Synthesis and characterization of TiO2/ZnO/SiO2 nanocomposite using pyrrolidinium-based ionic liquids via sol–gel-hydrothermal method for photocatalytic removal of Pb (II) ions
This study aims to synthesize TiO2 with precise particle morphology, a large surface area, a stable anatase phase at high temperatures, and enhanced catalytic activity in the visible light spectrum. TiO2 was combined with ZnO and SiO2 to form a TiO2/ZnO/SiO2 composite (TZS). A TiO2/ZnO/SiO2 composite (TZS) was synthesized via sol–gel-hydrothermal method at 180 °C for 24 h employing a water-pyrrolidinium-based ionic liquid mixture. XRD analysis confirmed anatase, zincite, and amorphous silica phases post-calcination at 450 °C. Compared to water alone, TZS synthesized with the water-ILs media exhibited higher surface area and narrower band gap energy. TG-DTA analysis confirmed anatase phase stability up to 1000 °C. SEM and TEM images showed TZS particles synthesized using water as spherical, while the water-ILs mixture produced nanocoral, nanorod, and nanocubic morphologies. In photocatalysis, TZS synthesized with water-ILs removed Pb(II) ions by 99.98 %, surpassing water-synthesized TZS at 95.49 % indicating superior photocatalytic of TZS synthesized with water-ILs.
期刊介绍：
The journal provides an international medium for the publication of theoretical and experimental studies and reviews related to the electronic, electrochemical, ionic, magnetic, optical, and biosensing properties of solid state materials in bulk, thin film and particulate forms. Papers dealing with synthesis, processing, characterization, structure, physical properties and computational aspects of nano-crystalline, crystalline, amorphous and glassy forms of ceramics, semiconductors, layered insertion compounds, low-dimensional compounds and systems, fast-ion conductors, polymers and dielectrics are viewed as suitable for publication. Articles focused on nano-structured aspects of these advanced solid-state materials will also be considered suitable.
