“…Similarly, Aravind and coresearchers [156] employed jasmine flower extract for the production of TiO 2 nanoparticles. Devikala and his team [157] achieved the production of nano-TiO 2 particles using Caesalpinia pulcherrima flower extract and TiOSO 4 . XRD analysis showcased the anatase TiO 2 phase and tetragonal structure of the obtained nanoparticles, while SEM and TEM analysis revealed asymmetrical sphere-shaped nanoparticles within a size range of 20-25 nm.…”

Contemporary technological and industrial advancements have led to increased reliance on chemicals for product innovation, leading to heightened contamination of water sources by traditional pollutants (organic dyes, heavy metals) and disease-causing microorganisms. Wastewater treatment processes now reveal “emerging pollutants”, including pharmaceuticals, endocrine disruptors, and agricultural chemicals. While some are benign, certain emerging pollutants can harm diverse organisms. Researchers seek cost-effective water purification methods that completely degrade pollutants without generating harmful by-products. Semiconductor-based photocatalytic degradation, particularly using titanium dioxide (TiO2), is popular for addressing water pollution. This study focuses on recent applications of TiO2 nanostructures in photocatalysis for eliminating various water pollutants. Structural modifications, like doping and nanocomposite formation, enhance photocatalyst performance. The study emphasizes photocatalytic elimination mechanisms and comprehensively discusses factors impacting both the mechanism and performance of nano-TiO2-based photocatalysts. Characteristics of TiO2, such as crystal structure and energy band-gap, along with its photocatalytic activity mechanism, are presented. The review covers the advantages and limitations of different TiO2 nanostructure production approaches and addresses potential toxicity to human health and the environment. In summary, this review provides a holistic perspective on applying nano-TiO2 materials to mitigate water pollution.

“…Green synthesis merupakan salah satu metode sintesis nanopartikel yang murah dalam segi biaya dan tidak beracun karena pada prosesnya menggunakan bahan-bahan biologi seperti mikroorganisme, biomolekul, ekstrak dari tanaman sebagai zat penstabil dan membantu mengurangi limbah berbahaya [8,[12][13][14]. Penggunaan bahan-bahan yang ramah lingkungan dapat memberikan manfaat terhadap keamanan lingkungan [12], karena dalam prosesnya meminimalkan penggunaan bahan yang beracun, tekanan, energi dan suhu yang tinggi [15]. Green synthesis merupakan pendekatan bottom-up, dimana ekstrak tanaman yang mengandung vitamin, mineral, asam amino, karbohidrat, dan protein berperan sebagai penstabil ukuran dan bentuk partikel nano [4,16].…”

In this study, TiO2 nanoparticles were synthesized without adding extract (0% v/v) (control) and with the addition of Gunung Omeh orange peel extract with various concentration, namely 4% v/v, 10% v/v, and 20% v /v. This study aims to study the use of Gunung Omeh orange peel extract on the formation of TiO2 nanoparticles and determine its characteristics. The characteristics of the resulting nanoparticles were characterized using X-Ray Diffraction (XRD), Diffuse Reflectance Spectroscopy, Ultraviolet-Visible (DRS UV-Vis), Scanning Electron Microscopy-Energy Dispersive X-Ray (SEM-EDX), Brunauer-Emmett-Teller (BET), Fourier Transform Infrared (FTIR), and Thermo Gravimetric and Differential Thermal Analyzer (TG-DTA). XRD results showed that the TiO2 phase formed was anatase. The optical property of TiO2 nanoparticles showed that the obtained TiO2 nanoparticles absorb in the UV region (200-400 nm). The results of SEM-EDX show that the resulting TiO2 nanoparticles are spherical. Meanwhile, the TOKJ20 sample has increased agglomeration so that the particle shape is rod-like. The EDX spectrum showes the presence of Ti and O peaks indicated the formation of TiO2. The results of BET measurement showed that the control TiO2 had a larger surface area of 66.11 m2/g compared to TiO2 using the addition of other orange peel extracts. From the results obtained, it was concluded that, in general, the addition of orange peel extract did not significantly affect the formation of TiO2 nanoparticles.
