Surface Modification of Carbon Nanotube Networked Films with Au Nanoclusters for Enhanced Gas Sensing Applications
Figure 7
Repeatability of the response of the unfunctionalized and
Au-5 nm modified MWCNT-based sensors toward 10-minute five pulses of (a) 10 and
1 ppm NO2 gas and (b) 1000 and 100 ppm NH3 gas at working
temperature of 200°C. The CNTs thickness is about 250–300 nm and the
nominal thickness of the growth-catalyst of Co is 6 nm.
