Abstract

Nowadays, due to extensive emission of toxic gases into our environment, gas sensors are extensively used for the detection of various gases mainly to increase our safety. AWO₄ (A = Zn, Ni) are semiconductor materials with relatively low-cost and abundant, and have stability and good electrical properties. So far, no review paper has been devoted to gas sensing properties of AWO₄ (A = Zn, Ni) gas sensors and they are subject of present review paper. We have paid attention to different aspects of these materials as gas sensors. They are being used in pristine form for the detection of various gases. Furthermore, decoration with noble metals is a popular strategy to enhance their sensing properties. Doping is another feasible route, and finally composite making is widely used to boost their sensing features. We have discussed the sensing mechanism of these sensors in detail. We believe that ZnWO₄ and NiWO₄ gas sensors are very promising materials for sensing purposes thanks to their unique electrical characteristics.

AWO4 （A= Zn, Ni）钨酸盐金属气体传感器研究进展

如今，由于有毒气体大量排放到我们的环境中，气体传感器被广泛用于检测各种气体，主要是为了提高我们的安全。AWO4 （A = Zn, Ni）是一种成本相对低廉且储量丰富的半导体材料，具有稳定性和良好的电学性能。到目前为止，还没有关于AWO4 （A = Zn, Ni）气体传感器的气敏性能的综述文章，因此是本文的主题。我们已经关注了这些材料作为气体传感器的不同方面。它们以原始的形式被用于检测各种气体。此外，用贵金属装饰是一种流行的策略，以提高其传感性能。掺杂是另一种可行的途径，最后是复合材料的广泛应用，以提高其传感特性。我们详细讨论了这些传感器的传感机理。我们认为，由于ZnWO4和NiWO4气体传感器具有独特的电特性，因此它们是非常有前途的传感材料。
