Metalloporphyrins-functionalized carbon nanotube networked films for room-temperature VOCs sensing applications (original) (raw)

Procedia Chemistry, 2009

Abstract

Networked films of carbon nanotubes (CNTs) have been grown by Chemical Vapor Deposition (CVD) technology onto cost-effective alumina substrate, coated by Cobalt nanocatalyst for growing the CNTs. The sidewalls of the CNTs films have been functionalized by spray-coating with two different metalloporphyrins (MPP), consisting of a Tetraphenylporphyrin coordinated by a central metal of zinc (Zn-TPP) and manganese (Mn-TPP). The surface-modification
