An electronic or optical device that detects the presence of particular gas or liquid molecules (such as humidity, NO, hydrogen, etc.) is known as a zinc oxide nanorod sensor or ZnO nanorod sensor. in the surrounding environment.
The sensor makes use of the increased surface areaâand, as a result, surface activityâof ZnO nanorods and other nanomaterials. Variation in the nanorods' properties, such as photoluminescence, electrical conductivity, vibration frequency, mass, and so on, can be used to detect molecules adhering to them.
Passing electrical current through the nanorods and observing the changes caused by gas exposure is the simplest and most common method. Hydrothermal synthesis can be achieved by combining a 1:1 Molar solution of hexamine and a solution of zinc nitrate for 56 hours in an autoclave at 60-70 degrees Celsius.
Due to their remarkable performance in electronics, optics, and photonics and their unique material properties, ZnO nanowires (also known as nanorods) have been the subject of extensive research.
ZnO nanowires' photocatalytic applications in environmental protection have recently attracted more attention. Due to its superior physicochemical properties, ZnO is extensively utilized as a gas sensing material for detecting harmful and toxic gases. The use of zinc oxide nanoparticles (ZnO NPs) in cosmetics, paint, rubber, and other industrial products is on the rise.
TheGlobal ZnO Nanorod sensor marketaccounted for $XX Billion in 2023 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2024 to 2030.
Due to their wide range of conductance variability, response to both oxidative and reductive gases, and highly sensitive and selective properties, the ZnO nanorods developed by RIKEN KEIKI have been widely used for gas detection at low concentrations.
This chapter provides a comprehensive overview of ZnO nanorod fabrication techniques, controllable growth, various configurations, modifications for enhancing sensing property, and composites for gas sensors.
Hydrothermal synthesis, microemulsion synthesis, microwave-assisted hydrolysis preparation, gas-solution-solid synthesis, spray pyrolysis, sonochemical synthesis, simple solution synthesis, and others are some of the synthesis methods used to create ZnO nanorods.
Control growth, selective growth, and diameter regulation are all methods that can be used to produce ZnO nanorods in a manner that can be controlled. Cross-linked configuration, flower-like structure, multishelled hollow spheres, and hollow microsemispheres are among the various structures that influence the sensing properties of ZnO nanorods.
Doping, functionalization, decoration, sensitization, and other modifications can be made to ZnO nanorods to improve their sensing properties. Core-shell composites for gas sensors can be made with ZnO, carbon nanotubes, graphene, SnO2, In2O3, and Fe2O3.
