A Viable Hydrogen Storage and Release System Based on Cesium Formate and Bicarbonate Salts: Mechanistic Insights into the Hydrogen Release Step

Gabor Laurenczy, Katerina Stefania Sordakis, Andrew Francis Dalebrook

Aqueous solutions of cesium formate and bicarbonate repre- sent an effective hydrogen storage–delivery couple that under- goes either release or take up of hydrogen in the presence of {RuCl2(mTPPTS)2}2 (TPPTS = triphenylphosphine trisulfonate) and excess m ...

Competing Interactions in the Self-Assembly of NC-Ph-3-CN Molecules on Cu(111)

Harald Brune, Marina Pivetta, Giulia Elisabetta Pacchioni

We report on low-temperature scanning tunneling microscopy and spectroscopy measurements on NC-Ph-3-CN molecules adsorbed at 300 K on a Cu(111) surface. Upon cooling, the molecules form chain and honeycomb structures, incorporating Cu adatoms supplied by t ...

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 ...

Closing the pressure gap in x-ray photoelectron spectroscopy by membrane hydrogenation

Comprehensive studies of gas-solid reactions require the in-situ interaction of the gas at a pressure beyond the operating pressure of ultrahigh vacuum (UHV) X-ray photoelectron spectroscopy (XPS). The recent progress of near ambient pressure XPS allows to ...

Round-the-clock power supply and a sustainable economy via synergistic integration of solar thermal power and hydrogen processes

François Maréchal, Rakesh Agrawal

We introduce a paradigm-"hydricity"-that involves the coproduction of hydrogen and electricity from solar thermal energy and their judicious use to enable a sustainable economy. We identify and implement synergistic integrations while improving each of the ...

Triphenyltin(IV) adducts of diphosphoryl ligands: structural, electronic and energy aspects from X-ray crystallography and theoretical calculations

Kurt Schenk

Some triphenyltin(IV) adducts with a family of diphosphoryl ligands, RR'P(O)-X-P(O)RR' (R = OPh, Ph, R' = R, An (aniline)) and X = 1,4-OC6H4O, 1,4-OC6H4NH, 1,4-NHC6H4NH 1,4-(NHCH2)(2)C6H4, 1,3-(NHCH2)(2)C6H4 and piperazine have been synthesized and charact ...

Visualization of electronic density

The spatial volume occupied by an atom depends on its electronic density. Although this density can only be evaluated exactly for hydrogen-like atoms, there are many excellent algorithms and packages to calculate it numerically for other materials. Three-d ...
