One step synthesis of Au-loaded SnO2-based nanocomposites for chemical gas sensors is presented. Flame spray pyrolysis (FSP) procedure with the use of originally designed setup was utilised to obtain either pure or Au-loaded materials. Superior gas sensor properties of obtained SnO2-Au nanocomposites compared to same way prepared pure SnO2 material are demonstrated. HAADF STEM microscopy was utilized to provide chemical insight into a degradation of gas sensor performance of given materials over time.
