Non-fluorinated synthesis of anatase TiO₂ with dominant {001} facets: influence of faceted structures on formaldehyde sensitivity

Abstract

The extraordinary surface, electronic and catalytic properties of titanium dioxide (TiO₂) is better manifested with highly exposed {001} facets. This article illustrates the synthesis of {001} faceted TiO₂ nanosheets through a non-fluorinated route and oxidation of formaldehyde on the {001} facets using the synergistic effect of crystal facet, gold nanoparticle and UV irradiation.
