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.

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.File in questo prodotto:
