Regulating Photocatalytic Selectivity of Anatase TiO2 with {101}, {001}, and {111} Facets

Abstract: In this work, we demonstrate a novel approach to control the photocatalytic selectivity of TiO 2 though different dominant crystal facets. {101}, {111}, and {001} facets exposed nanoscale anatase TiO 2 were obtained by a simple hydrothermal route with different ratio of NH 4 + and F -, then a calcined progress to clear surface adsorbent atoms. Results reveal that {101} exposed TiO 2 has some remain binding N with a mode of unsaturated N 3c exhibits selectively photocatalytic degradation of methylene orange (MO… Show more

“…Since Fujishima demonstrated the photocatalysis with TiO 2 under UV‐light irradiation in 1970s, semiconductor‐based photocatalytic technique has been considered to be one of the reliable and ultimate solutions to dealing with global environmental pollution . TiO 2 is a famous semiconductor owning improved photocatalytic activities for the oxidative degradation of organic compounds . However, TiO 2 with band gap of 3.2 eV has poor nature solar efficiency and slow reaction rate, which hinders its further applications .…”

“…However, the poor light absorption and the rapid recombination of photogenerated electrons and holes still limit its photocatalytic efficiency and the practical applications . It has been proved that the construction of heterojunction through combination of two semiconductors is a promising technique to broaden responsive spectrum and suppress the charge recombination …”

“…[6] The high oxidization potential energy of OH radicals can induce many backward reactions, such as oxidizing the intermediates and products converted from the as-adsorbed CO 2 . [7,8] 4The photocatalytic treatment of high concentration organic pollutants from industrial waste poisons the photocatalyst resulting deactivation. In addition, it is difficult to separate a pure semiconductor oxide photocatalyst from the waste water treating system, [9] which further deactivates the photocatalysts.…”
