Efficient and selective carbon dioxide reduction on low cost protected Cu2O photocathodes using a molecular catalyst

Michael Graetzel, Mohammad Khaja Nazeeruddin, Peng Gao, Jingshan Luo, Thomas Moehl, Matthew Thomas Mayer, Stanley David Tilley, Marcel Roland Schreier

Photoelectrochemical reduction of CO2 to CO was driven by a TiO2-protected Cu2O photocathode paired with a rhenium bipyridyl catalyst. Efficient and selective CO evolution was shown to be stable over several hours. The use of protic solution additives to o ...

A comparison of strategies for estimation of ultrafine particle number concentrations in urban air pollution monitoring networks

Matteo Reggente, Prashant Kumar

We propose three estimation strategies (local, remote and mixed) for ultrafine particles (UFP) at three sites in an urban air pollution monitoring network. Estimates are obtained through Gaussian process regression based on concentrations of gaseous pollut ...

Iridium(I)/N-Heterocyclic Carbene Hybrid Materials: Surface Stabilization of Low-Valent Iridium Species for High Catalytic Hydrogenation Performance

David Lyndon Emsley, David Benjamin Roger Antoine Gajan

An Ir-I(NHC)-based hybrid material was prepared using a methodology which allowed the precise positioning and isolation of the Ir centers along the pore channels of a silica framework. The full characterization of the material by solid-state NMR spectrosco ...

Uncapped Au-Pd colloidal nanoparticles show catalysis enhancement

Giorgio Margaritondo, Ying Chen

The catalytic properties of Pd trigger a strong interest on the related catalysis by Au-Pd nanoparticles. However, the analysis of such phenomena was complicated so far by the presence of capping. Using x-ray irradiation, we could produce uncapped Au-Pd na ...

Increasing Pt selectivity to vinylaniline by alloying with Zn via reactive metal-support interaction

Lioubov Kiwi, Charline Berguerand, Artur Yarulin

The promoting effect of Zn on Pt-based catalyst was studied for the liquid-phase hydrogenation of 3-nitrostyrene (3-NS). The monodispersed Pt nanoparticles (ca. 2.3 nm) supported on ZnO catalyzed the target 3-vinylaniline (3-VA) formation (S3-VA = 97% at X ...

Catalytic Applications and Mechanistic Investigations of Iron Bis(oxazolinylphenyl)amino Pincer Complexes in Kumada Cross Coupling and Hydrosilylation Reactions

Gerald Bauer

The aim of the project was to investigate iron bis(oxazolinylphenyl)amino (bopa) pincer complexes as pre-catalysts in the enantioselective Kumada cross-coupling of non-activated alkyl halides with aryl Grignard reagents. From this preliminary cross-couplin ...

Evidence from in Situ X-ray Absorption Spectroscopy for the Involvement of Terminal Disulfide in the Reduction of Protons by an Amorphous Molybdenum Sulfide Electrocatalyst

Xile Hu, Heron Vrubel, Daniel Andreas Merki

The reduction of protons into dihydrogen is important because of its potential use in a wide range of energy applications. The preparation of efficient and cheap catalysts for this reaction is one of the issues that need to be tackled to allow the widespre ...

Stereoselective Synthesis of Trisubstituted Alkenes through Sequential Iron-Catalyzed Reductive anti-Carbozincation of Terminal Alkynes and Base-Metal-Catalyzed Negishi CrossCoupling

Xile Hu, Chi Wai Cheung

The stereoselective synthesis of trisubstituted alkenes is challenging. Here, we show that an iron-catalyzed anti-selective carbozincation of terminal alkynes can be combined with a base-metal-catalyzed cross coupling to prepare trisubstituted alkenes in a ...
