platinumCluster Compounds The atomicity of subnanometer platinum clusters significantly influences their catalytic activity. In their Communication on page 9810 ff., K. Yamamoto et al. report Pt19 as the most catalytically active species for oxygen reduction.doi:10.1002/anie.201583461...
oxygenreductionreactionplatinumOn a subnanometer scale, an only one-atom difference in a metal cluster may cause significant transitions in the catalytic activity due to the electronic and geometric configurations. We now report the atomicity-specific catalytic activity of platinum clusters with ...
An attempt is made to analyse the temperature dependence of relative polyatomicity, utilizing an acoustic approach, in terms of density and shear viscosity, in liquid argon, nitrogen, oxygen, methane and hydrogen. Liquid hydrogen exhibits the greatest sensitivity to temperature change while liquid ...
