With increasing emphasis placed on cleaner chemical synthesis, energy efficiency and waste minimisation, the manufacture of pharmaceuticals and fine chemicals is undergoing a progressive shift from conventional stoichiometric organic processes to a harness ...
The hydrogen sorption pathways of alkali alanates were analyzed and a mechanism for the catalytic hydrogen sorption was developed. Gibbs free energy values of selected intermediate steps were calculated based on experimentally determined thermodynamic data ...
A major challenge in the face of increasing global energy demand is the development of alternative environmentally friendly and renewable energy resources. Hydrogen is an excellent energy carrier, but has drawbacks in storage density and is dangerous to ha ...
Reaction of α-substituted α-isocyanoacetates with phenyl vinyl selenones in the presence of a catalytic amount of base (DBU or Et3N, 0.05− 0.1 equiv) followed by addition of p-toluenesulfonic acid (PTSA, 0.1−0.2 equiv) afforded 4,4,5-trisubstituted 1,3-oxa ...
The limited fossil fuel resources and the increasing levels of greenhouse gases in the atmosphere are the driving forces in the research of alternative ways of energy production and storage. The use of solar energy is expected to grow as our society claims ...
Hydrogenases are biological catalysts for hydrogen evolution and activation. While many model complexes of hydrogenases can catalyze the hydrogen evolution reaction, few of them can react with hydrogen. Here we review the hydrogen-activating models of hydr ...
We demonstrate that the kinetics of the Sabatier reaction catalysed by sorption catalysts depends on the nanostructure of the catalyst-sorbent system. The catalysts are prepared by ion exchange of a nickel nitrate solution in two zeolites with different po ...
For different hydrogenated metal intercalated fullerides (Na10C60-H, Li12C60-H, and Li28C60-H) the activation energies for hydrogen desorption were determined by DSC. The Vyazovkin advanced method (VA) was used for the calculation of the reaction model fre ...
The selective dehydrogenation of aqueous solutions of HCOOH/HCOONa to H2 and CO2 gas mixtures has been investigated using RuCl3·3H2O as a homogeneous catalyst precursor in the presence of di␣erent monoaryl-biaryl or alkyl-biaryl phosphines and aryl diphosp ...
