以十二烷基硫酸钠（SDS）为模板剂，通过电沉积法合成了具有层状结构的介孔WO3薄膜（见图）。与用异丙醇代替SDS制备的无孔WO3相比，层状介孔WO3具有更高的光催化活性和更大的嵌氢电流密度，这可能是由于介孔WO3具有更大的比表面积和更容易的电荷传输。
Mesoporous WO3 films with a lamellar structure (see Figure) have been synthesized by electrodeposition using sodium dodecyl sulfate (SDS) as a templating agent. Compared to non-porous WO3 prepared with isopropanol instead of SDS, lamellar phase mesoporous WO3 showed higher photocatalytic activity and greater current density for hydrogen intercalation, probably due to the larger surface area of mesoporous WO3 and more facile charge transport.
