Model cobalt catalysts for CO2 hydrogenation were prepared using colloidal chemistry. The turnover frequency at 6 bar and at 200–300 °C increased with cobalt nanoparticle size from 3 to 10 nm. It was demonstrated that near monodisperse nanoparticles...

C–C coupling reactions are ubiquitous in synthetic chemistry, joining together fragments of larger molecules within overall synthetic schemes. Many obvious operational advantages would result from catalyzing such processes heterogeneously, however, t...
