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.
