Abstract

We report a preparation of titanium dioxide regular nano-polyhedron with reactive (001) facets by simple yet efficient hydrothermal synthesis process. It has been found that the (001) surfaces are terminated with F atoms, and the F-terminated surfaces, which reduce the surface energy of anatase titanium dioxide, provide a stable condition for the existence of (001) facets. Ni doping, additionally, restrict the growth of particle, making the morphology of anatase titanium dioxide regular plus uniform. Besides, the as prepared titanium dioxide with high reactive (001) facets exhibit far better gas sensing performance over ethanol than those mainly having exposed (101) facets. Such a facile method and interpretation mechanisms could be applicable to many other nanomaterials for a wide range of study.
