MetalMetal-Oxide Nanoclusters for Gas Sensor Applications

الملخص EN

The development of gas sensors that are based on metal/metal-oxide nanoclusters has attracted intensive research interest in the last years.

Nanoclusters are suitable candidates for gas sensor applications because of their large surface-to-volume ratio that can be utilized for selective and rapid detection of various gaseous species with low-power consuming electronics.

Herein, nanoclusters are used as building blocks for the construction of gas sensor where the electrical conductivity of the nanoclusters changes dramatically upon exposure to the target gas.

In this review, recent progress in the fabrication of size-selected metallic nanoclusters and their utilization for gas sensor applications is presented.

Special focus will be given to the enhancement of the sensing performance through the rational functionalization and utilization of different nanocluster materials.
