Growth of CNTs on the Ni/TiO2 Surface by Catalytic CVD Method

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/TiO

surface where absorption and decomposition are promoted.
