[en] Hydrogen sulfide is a toxic, highly corrosive and pollutant gas, but also a key-biomarker in disease diagnosis trough breath analysis. Its detection at very low level is therefore relevant and can be achieved with chemiresistors. The present works proposes a solution consisting in a facile synthesis of CuOloaded SnO2 hollow nanospheres deposited on interdigitated electrodes (IDEs). Synthesis, chemical and electrical characterization,
deposit process of the sensing layer and gas sensing capabilities of the sensing platform are presented. CuO loaded SnO2 sensing platforms achieved a successful sub-ppm detection at an operating temperature of 100 degrees Celsius.
