Special Issue Information
Dear Colleagues,
The escalating global challenges of air pollution, industrial emission control, and climate change have intensified the demand for precise and reliable gas detection technologies. Advanced chemical sensors play a pivotal role in monitoring hazardous gases (e.g., HCHO, NOX, VOCs, methane) and enabling real-time environmental quality assessment, industrial safety protocols, and public health protection. To address these needs, advanced chemical sensors must exhibit high sensitivity, selectivity, rapid response, and cost-effectiveness while operating under diverse environmental conditions.
Recent advances in materials science and nanotechnology have revolutionized gas-sensing capabilities. Innovations in nanostructured materials (e.g., 2D materials, metal–organic frameworks, conductive polymers), hybrid nanocomposites, and microfabrication techniques have unlocked unprecedented opportunities to enhance sensor performance. Additionally, the integration of machine learning for data analysis and the development of IoT-compatible devices are driving the evolution of smart, autonomous sensing systems. For this Special Issue, we encourage the submission of papers that utilize in situ/operando characterization techniques—such as X-ray absorption spectroscopy (XAS), near-ambient pressure X-ray photoelectron spectroscopy (NAP-XPS), diffuse reflectance infrared Fourier transform spectroscopy (DRIFTS), and Raman spectroscopy—to systematically probe gas–molecule interactions at sensing interfaces. These approaches are critical for elucidating dynamic structural evolution (e.g., crystal phase transitions, valence state modulation), identifying reactive intermediates, and mapping mechanistic pathways that govern sensor performance under realistic operating scenarios.
We welcome original research, reviews, and perspectives that bridge fundamental science with practical applications, aiming to accelerate the transition of laboratory breakthroughs into scalable, sustainable solutions.

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 2000 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.
