以乙二醇为溶剂，采用溶剂热法合成了具有高活性（002）晶面的γ-单斜晶系WO 3纳米多层膜。多层WO 3具有独特的结构，其中较大的骨架纳米片从两侧被较小的纳米片夹在中间。由于优先暴露的高活性（002）面，所获得的电极在1.25 V（相对于Ag/AgCl（pH 6.8））下显示出1.62 mA cm-2的光电流密度，并且在AM 1.5 G下显示出0.154%的光转换效率。
This article describes the synthesis of γ-monoclinic WO3nanomultilayers with highly reactive (002) facets exposed through a facile solvothermal method using ethylene glycol as the solvent. The multilayered WO3exhibits a unique structure where a larger backbone nanosheet is sandwiched by smaller nanosheets from both sides. The obtained electrode showed a photocurrent density of 1.62 mA cm−2at 1.25 V versus Ag/AgCl (pH 6.8) and a photoconversion efficiency of 0.154% under AM 1.5 G owing to the preferentially exposed highly active (002) facets.
