Iron nanoparticles are very appealing materials which, with potential applications in many fields, including sensors, catalysis, and medicine. Each of these proposed uses is associated with unique physical properties which could be further tailored by engineering the shape or size of the nanoparticles.
The shape of iron nanoparticles can affect their magnetic behavior, leading to significant changes in how they interact with information carriers, such as magnetic recording media and the human body. Size-controllable nanoparticles can be used to produce more uniform catalysts by overcoming variations in particle size that often lead to less efficient reactions.
These properties can change drastically according to how many iron atoms are bound together into each nanoparticle, making the production of homogenous nanoparticles with narrow size distributions essential for their practical applications. Despite significant research efforts, the production of uniform nanoparticles is still a considerable challenge.
How are they produced?
A method has now been developed that allows controllable overproduction of homogenous iron nanoparticles by using catalytic chemical vapor deposition (CCVD). This technique was adapted to use methane as the carbon source to create the iron nanoparticles at low temperatures.
Iron nanoparticles are typically produced using hydrogen gas, which is known for having a significant effect on particle size and distribution. This study therefore first investigated how different precursors affect iron nanoparticle formation under CCVD conditions. Using methane as a carbon source meant that the particles formed at low temperatures. This allowed for the study of how temperature affects nanoparticle synthesis, which was not previously possible to achieve with other carbon sources used in iron nanoparticle synthesis.
The researchers found that increasing the precursor flow rate increased the mean size of the particles produced by 10%. Increasing methane concentrations had less significant effects, with increasing methane flow rates having no measurable impact on average particle size.
The effect of varying temperatures between 300 and 600°C was also assessed in this study using methane as a carbon source to form iron nanoparticles. While it has been widely reported that decreasing the temperature during chemical vapor deposition increases particle diameter, this work found that changing the temperature at high precursor flow rates did not affect changes in mean particle size or distribution.
Applications of Iron Nanoparticles
Here are some of the many advantages and applications of Nanotechnology:
- On eyeglasses, computer and camera displays, windows, and other surfaces, ultrafine films can make them water-resistant, residue-repellent, anti reflective, self-cleaning, UV or IR light-resistant, anti-fogging, antibacterial, scratch-resistant, or electrically conductive.
- Washable, long-lasting “smart fabrics” equipped with flexible nanoscale sensors and electronics
- The lightweight of cars, trucks, airplanes, boats, and space stations may result in significant fuel savings. The additives used in Nanoscience prove to be significant input products for a wide range of industries. Carbon nanotube sheets are now being developed for use in future aircraft. They’re ideal for applications like electromagnetic shielding and thermal management because of their lightweight and conductivity.
- More precise imaging and diagnostic instruments created using nanotechnology are leading to earlier detection, more personalized therapy choices, and higher therapeutic success rates.
