What is it about?
This research article unveils an eco-friendly, cost-effective, and non-toxic green synthesis route for synthesizing TiO2 nanoparticles. Sphagneticola trilobata, a dry leaves extract, is used as a reducing agent in combination with TTIP precursor. The article is dedicated to the efficient utilization of abundant plants, the reduction of toxic chemicals, and the meticulous examination of the prepared nanoparticles' photocatalytic activity. The prepared nanoparticles are subjected to a thorough characterization processes and photocatalytic tests on methylene blue (MB).

Why is it important?
XRD confirms the nanoparticles' tetragonal structure, and UV-vis reveals the maximum optical absorbance of the TiO2 at about 304 nm. The calculated band gap from the Tauc equation is about 3.093 eV, FTIR analysis demonstrates the stretching and bending vibration of the functional groups, and SEM analysis depicts the nanoparticles’ size at about 30.458 nm with a spherical shape. EDS analysis ensures the particles' purity as only Ti and O peaks are detected. The photodegradation rate is about 0.00583 min-1; it is about 57.06% degraded at about 160 minutes. In summary, this article presents a pioneering and eco-friendly green synthesis route to synthesize TiO2 nanoparticles, demonstrating remarkable photocatalytic activity on methylene blue.
Perspectives
I think this work contribute a vital impact on the field of nanomaterials. The investigated results ignite a spark of imagination, hinting at the potential applications in dye degradation, water purification, oil treatment, the textile industry, and medical science. The utilization of plant parts, such as leaves, stems, fruits, flowers, etc., for nanoparticle synthesis in the eco-friendly green chemistry approach enhances economic viability and promotes sustainable management, thereby increasing their attractiveness.
