摘要

制备了一种用于室温下ppb级乙醇传感的掺银MoSe2纳米材料传感器。采用水热法合成了mosse2和ag修饰的mosse2纳米花，具有较高的纯度和结晶度。采用SEM、TEM、XRD、XPS等表征技术对Ag-MoSe2样品的微观形貌和微观结构进行了综合分析。银修饰MoSe2纳米材料由多个纳米片组装而成的纳米花组成。气敏结果证实，与原始MoSe2相比，ag修饰的MoSe2传感器在室温下对乙醇具有较低的检测限(10 ppb)和良好的响应/恢复特性，可用于饮用者的酒精检测。为了进一步验证和解释感应机制，通过基于密度泛函理论(DFT)的第一性原理研究模拟了原始和掺银MoSe2的吸附构型。有趣的是，与原始MoSe2体系相比，Ag-MoSe2体系表现出优异的乙醇传感性能，这与实验结果一致。这项工作提出了实验和DFT模拟的结合，以证实ag掺杂的MoSe2纳米花是室温下低浓度乙醇检测的有希望的候选物。

Room temperature ethanol gas-sensing properties based on Ag-doped MoSe2 nanoflowers: experimental and DFT investigation
An Ag-doped MoSe2 nanomaterial-based sensor was fabricated for ppb-level ethanol sensing at room temperature. The MoSe2 and Ag-modified MoSe2 nano-flowers were synthesized by a hydrothermal method, which exhibited high purity...
