The fundamental principle of Fourier Transform Infrared (FTIR) spectroscopy is based on the vibration and rotation atoms, it has become a universal widely used spectral methodology for detection internal molecular structures in diverse range fields. A considerable number review articles pertaining to applications FTIR have been published recent years. Nevertheless, comprehensive summary application nanoparticles’ (NPs’) green synthesis yet be presented. In present paper, we propose series case studies that demonstrate analysis metal oxide NPs synthesized using processes. Furthermore, presented position functional group bands spectra are responsible reduction, capping stabilization NPs. this review, explore advantages limitations methodologies overcoming these challenges. We also potential solutions complex spectra. intended serve as compendium information researchers engaged field NPs, utilizing research tool.

Achieving the smallest crystallite/particle size of zinc oxide nanoparticles (ZnO NPs) reported to date, measuring 5.2/12.41 nm with Justicia adhatoda (J. adhatoda) leaf extract, this study introduces a facile green synthesis. Utilizing aqueous J. extract as both reducing and stabilizing agent, method leverages plant's rich phytochemical composition produce highly crystalline morphologically controlled ZnO NPs. This precise particle control highlights effectiveness synthesis process in morphological tuning. The synthesized NPs were thoroughly characterized using XRD, UV-vis spectroscopy, FTIR, FESEM, HRTEM, which collectively revealed superior crystallinity, morphology, unique surface properties conferred by bio-capping. photocatalytic performance these biogenic was evaluated for degradation two model pollutants: malachite (MG), synthetic dye, 4-nitrophenol (4-NP), toxic organic compound. exhibited exceptional efficiency, achieving 99.8% MG within 180 minutes demonstrating rapid reduction 4-NP 4-aminophenol reaction rate constant 0.245 min-1 under UV sunlight irradiation. Mechanistic studies attributed high reactive oxygen species (ROS) generation electron-hole pair interactions, supported improved charge separation area. work not only establishes potential adhatoda-mediated addressing persistent pollutants but also sets benchmark size-controlled By delivering scalable eco-friendly water remediation technologies, advances nanotechnology.

In modern society where fossil fuel prices are increasing and environmental issues becoming more severe, biodiesel, as a new type of clean fuel, is receiving attention. Biodiesel has the advantages renewability, friendliness, good properties, demonstrating broad application prospects. However, use biodiesel also faces some challenges, such higher density kinematic viscosity, lower calorific value, etc. The nanoparticles in engines helps to achieve goal fuel. terms characteristics, increase cetane flash point improving combustion efficiency safety, but may affect combustion. can promote micro explosions secondary atomization improve cylinder pressure, heat release rate, brake thermal while reducing consumption. Nanoparticles reduce HC CO emissions, through oxygen reaction area, incomplete products. On contrary, CO2 emissions because better conditions oxidation reactions. For NOX temperature others emissions. Comparison shows that all offer varying degrees improvement engine performance provided by TiO2 significantly than other nanoparticles. future, synergistic effect multiple should be explored further achieving effects cannot achieved single nanoparticle.
