Special Issue Information

Dear Colleagues,

Chemoresistive gas sensors are steadily attracting increasing attention, even though they have been investigated and commercialized since 1970. This technology is mainly based on the development and use of nanostructured Metal OXide Semiconductors (MOXS) as sensing materials, which act both as receptors and transducers in the sensing mechanism. Sensors based on MOXS highlight very interesting features, i.e., high sensitivity, low cost, small size, low-power consumption and amenability of large-scale production through microfabrication methods and easiness of integration. All these peculiarities have allowed researchers to develop devices that find their way to the market, providing solutions to many applications. Nevertheless, MOXS gas sensors showed performance weaknesses, such as low selectivity and high working temperature, which still limited their widespread employment in several utilizations.

Recently, a huge effort has been devoted by researchers to develop and investigate new advanced nanostructured semiconductors that can overcome the above-mentioned MOXS limitations.

Some of these innovative non-MOXS materials highlighted noteworthy features, such as exceptional electronic properties and great and specific chemical reactivity, which result in optimal sensing performance, including high sensitivity and selectivity, and low activation temperature (2D materials, metal organic frameworks, carbon nanotubes, polymers, etc). The aim of this Special Issue is to broaden and deepen the use and knowledge on innovative non-MOXS sensing materials.

Accordingly, this Special Issue will cover topics on gas sensing beyond MOXS. You are invited to contribute with relevant reviews and original research articles focused on:

  • Development of novel non-MOXS materials and sensing strategies
  • Investigation of sensing performance of non-MOXS nanostructure unexplored so far
  • Understanding the sensing mechanism in non-MOXS and advances in investigation techniques
  • Development of non-MOXS-based sensing platforms for specific applications
