Hydrogen Storage in the Carbon Dioxide - Formic Acid Cycle

Gabor Laurenczy, Mickael Montandon-Clerc, Cornel Fink

This year Mankind will release about 39 Gt carbon dioxide into the earth's atmosphere, where it acts as a greenhouse gas. The chemical transformation of carbon dioxide into useful products becomes increasingly important, as the CO2 concentration in the atm ...

Mechanistic Study on the Palladium(II)-Catalyzed Synthesis of 2,3-Disubstituted Indoles Under Aerobic Conditions: Anion Effects and the Development of a Low-Catalyst-Loading Process

Qian Wang, Bo Yao, Jieping Zhu

As a result of detailed mechanistic and kinetic studies, we have proposed that PdX2-catalyzed oxidative coupling of o-alkynylanilines 1 with terminal alkynes 2 under aerobic conditions is initiated by aminopalladation of 1 followed by ligand exchange of th ...

Diaminophosphine Oxide Ligand Enabled Asymmetric Nickel-Catalyzed Hydrocarbamoylations of Alkenes

Nicolai Cramer, Pavel Alexandrovich Donets

Chiral trivalent phosphorus species are the dominant class of ligands and the key controlling element in asymmetric homogeneous transition-metal catalysis. Here, novel chiral diaminophosphine oxide ligands are described. The arising catalyst system with ni ...

Fe, Co, and Ni Ions Promote the Catalytic Activity of Amorphous Molybdenum Sulfide Films for Hydrogen Evolution

Stéphane Fierro, Lorenzo Rovelli, Xile Hu, Heron Vrubel, Daniel Andreas Merki

Molybdenum sulfide materials had been shown as promising non-precious catalysts for hydrogen evolution. This paper describes the study of the promotional effect of certain transition metal ions on the activity of amorphous MoS3 films. Ternary metal sulfide ...

Propene oligomerization over Ni-exchanged Na-X zeolites

Guillaume Bastien Baur

The oligomerization of propene was investigated over a series of nickel ion-exchanged Na-X zeolites with varying Ni loadings. Catalyst characterization by temperature-programmed reduction, elemental analysis, and XANES indicates that all of the exchanged N ...
