The effect of supported MoOX structures on the reaction pathways of propene formation in the metathesis of ethylene and 2-butene
2014, Hahn, T., Kondratenko, E.V., Linke, D.
The kind of surface MoOX structures on Al2O3–SiO2 was found to determine propene selectivity in the metathesis of ethylene and 2-butene. Compared to isolated tetrahedral MoOX species, their polymerized octahedral counterparts show significantly lower activity for isomerisation of 2- to 1-butene thus hindering non-selective metathesis of these butenes. In addition, they reveal higher ability to engage ethylene in propene formation.
A crystalline anionic complex of scandium nitride endometallofullerene: Experimental observation of single-bonded (Sc3N@Ih-C80−)2 dimers
2016, Konarev, Dmitri V., Zorina, Leokadiya V., Khasanov, Salavat S., Popov, Alexey A., Otsuka, Akihiro, Yamochi, Hideki, Saito, Gunzi, Lyubovskaya, Rimma N.
Reduction of scandium nitride clusterfullerene, Sc3N@Ih-C80, by sodium fluorenone ketyl in the presence of cryptand[2,2,2] allows the crystallization of the {cryptand[2,2,2](Na+)}2(Sc3N@Ih-C80−)2·2.5C6H4Cl2 (1) salt. The Sc3N@Ih-C80˙− radical anions are dimerized to form single-bonded (Sc3N@Ih-C80−)2 dimers.
Single molecule level plasmonic catalysis – a dilution study of p-nitrothiophenol on gold dimers
2015, Zhang, Zhenglong, Deckert-Gaudig, Tanja, Singh, Pushkar, Deckert, Volker
Surface plasmons on isolated gold dimers can initiate intermolecular reactions of adsorbed p-nitrothiophenol. At the single molecule level when dimerization is not possible an intramolecular reaction can be observed. Experimental evidence indicates that plasmon-induced hot electrons provide the required activation energy.
