摘要

在目前的工作中，MoO3 - MoO2纳米复合材料是通过水热法合成的，并使用各种最先进的技术进行表征。XRD和FESEM观察到样品的高结晶度，显示出具有六角形面的二维片状层状结构。在所制备的复合材料在室温下进行乙醇传感，观察到该材料在25 ppm乙醇下表现为4.5%，响应时间为98 s，恢复时间为219 s。复合材料MoO3 - MoO2的响应较小，响应恢复时间较长，这可能是由于所观察到的原纤维较大。

Synthesis, characterisation and ethanol sensing applications of MoO3 – MoO2 nanostructures at room temperature

In the present work, MoO3 - MoO2 nanocomposite is synthesised via hydrothermal method and is characterised using various state-of-the-art techniques. The high crystallinity of the sample is observed from XRD and FESEM reveals the 2D plate like layered structures with hexagonal facets. The prepared composite is subjected to ethanol sensing at room temperature and it is observed that the material exhibits 4.5% for 25 ppm ethanol with response time as 98 s and recovery time as 219 s. The observed small response of the composite material MoO3 – MoO2 with longer response-recovery time might be due to the large sized fibrils observed.
