Abstract

This paper presents the sub-ppm level electrical detection of H2S gas at room temperature using printed copper acetate-gold nanoparticle composite films. The excellent sensitivity of these films towards H2S can be attributed to the catalytic activity of gold nanoparticles in combination with the plasma oxidation of copper acetate films.
