Visible Light Responsive Nitrogen Doped Anatase TiO_2 Sheets with Dominant {001} Facets Derived from TiN

摘要

Anatase TiO_2 sheets with dominant {001} facets are becoming a hot research topic due to their promising high reactivity in heterogeneous reactions. Since the first successful preparation of single crystal anatase TiO_2 sheets with 47% {001} facets synthesized by us, several studies have extended this new route to synthesize more TiO_2 sheets as candidates for photocatalysis applications. Very recently, the percentage of {001} facets in anatase TiO_2 sheets was improved to 64% by employing an alternative solverthermal route. Meanwhile, Wu et al. reported nanostructured anatase TiO_2 with high-energy {001} facets via a nonaqueous synthetic route, and Han et al. demonstrated the nanosized titania sheets with 89% (001} facets.
