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

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

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 ...

In situ time-resolved DXAFS study of Rh nanoparticle formation mechanism in ethylene glycol at elevated temperature

Ning Yan

A combination of in situ time-resolved DXAFS and ICP-MS techniques reveals that the formation process of Rh nanoparticles (NPs) from rhodium trichloride trihydrate (RhCl3 center dot 3H(2)O) in ethylene glycol with polyvinylpyrrolidone (PVP) at elevated tem ...

A selective co-sensitization approach to increase photon conversion efficiency and electron lifetime in dye-sensitized solar cells

Michael Graetzel, Kazuteru Nonomura

Ruthenium-based C106 and organic D131 sensitizers have been judicially chosen for co-sensitization due to their complementary absorption properties and different molecular sizes. Co-sensitization yields a higher light-harvesting efficiency as well as bette ...

Adding diversity to ruthenium(II)-arene anticancer (RAPTA) compounds via click chemistry: the influence of hydrophobic chains

Paul Joseph Dyson, Anna Katherine Renfrew

The application of click chemistry to develop libraries of organometallic ruthenium-arene complexes with potential anticancer properties has been investigated. A series of ruthenium-imidazole-triazole complexes, with hydrophobic tails, were prepared from a ...

Antiproliferative activity of chelating N,O- and N,N-ruthenium(II) arene functionalised poly(propyleneimine) dendrimer scaffolds

Paul Joseph Dyson, Catherine Marie Amélie Clavel, Anna Katherine Renfrew

Chelating neutral (N,O) and cationic (N,N) first-and second-generation ruthenium(II) arene metallodendrimers based on poly(propyleneimine) dendrimer scaffolds were obtained from dinuclear arene ruthenium precursors by reactions with salicylaldimine and imi ...

Ruthenium-Catalyzed Synthesis of 1,5-Dichlorides by Sequential Intermolecular Kharasch Reactions

Rosario Scopelliti, Kay Severin, Aurélien Godinat, Katrin Anne Thommes, Charlotte Buron

Sequential intermolecular atom transfer radical addition reactions of activated dichlorides Cl2CRR′ (R = CN, CO2Et, R′ = H, CN, CO2Et) with two olefins catalyzed by [Cp*RuCl2(PPh3)] in the presence Mg allow the synthesis of linear 1,5-dichlorides. Differen ...

Wiley-Blackwell2011

Atom-transfer radical addition (ATRA) reactions of ethyl trichloroacetate, dichloromalononitrile, or diethyl 2,2-dichloromalonate with olefins followed by dechlorination have provided functionalized cyclopropanes in one step. The RuIII complex [Cp*RuCl2(PP ...

Electrochemical oxidation of ammonia (NH4+/NH3) on thermally and electrochemically prepared IrO2 electrodes

Nico de Rooij, Christos Comninellis, Olivier Frey, Agnieszka Kapalka, Stéphane Fierro, Kai Udert

The electrochemical oxidation of ammonia (NH4+/NH3) in sodium perchlorate was investigated on IrO2 electrodes prepared by two techniques: the thermal decomposition of H2IrCl6 precursor and the anodic oxidation of metallic iridium. The electrochemical behav ...

Pd, Pt, and Ru complexes of a pincer bis(amino)amide ligand

Rosario Scopelliti, Xile Hu, Oleg Vechorkin, Peng Ren, Isuf Salihu

An improved synthesis of pincer ligand bis[(2-dimethylamino)phenyl]amine (MeN2NH) was reported. Reaction of the Li complex of MeN2N with suitable Pd, Pt, and Ru precursors gave the corresponding metal complexes. The structures of the Pd, Pt, and Ru complex ...

Spectroelectrochemical studies of hole percolation on functionalised nanocrystalline TiO2 films: a comparison of two different ruthenium complexes

Mohammad Khaja Nazeeruddin, Xiong Li

We report the application of spectroelectrochemical techniques to compare the hole percolation dynamics of molecular networks of two ruthenium bipyridyl complexes adsorbed onto mesoporous, nanocrystalline TiO2 films. The percolation dynamics of the rutheni ...
