Surface Modification of Carbon Nanotube Networked Films with Au Nanoclusters for Enhanced Gas Sensing Applications
Figure 5
Comparison of mean sensitivity of the MWCNT chemiresistor,
unmodified and Au-loaded of 2.5, 5, and 10 nm, toward NO2 and NH3 gas at working temperature of 200°C. The MWCNTs thickness is 250–300 nm and the
nominal thickness of Co growth-catalyst is 6 nm. The exposure time is 10
minutes.
