Data of nanocomposite
Description
A nanoparticle is a material with ultra-fine aspects of dimensions in the nanoscale. Its one-of-a-kind material makes it a significant player in the efficient working of the latest technologies. The latest technologies also have a very hazardous effect which is proved by the widespread illicit use of homemade explosives (HME). Microwaves are a type of electromagnetic radiation that assist the synthesis process which can be tuned to yield desired size and shape of Ferrous Oxide (Fe₂O₃) Nanoparticles (NPs). The energy of microwaves is too low to directly activate or break molecular bonds. Using this chemical advantage, this research aims to develop a detector with the combination of Ferrous Oxide (Fe₂O₃) and Manganese Oxide (MnO₂) NPs that will detect Hydrogen Peroxide (H₂O₂) based hazardous explosives.

Steps to reproduce
STEP-ONE: Synthesis of Fe₂O₃ Ferrous Oxide (Fe₂O₃) was extracted from a rusted material. One gram of Fe₂O₃ was weighed and dissolved in dilute H₂SO₄. After this, the solution was placed on a stirrer for 30 minutes at 850rpm. This was further placed in a microwave for 30 seconds which completed the synthesis of Fe₂O₃. The confirmation of sythesis was done by using UV Visible Spectrophotometer. The absorbance of the product was 425nm which confirms the preparation of Fe₂O₃ NPs. STEP-TWO: Synthesis of MnO₂ For MnO₂, one gram was dissolved in dilute H₂SO₄. After this, the solution was kept on the stirrer for 30 minutes at 850rpm. The confirmation of synthesis was done by using UV Visible Spectrophotometer. The absorbance of the product was 518nm which confirms the preparation of MnO₂ NPs. STEP-THREE: Preparation of Nanocomposite For preparing nanocomposite, 53% of MnO₂ NPs and 26% of Fe₂O₃ NPs is used. MnO₂ is placed in the reacting chamber and a probe is utilized to insert Fe₂O₃. Alongside, 21% of a dispersion medium (Lignin) is mixed in this. This solution is placed in the microwave. The cycle is repeated 6 times for the time duration of 30 seconds. The total waiting time and reaction time sums up to 9 minutes and 3 minutes respectively. Hence, the entire preparation of the nanocomposite completes in 12 minutes. This nanocomposite is mixed with increasing concentration of H₂O₂ starting with 30% concentration in order to detect its presence.
