We report -morphology oriented facile yet scalable route to synthesize 1D (nanorod) and 2D (nanobelt) MoO₃ nanostructures at gram scale using conventional as well as sonochemistry assisted sol-gel technique. The structural, morphological and optical properties of the samples can be befittingly altered by varying the synthesis protocol. The resultant orthorhombic MoO₃ nanomorphs demonstrated efficient and expeditious photocatalytic degradation of the pollutant dye, Methylene Blue (MB). We have observed that appreciable photocatalytic MB dye-degradation can be accomplished within 30 minutes with high rate constants of 0.0786 min and 0.233 min for rod and belt-like MoO₃-nanostructures, respectively. The pilot results indicate that the resultant MoO₃ nanomorphs can be potentially used as solar light driven industrial photocatalyst material with their photostability.
我们报告了一种形态导向的简便且可扩展的路线，可使用常规和超声化学辅助溶胶-凝胶技术在克级规模上合成 1D（纳米棒）和 2D（纳米带）MoO₃纳米结构。通过改变合成方案，可以适当改变样品的结构、形态和光学性质。所得的正交 MoO₃纳米形态表现出对污染物染料亚甲蓝（MB）的高效和快速光催化降解。我们已经观察到，在 30 分钟内可以完成可观的光催化 MB 染料降解，棒状和带状 MoO₃-纳米结构的速率常数分别为 0.0786 min 和 0.233 min。初步结果表明，所得的 MoO₃纳米形态可用作太阳能驱动的工业光催化剂材料，具有光稳定性。
