摘要: Metal oxide nanoparticles, such as CuO and SnO2, are outstanding systems for H2S gas sensing in air. In this work, those nanoparticles were deposited with different mixing percentages on substrates to form percolating networks of nanoparticles. Electrical electrodes the nanoparticles’ films investigate their response against H2 H2S, electrical characteristics. The sensor devices based CuO–SnO2 revealed enhanced characteristics a sensitivity 10 ppm. could be attributed formation PN-junctions among SnO2 reasonable production cost (due simple structure cheap used materials), low power consumption ( ~ 1 µW at room temperature), high sensitivity, response, time present sensors qualify them practical implementation portable
