In this work, one-dimensional (1D) α-MoO₃ nanobelts and Zr-doped α-MoO₃ nanobelts were facilely prepared via a simple hydrothermal method, and the gas sensing performance of the obtained products towards xylene vapor was tested systematically. The characterization results showed that Zr was successfully doped into the lattice of α-MoO₃ without destroying the unique 1D nanobelt structure and existed as ball-like nanostructures scattered on the nanobelts. The data from the gas sensing test demonstrated that the Zr-doped α-MoO₃-based sensor exhibited superior sensing performance with the response towards 100 ppm xylene at the optimum operating temperature of 206 °C reaching 7.99, which was nearly three-fold greater compared with that of the pristine α-MoO₃-based sensor. Besides, the Zr-doped α-MoO₃-based sensor possessed excellent selectivity and a low detection limit. The enhanced sensing performance could be attributed to the 1D nanostructure and the doped Zr. The mechanism of the enhancement of sensing properties induced by the Zr-doping strategy was also demonstrated specifically.

Zr掺杂对提高一维基于α-MoO3的二甲苯气体传感器的灵敏度和选择性的影响

在这项工作中，一维（1D）α-的MoO _3个纳米带和Zr掺杂的α-的MoO _3个中制备轻便纳米带通过一个简单的水热法，将得到的产品朝二甲苯蒸汽的气体感测性能进行了系统的试验。显示的表征结果的Zr被成功地掺杂到α-的MoO的晶格₃而不破坏独特1D纳米带结构和存在的作为球状散布在纳米带的纳米结构。从气体感测测试数据表明，该锆掺杂的α-的MoO ₃基于传感器显示出优异的感测性能在与206℃下的最佳工作温度达到7.99，与原始α-的MoO相比这是近三倍更大的朝向100ppm的二甲苯中的反应₃基传感器。此外，锆掺杂的α-的MoO ₃系传感器具有优异的选择性和低的检测限。增强的感测性能可以归因于一维纳米结构和掺杂的Zr。还具体说明了由Zr掺杂策略引起的增强传感特性的机理。
