Abstract

This research presents an in-depth analysis of nanoparticle classification, highlighting the key attributes that inform their categorization: size, shape, and material composition. Among these, titanium dioxide emerges as a notable and technologically important substance within various fields of nanotechnology. The utilization of titanium dioxide nanoparticles is widespread, attributed to their thermodynamic stability, corrosion resistance, substantial photocatalytic activity, wide band gap, and high transmittance in both the visible and infrared spectra. In this investigation, TiO₂ nanoparticles were synthesized from titanium isopropoxide algae through hydrothermal methods. Characterization of the synthesized TiO₂ nanoparticles was conducted using Fourier-transform infrared spectroscopy (FTIR), UV-Visible spectroscopy, and Field Emission Scanning Electron Microscopy (FE-SEM), a sophisticated technique for capturing the microstructural images of materials. The TiO₂ nanoparticles displayed a range of morphologies, including spherical, ellipsoidal, and irregular shapes, with individual nanoparticle sizes and some aggregates measuring between 5 and 20 nm. This study concentrated on the synthesis growth of these nanoparticles and their potential applications. Researchers are modifying their methodologies to treat wastewater. The extraction of heavy metals such as mercury, lead, thallium, cadmium, and arsenic from wastewater sources has attracted considerable attention, given their harmful effects on both environmental and human health. The substantial volume of wastewater generated daily further underscores the urgency of this issue.
