Nickel formate serves as an ideal catalyst precursor for surface-bound thermal and plasma-enhanced CVD growth of carbon nanotubes. As the method of deposition of the Ni catalyst is solution-based, it benefits from a low-cost, large-area growth, ease

The use of an inorganic link, H2S, leads to two-dimensional assemblies of the Au quantum dots via a gas phase procedure. The morphology of the networks created in this way and the behaviour of the Au nanoparticles under H2S have been studied by scann

Some of the approaches previously used to perform reactions enantioselectively using heterogeneous catalysts, together with a few illustrative examples, are first briefly summarised. We then outline various advantages and opportunities that nowadays

The "staining" cluster-crown compound [Ru6 C(CO)14 (η6 -C6 H4 C10 H20 O6 )] verifies that the internal walls of mesoporous silica MCM-41 may be selectively functionalized with propylammonium groups (see picture). By the use of high-resolution transm

Als „Farbemittel” dient die Cluster-Kronenverbindung [Ru6C(CO)14(η6-C6H4C10H20O6)], indem sie an die selektiv mit Propylammoniogruppen funktionalisierte innere Oberflache des mesoporosen Silicats MCM-41 bindet (siehe Bild). Durch hochauflosende

High-performance, bimetallic nanoparticle catalysts (M1+M2) were obtained by gentle thermolysis of their precursor metal-cluster carbonylates physisorbed inside the mesoporous channels of silica (the hexagons in the figure). The Cu–Ru catalyst anch
