A conceptual translation of homogeneous catalysis into heterogeneous catalysis: homogeneous-like heterogeneous gold nanoparticle catalyst induced by ceria supporter.
Translation of homogeneous catalysis into heterogeneous catalysis is a promising solution to green and sustainable development in chemical industry. For this purpose, noble metal nanoparticles represent a new frontier in catalytic transformations. Many challenges remain for researchers to transform noble metal nanoparticles of heterogeneous catalytic active sites into ionic species of homogeneo...
متن کاملHeterogeneous asymmetric catalysis*
Examples of enantioselective catalysts, including homogeneous supported catalysts and biphasic liquid/liquid, are described and compared. In the case of asymmetric hydride transfer, polythiourea was proven to be more efficient for ruthenium-catalyzed reduction of aryl ketones, although the iridium complexes gave rise to higher ee when using amino sulfonamide bound to a polystyrene matrix. In th...
متن کاملCatalysis by Supported Gold Nanoclusters
The physical and chemical properties of supported Au clusters are markedly sensitive to cluster size and morphology. To investigate the origin of the unique properties of nanosized Au clusters, model catalysts consisting of Au clusters of varying sizes have been prepared on single crystal TiO2(110) and ultrathin films of single crystalline TiO2, SiO2, and Al2O3. The morphology, electronic struc...
متن کاملGold catalysis for organic synthesis
The past decade has witnessed a remarkable growth in the number of organic reactions that are catalyzed by homogeneous gold complexes. Many of the early reported reactions took advantage of the propensity of gold complexes to serve as excellent catalysts for reactions that proceed through π-activation of carbon–carbon multiple bonds. Subsequently, the reactivity paradigms available for gold com...
متن کاملNoncovalent Bonding Controls Selectivity in Heterogeneous Catalysis: Coupling Reactions on Gold.
Enhancing the selectivity of catalytic processes has potential for substantially increasing the sustainability of chemical production. Herein, we establish relationships between reaction selectivity and molecular structure for a homologous series of key intermediates for oxidative coupling of alcohols on gold using a combination of experiment and theory. We establish a scale of binding for mole...
