From Colloidal Monodisperse Nickel Nanoparticles to Well-Defined Ni/AlO Model Catalysts.

In the past few decades, advances in colloidal nanoparticle synthesis have created new possibilities for the preparation of supported model catalysts. However, effective removal of surfactants is a prerequisite to evaluate the catalytic properties of these catalysts in any reaction of interest. Here we report on the colloidal preparation of surfactant-free Ni/AlO model catalysts.
