在180°C、无模板的条件下，通过简单的水热合成方法成功制备了宽度均匀的正交相三氧化钼（α-MoO 3）单晶纳米带，并用X射线衍射、场发射扫描电镜和透射电镜对其进行了表征.所合成的α-MoO 3纳米带沿c轴方向沿着生长。由于α-MoO 3纳米带具有较大的长径比，因此在紫外光照射下，α-MoO 3纳米带对亚甲基蓝的降解具有很高的光催化活性。催化剂在5次循环后光催化活性损失不明显。
Single crystal orthorhombic phase molybdenum trioxide (α-MoO 3 ) nanobelts with uniform width have been successfully prepared through a simple hydrothermal synthesis route at 180°C in the absence of any template, and are characterised using X-ray diffraction, field emission scanning electron microscopy and transmission electron microscopy. The synthesised α-MoO 3 nanobelts are grown along the c -axis direction. The α-MoO 3 nanobelts for degradation of methylene blue in aqueous solution exhibit high photocatalytic activity under UV light irradiation because of the large aspect ratio of α-MoO 3 nanobelts. The photocatalytic activity loss of the catalyst is not obvious after five recycles.
