Iron hydroxide nanowires are a type of nanomaterial composed of iron oxide and hydroxide molecules. They are produced through a process of electrochemical deposition, where an electric current is passed through an aqueous solution containing iron ions and hydroxide ions.
As the current is passed through the solution, iron hydroxide molecules form and attach to each other to create long, thin nanowires. These nanowires typically have a diameter of 10-100 nanometers and a length of up to several millimeters.
Iron hydroxide nanowires are of great interest to scientists due to their unique properties and potential applications. They are highly electrically conductive and can be used in the production of nanoscale electrical components. They are also highly magnetic, and can be used as nanoscale magnets.
In addition, they are highly stable and corrosion-resistant and can be used as corrosion barriers in a variety of industrial and engineering applications. Finally, they are highly porous and can be used as nanoscale filters, sorbents, and catalysts.
Iron hydroxide nanowires are also being studied for their potential use in the field of medicine. They have been shown to have antimicrobial properties and can be used to kill bacteria and other pathogens. They can also be used to deliver drugs and other therapeutic agents directly to cells, which could potentially be used to treat a variety of diseases.
The Global Iron Hydroxide Nanowire market accounted for $XX Billion in 2023 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2024 to 2030.
The development and manufacturing of 1D iron hydroxide/oxide nanowires has been the focus of much research. Even so, it is still difficult to manage the fabrication process to customise the size, shape, anisotropy, and crystallinity.
The successful commercialization and integration of devices need significant efforts to create efficient, environmentally friendly fabrication techniques that produce nanowires with scalability, repeatability, and stability.
To achieve this goal for promoting TMOS nanowire-based optoelectronic devices, a thorough understanding of fundamental guiding principles, including crystal growth mechanisms, kinetics, and phase transformation, is essential. This understanding should be maintained throughout the fabrication of metal-hydroxide/oxide nanowires. The electrical and optical properties of transition metal-oxide/hydroxide nanowires, as well as their various synthesis methods.
The excellent product purity, inexpensive manufacturing, and controllable dimensions make bottom-up approaches popular for producing transition metal oxide NWs. One can use either vapour phase growth strategy or solution phase strategy to fabricate transition metal hydroxide/oxide nanowires under control.
Many 1-D metal oxide nanostructures, such as nanowires, nanobelts, nanorods, and nanotubes made with vapour or solution phase growth techniques, have been compiled by Shen and colleagues.
But high-temperature vapour-phase techniques, such as vapour phase growth via processes like vapour–liquid–solid (VLS), vapour–solid–solid (VSS), or vapour–solid (VS) process, physical vapour deposition (PVD) and chemical vapour deposition (CVD), are costly and require specialised equipment. There is also the controlled pressure of the inert atmosphere.
In order to create metal oxide/hydroxide NWs, the wet chemical approach can be used to precipitate or oxidise the precursor with the use of a catalyst, surfactants, and heating in an oxygen-rich environment.
To create metal hydroxide/oxide nanowires by a hydrothermal approach, the precursor solution/substrate must be heated and then annealed in an oxygen atmosphere.
In order to use solvothermal procedures, a metal precursor solution must be heated to a high temperature while a solvent is present. Another effective technique is microwave assistance, which involves cooking food to a higher temperature in a microwave.
These most common wet chemical growth techniques, however, call for pricy chemicals, heating processes, lengthier reaction periods, templates, or contaminants that must be eliminated during the process.
