Palladium nanoclusters were observed (HRTEM) on SnO2 nanoparticles modified with high dose of Pd. The electrical performances of the sensors coated with this Pd-nanoclustered sensing material reveal an important improvement of the selectivity for CO and CH4. As result, CO, CH4 and mixtures of them can be distinguished in a wide range of humidity (from 20 to 80%) with a unique sensor working in a pulsed temperature modulation
