Nanotechnological applications involving the fabrication of potential nanomaterials and novel strategies for mitigation of contaminants have helped a lot in environmental cleanup. The chemical route for silica nanoparticle (NPs) synthesis using tetra ethyl oxy silicone and tetramethyl oxy silicone is expensive and energy intensive. Silica NPs synthesis from coal fly ash waste could prove to be economical. In this study, the investigators have used coal fly ash for silica NPs synthesis via a noble and economical approach. This biosynthetic approach involved two steps: (1) extraction of crude sodium silicate by using alkali treatment of fly ash and (2) the addition of crude sodium silicate to the supernatant of Fusarium oxysporum for fabrication of silica NPs. The developed silica NPs are analyzed by the analytical instruments where the microscopic techniques revealed 10–50 nm‐sized floral‐shaped mycogenic silica NPs. The X‐ray diffraction revealed the amorphous nature of the silica NPs with a broad spectrum starting from 8º and ending at 23º having centered at 13.1°. Fourier transform infrared spectroscopy, in region 400–1200 cm−1, exhibited three distinguishing bands for silica NPs. The current study reports a novel and effective method for the development of silica NPs with a high yield and purity of about 95%.

An alternative technique is presented for the corrosion protection of the A36 structural steel (A36SS) in acid medium (H2SO4) using silica obtained from canary seed husk (CSH). The silica was obtained in a solid amorphous state with a particle size of 10–22 nm. The anticorrosive properties of nanosilica (NS) were studied using potentiodynamic polarization (PDP), linear polarization resistance (LPR), and electrochemical impedance spectroscopy (EIS). Before carrying out the corrosion tests, the A36SS was subjected to a treatment with NaOH solution without and with the presence of NS. The A36SS treated with NS presented the lowest current density values and the noblest corrosion potential values, indicating that the corrosion rate decreased. The surface morphological study of the tested systems using SEM/EDS showed that the NS‐treated A36SS had a more efficient physical barrier against corrosive species.
