文摘
- •
Pure and Pt-doped SnO2 hollow spheres were prepared by nanoscale Kirkendall diffusion.
- •
Pure SnO2 hollow nanospheres showed high response to ppm-level ethanol.
- •
Pt-doped SnO2 hollow spheres showed ultrahigh response and selectivity to ethanol.
- •
Nanoscale Kirkendall diffusion can be used to prepare high performance gas sensors.
