Abstract

In this paper, we present highly sensitive thin film nanocomposite electrodes for electrochemical sensors. The nanocomposite electrodes are obtained on the porous PTFE substrate by magnetron sputtering co-deposition of the graphite/platinum target. As a result, the thin film nanocomposite electrode consists of an amorphous carbon matrix which includes platinum metal nanoclusters (a-C/Pt). The electrochemical gas sensors with the developed electrodes are produced and tested in several gas atmospheres. Experimental results demonstrate that a-C/Pt has higher sensitivity as compared to traditional powder catalysts.
