Bismuth oxide nanoparticles were made through green synthesis. The process was carried out using Mentha pulegium extract. The green synthesis technique has attracted much attention in recent times. There is tremendous potential for this method in the cosmetic and pharmaceutical industries.
Bismuth oxide nanoparticles exhibit absorption peaks within the 200-400 nm range. This was due to formation of the bismuth oxide polymorph. Bismuth oxide nanoparticles also exhibited UV blocking abilities. They also had antibacterial property.
Bismuth oxide powder was made using a straightforward combustion technique. The powder was dried under vacuum. The surface's morphology was analyzed using FE-SEM. The atomic weight of bismuth oxide was 2.7 (eV).
The calcination time for superfine bismuth oxides of high purity took 612 days. The temperature of calcination was between 450 and 600 degrees Celsius. The powders are granular with sizes ranging from 0.1-0.5 millimeters.
The energy of the band gap in bismuth oxide powder was measured using a UV-DRS spectrum plot. Energy band gap of bismuth dioxide powder was 2.7 (eV).
Bismuth oxide nanoparticles displayed antibacterial properties against Gram-negative as well as Gram-positive bacteria. The UV protective properties were also assessed using diffuse reflection. The optimal time to synthesize nanoparticles was also determined using UV-Visible-based spectrophotometers, and Fourier change infrared-spectroscopy.
Bismuth oxide nanoparticles were able to exhibit good dispersibility. The UV-protection properties of bismuth oxide nanoparticles are due to their dynamic light scattering ability that the particles possess. Bismuth oxide powder is excellent dispersibility and purity making it ideal to be used in the electronic industry.
Synthesis of Bismuth Oxide Powder
Several techniques have been used to synthesize bismuth oxide powder. Hydrothermal methods are one of them. It can create powders with exceptional crystalline properties.
The spray pyrolysis method is yet another technique for making bismuth powder. It has been utilized in numerous applications, for instance, a gas sensing application. The electrospinning technique has also been utilized for the creation of nanofibers. Sol-gel is an alternative method that produces powders with a a narrow pore distribution.
The essential distributions of bismuth were observed by scan electron microscope. The crystal structure was confirmed with X-ray diffraction. Numerous spectroscopic techniques including dynamic light scattering, FT-IR, XRD and UV-Visible spectroscopy were employed to study the samples.
The spectrum of absorption in the UV-visible spectrum was researched to determine the UV protection properties of the nanoparticles. The wavelength of absorption for UV ranges between 250-700 nm. The absorption peak of bismuth oxide is at 292 nm.
The antibacterial capacity of the nanoparticles has also been studied using the method of disk diffusion. Bismuth's antibacterial properties oxide was tested for salmonella ATCC 1231. A disc was stained with different concentrations of samples. The size of the zone of inhibition was determined using an instrument called a ruler.
This green process for synthesising nanoparticles have attracted much attention in recent years. It has been utilized for different applications in the pharmaceutical and food industries.
Bismuth oxide nanoparticles are also used for UV blocking. They are of high purity and are useful for antibacterial action. Bismuth oxide is a photocatalyst with an absorption spectrum that is broad and is capable of eliminating organic molecules. It is also helpful for water purification.
Applications of Bismuth Oxide Powder
One of the numerous uses for bismuth oxide powder is metal surface treatment, plastics and coatings. It also plays an significant role in chemical vapor dispersion, thermal-evaporation in addition to electron beam devaporation.
Bismuth oxide nanoparticles can be investigated as radiosensitizers. Radiosensitizers increase the effect radiation on cell viability. This results in the destruction of DNA in cells.
Nanoparticles produced high surface area and can be used for target imaging. Nanoparticles also exhibit high radiopacity. Bismuth oxide nanoparticles are used in a variety of products, such as health devices, optical filter and magnetic field sensors. They can also be employed in traceable monitoring of bismuth accumulation.
Bismuth oxide nanowires having excellent crystalline properties have been produced through the induced stress process with low temperature. These materials are used as radiosensitizers Megavolt as well as Kilovolt the treatment of radiation.
Nanostructured bismuth materials have gained lots of attention because of the quantum properties of this material. They are also used in thermoelectric coolers, as well as optical devices.
Bismuth oxide has also been proven to be effective when applied to biological problems. Bismuth used in medical formulations is frequently used for stomach disorders. Bismuth is also utilized in astringentsas well as bacteriostatic agents as well as refrigerants. It has also been utilized in nuclear industry as refrigerant. It also serves as substitute for conductor in electronics.
Bismuth has been used in a variety of ways since the 19th century. But, the use of bismuth decreased in 20th century. This was due in part to reversible bismuth encephalopathy. There are, however, various treatments that need new technologies.
