Special Issue Information
Dear Colleagues,
I am happy to invite you to contribute to a Special Issue that is devoted to the rapidly evolving field of gas-sensitive nanomaterials. Gas sensors play a crucial role in sectors like environmental monitoring, healthcare diagnostics, and industrial safety, where detecting specific gases such as NOx, greenhouse gases (GHGs), and volatile organic compounds (VOCs) is vital. Traditional materials like metal-oxide semiconductors and carbon-based nanomaterials have shown great promise in gas sensing due to their excellent physical/chemical properties and sensitivity towards various gases. However, these materials face challenges, such as limited selectivity, high operating temperatures, and interference from humidity. The utilization of advanced nanomaterials has the potential to address these limitations, resulting in better performance and greater reliability. Recent innovations in the field have introduced advanced nanomaterials, such as MXenes and metal–organic frameworks, offering exciting opportunities for enhanced gas sensing performance at low temperature. In addition to these advanced nanomaterials, the integration of machine learning into gas sensing technologies is enhancing data interpretation, calibration, and predictive modelling, optimizing the performance of advanced nanomaterials. This synergy promises to create more sensitive, selective, and reliable gas sensors for various applications. This Special Issue will explore these cutting-edge materials alongside traditional ones and highlight their ability to shape the future of gas sensing technologies.
The Special Issue aims to provide a comprehensive overview of the latest developments in gas-sensitive nanomaterials, focusing on their synthesis, characterization, and applications. Suggested research areas include, but are not limited to, the following:
- Synthesis and functionalization/doping of traditional gas-sensitive nanomaterials (e.g., metal-oxide semiconductors, carbon nanotubes, graphene) for detecting specific gases (e.g., NOx, NH3, GHGs, VOCs);
- Nanocomposites and hybrid materials for enhanced gas sensing performance;
- Advanced MXene and metal–organic framework-based gas sensors: Design, synthesis, and applications;
- Sensing mechanisms and optimization strategies for high-performance gas sensors;
- Theoretical and computational modelling of gas sensing behaviour in nanomaterials;
- Enhancing accuracy and efficiency by optimizing gas sensor performance using machine learning.
