Hydrogenation quasi-homogeneous

Solutions of Moiseev s giant Pd colloids [49,161-166] were shown to catalyze a number of reactions in the quasi homogeneous phase, namely oxidative ace-toxylation reactions [162], the oxidative carbonylation of phenol to diphenyl carbonate [166], the hydrogen-transfer reduction of multiple bonds by formic acid [387], the... 

Clusters, as possible catalytic reactors, are perfectly dispersed in solutions. They are thus suitable systems for observing, under quasi-homogeneous conditions by time-resolved techniques, the kinetics of catalyzed electron transfer, which would be inaccessible on a solid catalyst. It was demonstrated that the reaction of radiation-induced free radicals COT and (CH3)2COH catalyzed by metal clusters started by the storage of electrons on clusters as charge pools and that electrons were then transferred pairwise to water-producing molecular hydrogen [22,75]. 

Feynman and was first introduced in the context of QMC by Lee et al. Later Ceperley and coworkers extended the backflow idea to the homogeneous electron gas and the inhomogeneous systems liquid and solid hydrogen. Lopez Rios et al. extended this approach further to atoms and molecules and were able to demonstrate the possibility to reduce the node location error with optimized quasi-coordinates. In the case of the carbon dimer C2 these authors could improve the correlation energy from 92% to 95% of the exact value when switching from real to...
