Abstract. Uniform, vertically aligned multiwalled carbon nanotube arrays (VACNTs) were grown on glassy carbon-like thin films by thermal chemical vapour deposition (CVD). Thin (5 nm) aluminum and iron catalyst layers were pre-deposited by evaporation on the carbon substrates and VACNTs were grown at 750 oC by water-assisted CVD using ethylene as the carbon source. The aluminum layer was s…
Abstract A tethered ligand-modified Rh/SiO2 catalyst was developed for hydroformylation with high stability. The catalyst was prepared by fastening both organic ligand and metal directly on the surface of support to avoid leaching, while at the same time the active species were formed in situ by coordination of the flexible ligand to the metal on the surface of SiO2. The immobilization of l…
