通过水热法合成了 0–3 mol% Gd 掺杂的 MoO3 纳米带，用作可见光驱动的光催化剂。研究了Gd掺杂对MoO3纳米带的物相、形貌和光催化活性的影响。 X射线衍射（XRD）和透射电子显微镜（TEM）结果表明，纯产物和掺Gd产物均为正交晶系MoO3和掺Gd MoO3纳米带，其生长均沿[001]方向生长。通过亚甲基蓝 (MB) 溶液在可见光辐射下的降解来监测 0–3 mol% Gd 掺杂的 MoO3 纳米带的光催化作用。 Gd掺杂MoO3纳米带比纯MoO3纳米带表现出更好的光催化性能。 3 mol% Gd 掺杂 MoO3 光催化剂表现出最高的可见光驱动活性，60 分钟内 MB 溶液的光降解率达到 99%。
0–3 mol% Gd-doped MoO3nanobelts were synthesized by hydrothermal method for using as visible-light-driven photocatalysts. The effect of Gd dopant on phase, morphologies and photocatalytic activities of MoO3nanobelts was investigated. The X-ray diffraction (XRD) and transmission electron microscopy (TEM) results show that pure and Gd-doped products are orthorhombic MoO3and Gd-doped MoO3nanobelts with their growth along the [001] direction. Photocatalysis of 0–3 mol% Gd-doped MoO3nanobelts were monitored through degradation of methylene blue (MB) solutions under visible radiation. The Gd-doped MoO3nanobelts show better photocatalytic performance than pure MoO3nanobelts. The 3 mol% Gd-doped MoO3photocatalyst exhibits the highest visible-light-driven activity for photodegradation of MB solution of 99% within 60 min.
