The adsorptive capacity of multiwall CNTs for copper species in water depends on the type of functional group present on their surface. The alcohol (OH) and acid (COOH) network forces formed by van der Waals bonds within the CNT bundles can define their aggregate state and available sites for copper adsorption. Copper is attracted to different oxygen radicals on the surface and within the bundles...
Carbon nanotubes (CNTs) is grown by the catalytic thermal Chemical Vapor Deposition (Cat-CVD) at temperatures of 500degC to 800degC. CNTs are characterised by Raman spectrometry, and scanning electron microscopy (SEM) images. The photocatalysis efficiency is improved by using CNTs on Ni/TiO2 surface where absorption and decomposition are promoted.
We investigated the effect of titanium (Ti)-coated carbon nanotubes (CNTs) theoretically and experimentally. We found that adsorption of single Ti atom lowers the work function of CNTs by density functional calculations. Also, Ti-coated CNTs showed the largest increase in local density of states around Fermi level under electric fields. Coating of Ti metal on CNTs was carried out by electroless plating...
