The green synthesis of TbFeO3 nanostructures utilizes natural extracts from cherry and orange juice to produce highly crystalline, nanoscale particles. Unlike traditional synthesis methods that rely on toxic chemicals and energy-intensive processes, this approach employs the polyphenol and ascorbic acid content of fruit juices as natural reducing agents. The process involves mixing aqueous juice extracts with terbium and iron precursors to form a gel-like precursor, which is then calcined at high temperatures to yield orthorhombic TbFeO3 nanostructures with a perovskite structure. These nanostructures, typically 20-50 nm in size, exhibit high surface area and uniform particle distribution. Characterization through techniques like X-ray diffraction, scanning electron microscopy and Fourier-transform infrared spectroscopy confirms their phase purity, morphology and surface chemistry, making them ideal for photocatalytic applications. The use of fruit juices eliminates hazardous chemicals, enhancing the biocompatibility and environmental sustainability of the process. Under UV light, TbFeO3 nanostructures efficiently absorb radiation due to their narrow bandgap (around 2.1 eV), generating electron-hole pairs that drive the production of Reactive Oxygen Species (ROS) for dye degradation.
The photocatalytic mechanism of TbFeO3 involves UV light absorption, which excites electrons from the valence band to the conduction band, creating electron-hole pairs. These interact with water and oxygen to form ROS, such as Hydroxyl Radicals (â?¢OH) and Superoxide Radicals (O2â?¢â??), which effectively degrade the complex structures of organic dyes. The nanostructures achieve near-complete degradation of dyes like methylene blue within hours under UV irradiation, with efficiencies exceeding 90%. Their high surface area enhances dye adsorption, positioning pollutant molecules close to ROS for efficient breakdown. The magnetic properties of TbFeO3, stemming from its iron component, enable easy separation from treated water using an external magnetic field, supporting catalyst recovery and reuse. Compared to conventional photocatalysts like TiO2, TbFeO3 offers superior UV responsiveness and stability, with minimal photocorrosion across multiple cycles. The green synthesis method reduces the environmental impact of production, aligning with sustainability goals. By optimizing parameters like juice concentration and calcination temperature, the photocatalytic performance of TbFeO3 can be further enhanced, making it suitable for large-scale wastewater treatment [2].
