Chemoresistive Gas Sensors Based on Noble-Metal-Decorated Metal Oxide Semiconductors for H2 Detection

Materials, Год журнала: 2025, Номер 18(2), С. 451 - 451

Опубликована: Янв. 19, 2025

Hydrogen has emerged as a prominent candidate for future energy sources, garnering considerable attention. Given its explosive nature, the efficient detection of hydrogen (H2) in environment using H2 sensors is paramount. Chemoresistive sensors, particularly those based on noble-metal-decorated metal oxide semiconductors (MOSs), have been extensively researched owing to their high responsiveness, low limits, and other favorable characteristics. Despite numerous recent studies reviews reporting advancements this field, comprehensive review focusing rational design sensing materials enhance overall performance chemoresistive MOFs lacking. This aims address gap by examining principles, applications, challenges with specific focus Pd-decorated Pt-decorated MOSs-based materials. The observations explanations strategies employed literature, within last three years, analyzed provide insights into latest research directions developments domain. understanding essential designing fabricating highly sensors.

Exploring the promise of one-dimensional nanostructures: A review of hydrogen gas sensors

International Journal of Hydrogen Energy, Год журнала: 2023, Номер 50, С. 1443 - 1457

Опубликована: Ноя. 19, 2023

Among different materials that have been used for hydrogen sensing, one-dimensional (1D) nanostructures shown promising results due to their enhanced specific surface area, nanoporosity and improved characteristics (in particular, uniformity stability) facilitate high number of active sites. This paper aims comprehensively review 1D nanostructure-based sensors from three aspects including: (1) Synthesis techniques: briefly overview the four primary synthesis techniques how critical processing parameters affect morphology sensing behavior, (2) Materials: properly distinguish mechanisms properties inorganic such as metal oxide semiconductors (MOS) combined/doped with organic carbon-based polymers, heterostructures can improve performance, (3) Enhancement schemes additive functionalisation, material composition light-assisted approaches further elevate characteristics. Future challenges are yet be investigated in this which is discussed enlighten way future explorations.
