Nanoscale Material-Based Gas Sensors

Dear Colleagues,

Nanomaterials are nano-sized materials with large specific surface areas and special physical, chemical and electrical properties. Gas sensors made of nanomaterials have the advantages of high sensitivity, high selectivity and fast response, and have been widely used in environmental monitoring, medical diagnosis, chemical production and other fields. However, the performance of such sensors is significantly influenced by the morphology and structure of the sensing materials. A wide variety of nanomaterials have been developed to improve gas sensing properties, such as sensitivity, selectivity, stability, and response speed.

This Special Issue aims to cover the recent advances in the design and fabrication of nanomaterial-based gas sensors, focusing on the nanomaterials’ design of current state-of-the-art gas sensors, which have achieved new records in sensitivity, stability, and selectivity. We will highlight the methods of fabrication for these devices and relate their nanomaterials to their record performance to provide a pathway for the gas sensors that will follow. The different types of nanostructured gas sensors, including catalytic, electrochemical, thermally conductive, and optical gas sensors, will be discussed, together with their gas sensing mechanisms and potential applications.

In this Special Issue, original research articles and reviews are welcome. Research areas may include (but not limited to) the following:

• Nanomaterials’ design of current state-of-the-art gas sensors;
• The methods of fabrication for gas devices;
• Gas sensing mechanisms and potential applications.

We look forward to receiving your contributions.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 250 words) can be sent to the Editorial Office for assessment.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Nanomaterials is an international peer-reviewed open access semimonthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2400 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
