Microstructural evaluation and study of shock wave as an energetic source for synthesis of nanomaterials

Abstract

Over the past researches, the formulation of nanoparticles is considered to be a most time-consuming process. Accordingly, it is a relevant process to attempt the synthesis of the silica nanoparticle with a reasonable series of time. Therefore, shock wave as a source of energy has contributed an effective role in the field of material science. The research is motivated to reduce the processing time, and the alternative source of energy in the form of shock waves is intruded over the precursor and initiates the reaction in the precursor and also it is used to sustain and control the reactions of nanoparticles. In this research, an attempt has been made to use shock wave as a source of energy to synthesis silica nanoparticles. Henceforth, the processing time taken for the synthesis of silica is comparatively very high in the existing manufacturing schemes. Initially, the synthesis is initiated from the phase of material selection that is capable of the composition. Henceforth, tetraethyl orthosilicate, ethanol, water, ammonium hydroxide and shock tubes are the material participates in the composition. Accordingly, a disparate solution has been formed after the fusion of the relative materials. The prepared solution is treated with the consecutive shock pulses for the formation of the ammonium acetate and further treated in the centrifuge tube. Concurrently, on the basis of Fourier transform infrared spectroscopy (FTIR) the formation of silica nanoparticles is confirmed. Using field emission scanning electron microscope, the growth in the polymerization of silica nanoparticles is analyzed with a relative progress by inserting the shocks. Extensively, by acquiring the specified shock wave energy as an alternative solution the processing time attained for the synthesis will be more effectively performed when compared to the existing techniques as such that the existing practices will require 3 h to fulfill the synthesis as the proposed energy will attain only 15 min to formulate the nanoparticle. Ultimately, the FTIR analysis upon the research exhibits from the allotted region of the asymmetric vibration over basic intense band of silica is rectified as Si–O–Si over 1100–1120 cm⁻¹ and also deliberates a bending vibration with vibration of the corresponding Si–O–Si at 1670–1677 cm⁻¹, respectively. Conclusively, the research rectifies an immense of evolution in the processing time to synthesis silica nanoparticle from the existing practices followed in real-time scenario, respectively.
