[ 1 ] - Carbon Nanotubes Synthesis by Chemical Vapor Deposition of Methane over Zn – Fe Mixed Catalysts Supported on Alumina

Carbon nanotubes were synthesized over a series of Zn-containing Fe/alumina catalysts by chemical vapor deposition method at two reaction temperatures of 850 and 950 °C using methane as a carbon source. Catalysts were synthesized by keeping Fe concentration constant and varying Zn concentration to study the effects of Zn. The catalysts were characterized using X – ray powder diffraction and N2 ...

[ 2 ] - 8-Hydroxyquinoline grafted nanoporous SBA-15 as a novel solid phase extractor for preconcentration of trace amount of Copper

In this study, the potential of 8-Hydroxyquinoline grafted SBA-15 to extract of Cu<sup>2+ </sup>cations from aqueous solutions was investigated<em>. </em>SBA-15 nanoporous silica was chemically grafted with 8-Hydroxyquinoline groupsaccording to the procedure in the literature. The presence of organic groups in the silica framework was demonstrated by FTIR spectrum. The grafted product showed th...
