Surface Modification of Carbon Nanotube Networked Films with Au Nanoclusters for Enhanced Gas Sensing Applications
Figure 4
(a) Time response of the NO2 gas chemiresistor
based on Co grown RF-PECVD MWCNT films, functionalized with Au-loading of 2.5,
5, and 10 nm, at working temperature of 200°C. The MWCNTs thickness is about 250–300 nm. The inset
plots the calibration curves for four CNT sensors toward NO2 gas at
200°C. (b) Time response of the NO2 gas chemiresistor based on Co grown
RF-PECVD 250–300 nm-thick
MWCNT films, functionalized with Au-loading of 5 nm at working temperature of
250°C.
