Size and Shape-controlled Pd Nanocrystals on ZnO and SiO2: When the Nature of the Support Determines the Active Phase

Lioubov Kiwi, Rocio Micaela Crespo Quesada

The structure sensitivity of acetylene hydrogenation was studied over size-controlled cubic and octahedral Pd nanocrystals (NCs) supported on ZnO and SiO2. Acetylene hydrogenation was found to be structure sensitive [with Pd(111) in octahedra being more ac ...

A toolbox of oligopeptide-modified polymers for tailored elastomers

Véronique Michaud, Holger Frauenrath, Joël Cugnoni, Marijana Mionic Ebersold, Ruben Anton Snellings, Emmanuel Croisier, Su Liang, Thomas Schweizer

Biomaterials are constructed from limited sets of building blocks but exhibit extraordinary and versatile properties, because hierarchical structure formation lets them employ identical supramolecular motifs for different purposes. Here we exert a similar ...

A quasi core-shell nitrogen-doped graphene/cobalt sulfide conductive catalyst for highly efficient dye-sensitized solar cells

Michael Graetzel

A novel conductive catalyst was designed based on a quasi core shell structure of N-doped graphene/cobalt sulfide. This platinum-free catalyst shows high catalytic activity and conductivity owing to close interactions between the core (cobalt sulphide) and ...

One-pot photoinduced synthesis of conductive polythiophene-epoxy network films

Federica Sordo, Marco Sangermano

In this paper, we describe a novel methodology for fabricating conductive epoxy-polythiophene network films by simultaneous photoinduced step-growth and cationic ring opening polymerization processes. For this purpose, formulations containing a bifunctiona ...

Photocatalytic degradation of Remazol Brilliant Blue (R) by sol-gel derived carbon-doped TiO2

Ravindranathan Thampi, Michael Jon Mattle

A simple, cheap and reproducible method to produce a C-doped TiO2 photocatalyst is presented, which can harvest visible light. This doped catalyst is able to degrade a stable organic dye molecule, Remazol Brilliant Blue (R) (RBB), under sunlight and visibl ...

RhCl3-Mediated Coupling Reactions of tert-Butyl Acetylene

Rosario Scopelliti, Kay Severin, Euro Solari, Gregor Kiefer, Barnali Dutta

RhCl3 is shown to mediate unusual coupling reactions of tert-butyl acetylene. When RhCl3(H2O)n was heated with four equivalents of tert-butyl acetylene in methanol, the dinuclear complex [{Rh(μ-Cl)(CH2tBu)(tBuC=CHCOCH2tBu)}2] (2) was isolated. A larger exc ...

Metal complexes for use as dopants and other uses

Michael Graetzel, Mohammad Khaja Nazeeruddin, Julian Burschka

The invention relates to electrochemical devices comprising complexes of cobalt comprising at least one ligand with a 5- or six membered, N- containing heteroring. The complex are useful as p- and n- dopants, as over of electrochemical devices, in particul ...

Carbon-Doped TiO2 and Carbon, Tungsten-Codoped TiO2 through Sol-Gel Processes in the Presence of Melamine Borate: Reflections through Photocatalysis

Ravindranathan Thampi, Michael Jon Mattle

A series of C-doped, W-doped, and C,W-codoped TiO2 samples have been prepared using modified sol-gel techniques. Reproducible inexpensive C-doping arises from the presence of melamine borate in a sol-gel mixture, whereas W-doping is from the addition of tu ...

Electrophilic alkynylation: the dark side of acetylene chemistry

Jérôme Waser, Jonathan Brand

In addition to the well-established nucleophilic alkynylation, the use of electrophilic alkynes can expand tremendously the scope of acetylene transfer reactions. The use of metal catalysis has recently led to a rebirth of this research area. Halogenoalkyn ...
