Dear Colleagues,

The precise detection of greenhouse gases and volatile organic compounds (VOCs), such as carbon dioxide, methane, nitrous oxide, ozone, benzene, and toluene, in meteorology, weather forecasting, libraries, electronics, food processing, packaging, the automobile industry, paper and textile technology, clinical diagnosis through breath monitoring and agricultural field is continuously endorsing the interest in realizing promising gas sensors. In particular, the last decade has witnessed the unprecedented growth of multifunction nanomaterials in designing miniaturized sensing devices for precise, real-time detection of various harmful analytes. The mesoporous architecture of the sensing layer remains the prominent factor behind the development of highly sensitive, selective, ultrafast responsive sensors, which have excellent reversible interactions with the targeted analyte molecules. The mesoporous nanostructure is particularly important for its high intrinsic surface area, pore volume, excellent thermal stability, and is interconnected with tunable pore channels, which provide easier adsorption and facile transportation of gas molecules across their surfaces.

This Special Issue aims to present recent developments in the processing methodology of any form of mesoporous functional nanomaterial, such as metal oxides, graphene, halide perovskites, and other novel 2D materials. Improvement of the gas-sensing performance of these materials, especially sensitivity, selectivity, as well as working conditions against specific chemical compounds, should be given special attention. The sensing process and mechanism involved and the use of these materials in real-world sensing platforms could be explored.

We invite researchers working on this area to submit their most recent research studies to this Special Issue. Full papers, communications, and reviews are all very welcome.

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 100 words) can be sent to the Editorial Office for announcement on this website.

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. Chemosensors is an international peer-reviewed open access monthly 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 2700 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.
