Description
Air pollution has become one of the most pressing global challenges, demanding the development of highly sensitive, selective, and energy-efficient gas sensing technologies for environmental monitoring, industrial safety, and public health. Among emerging sensing materials, transition metal dichalcogenides (TMDs) have attracted significant attention owing to their unique electronic properties, high surface-to-volume ratio, and exceptional surface reactivity. The book highlights the role of nanostructure engineering, heterointerfaces, and surface interactions in enhancing the sensitivity, selectivity, stability, and room-temperature operation of chemiresistive gas sensors.
Drawing upon original research on molybdenum disulfide, molybdenum diselenide, and molybdenum ditelluride-based nanocomposites, this monograph discusses material synthesis, structural and electronic characterization, sensing mechanisms, and device performance, while emphasizing scalable thin-film fabrication techniques for next-generation gas sensor technologies.
