“…The peak depicted at 3384 cm −1 is attributed to the stretching vibration associated with the phenolic hydroxyl group present in the isolated lichen extract 19 . The bands observed in the range of 1631 cm −1 correspond to the stretching vibration of the carboxyl group which is also present in the isolated lichen extract 20 . Furthermore, the peak observe at 1383 and 1284 cm −1 representing the C─H stretching vibration and C─O─C linkage 21 .…”

The present investigation reports an effective, environmentally benevolent method for the removal of pharmaceutical waste from the contaminated water. Popular fluoroquinolone antibiotic prulifloxacin residue was taken as a sample of contaminant. Different irradiation conditions were used to explore the ability of TiO2 nanoparticles in the photodegradation of prulifloxacin. Aqueous lichen extract was used to fabricate the TiO2 nanoparticles. The assessment of the physical and chemical properties of the fabricated materials was examined by using well‐established analytical methodologies. The UV–vis spectra depicted the surface plasmon resonance peak at 282 nm. The XRD spectra revealed the particle nature of the developed nanomaterials and the result of the XRD spectrum depicted that the average diameter of the fabricated materials was found to be in the range of 20–30 nm. The FTIR spectra depicted the characteristic band at 750 cm−1, which corresponded to the Ti─O stretching mode of vibration. The SEM micrograph of the developed nanoparticles exhibited the irregular morphology of the developed nanoparticles. The present report critically analyzes the possible route of the degradation of prulifloxacin in the presence of microwave‐assisted green synthesized TiO2 NPs. The photodegradation of the prulifloxacin was not notably influenced by reactive oxygen species. Diverse analytical techniques were utilized to perform the structural analysis of the photoproduct. Results of the proposed investigation indicate that the rate of the photodegradation of prulifloxcin is highest when the drug is irradiated at 310 nm light in the presence of TiO2 NPs.

“…Water contamination is primarily caused by organic pollutants, e.g., carbon-based substances, which can originate from various sources, such as agricultural processes and industrial waste. In contrast, inorganic pollutants are typically derived from heavy metals or other materials that do not contain carbon [2].…”

Environmental photocatalysis of wastewater is an important application of TiO 2 nanoparticles (NPs). This paper reports the microwave-assisted green synthesis of TiO 2 NPs using the isolated extract of Permelia perleta lichen. Development of TiO 2 NPs was confirmed using Fourier transform infrared spectroscopy, X-ray diffraction analysis, scanning electron microscopy, and ultraviolet-visible (UV-Vis) spectroscopy. The acquired TiO 2 NPs were utilized as a nano photocatalyst in the degradation of acridine orange and phenol red dyes as model organic pollutants. The degradation efficiency of the developed TiO 2 NPs was evaluated using a UV-Vis spectrophotometer. We found that the acquired TiO 2 NPs had an average particle size of 30-40 nm, and the nanoparticles were somewhat agglomerated and are nonuniform in shape. The developed nano photocatalyst degraded the selected dyes efficiently, and the degradation efficiency was much better when the test sample was irradiated with UV light with a wavelength of 310 nm.
