not yet a consensus regarding the promotion mechanism (surface potential shift (SPS) or methanol oxidation (MO)). Herein, w...
Chirality, Rigidity, and Conjugation: A First-Principles Study of the Key Molecular Aspects of Lignin Depolymerization on Ni-Based Catalysts 10.1021/acscatal.8b00067 2018-04-12 Efficient lignin depolymerization is crucial for achieving a positive economical return in biorefineries. However, because of the complex cross-polymerized network formed by the aromatic lignols, catalysts that can work at low temperatures perform insufficien...
Chain Transfer with Dialkyl Zinc During Hafnium–Pyridyl Amido-Catalyzed Polymerization of 1-Octene: Relative Rates, Reversibility, and Kinetic Models 10.1021/acscatal.8b00524 2018-04-12 Kinetic modeling is applied to the polymerization of 1-octene catalyzed by Hf–pyridyl amido complex 1/[CPh3][B(C6F5)4] in the presence of chain-transfer agent ZnEt2. The model reproduces monomer consumption, end group data, and the bimodal MWD (molecular weig...
Rh(III)-Catalyzed Mild Coupling of Nitrones and Azomethine Imines with Alkylidenecyclopropanes via C–H Activation: Facile Access to Bridged Cycles 10.1021/acscatal.8b00746 2018-04-12 Bridged cycles are an important class of structural motif in various biologically active molecules. Rh(III)-catalyzed C–H activation of nitrones and azomethine imines in the context of dipolar addition with alkylidenecyclopropanes (ACPs) have been realized. B...
Nanolayered Cobalt-Molybdenum Sulfides as Highly Chemo- and Regioselective Catalysts for the Hydrogenation of Quinoline Derivatives 10.1021/acscatal.7b04260 2018-04-11 Herein, a general protocol for the preparation of a broad range of valuable N-heterocyclic products by hydrogenation of quinolines and related N-heteroarenes is described. Interestingly, the catalytic hydrogenation of the N-heteroarene ring is chemoselectivel...
