Surface Modification of Carbon Nanotube Networked Films with Au Nanoclusters for Enhanced Gas Sensing Applications
Figure 8
Time online responses of two chemiresistors based on
unmodified CNTs and 10-nm loaded Au-modified CNTs (CNTs_Au-10 nm), exposed to
30-minute pulses of NO2 gas ranging from 100 to 600 ppb, at sensor temperature of 200°C. The thickness of CNTs films is about 250–300 nm.
