Abstract

A continuous, single-step, and large-scale preparation of Pd-catalyst-loaded SnO2 yolk–shell spheres is demonstrated. These nanostructures show an unusually high response and selectivity to methyl benzenes, such as xylene and toluene, with very low cross-responses to various interfering gases, making them suitable for precise monitoring of indoor air quality.
