合成了一种类似于4-5 nm厚度的单晶WO 3纳米片，对应于沿c轴沿着的六个单斜WO 3重复晶胞，其具有使用固液相电弧放电路线在水溶液中形成的微小WO 3纳米晶体的横向取向附着。这种纳米结构中的尺寸量子化效应改变了WO 3的带隙，使纳米片能够在烃燃料中存在水的情况下表现出增强的光催化还原CO2的性能，所述烃燃料不以其本体形式存在。
An ultrathin, single-crystal WO3 nanosheet of similar to 4-5 nm in thickness, corresponding to six repeating unit cells of monoclinic WO3 along the c axis, was synthesized with laterally oriented attachment of tiny WO3 nanocrystals formed using a solid liquid phase arc discharge route in an aqueous solution. Size quantization effects in this ultrathin nanostructure alter the WO3 band gap to enable the nanosheet to exhibit enhanced performance for photocatalytic reduction of CO2 in the presence of water in hydrocarbon fuels that do not exist in its bulk form.
