Wet chemistry route for the decoration of carbon nanotubes with iron oxide nanoparticles for gas sensing
In this work, we investigated the parameters for decorating multiwalled carbon nanotubes with iron oxide nanoparticles using a new, inexpensive approach based on wet chemistry. The effect of process parameters such as the solvent used, the amount of iron salt or the calcination time on the morpholog...
