“…This suggested more ionic behavior and reduced the bond length. 14 The locality of the electron density along the bond lengths, and the information it describes, suggest an influence on factors such as fluorescence efficiency and photocatalytic activity. Both, fluorescence efficiency and photocatalytic activity, relate to the ability of compounds to interact with light and in later stages further degrade due to this perturbation and interaction with light.…”

“…Many other groups have used the maximum-entropy method (MEMS) in analyzing the placement of the electron density distribution along paths between atoms. − MEM utilizes the electron density information from diffraction data by maximizing the entropy information where it can be used to analyze polymeric systems. − In one case, the electron density was distributed closer to the atoms versus the center of the bond. This suggested more ionic behavior and reduced the bond length . The locality of the electron density along the bond lengths, and the information it describes, suggest an influence on factors such as fluorescence efficiency and photocatalytic activity.…”

The development of reusable polymeric materials inspires an attempt to combine renewable biomass with upcycling to form a biorenewable closed system. It has been reported that 2,5-furandicarboxylic acid (FDCA) can be recovered for recycling when incorporated as monomers into photodegradable polymeric systems. Here, we develop a procedure to better understand the photodegradation reactions combining density functional theory (DFT) based time-dependent excited-state molecular dynamics (TDESMD) studies with machine learning-based quantitative structure−activity relationships (QSAR) methodology. This procedure allows for the unveiling of hidden structural features between active orbitals that affect the rate of photodegradation and is coined InfoTDESMD. Findings show that electrotopological features are influential factors affecting the rate of photodegradation in differing environments. Additionally, statistical validations and knowledge-based analysis of descriptors are conducted to further understand the structural features' influence on the rate of photodegradation of polymeric materials.

“…Another antibiotic, moxifloxacin, was photocatalytically degraded using CeO 2 /La 2 O 3 /TiO 2 nanocomposites [ 15 ]. A PbMoO 4 catalyst was employed for the degradation of ciprofloxacin, and a 100% degradation efficiency was observed [ 16 ]. Among these, one of the most commonly used antibiotics is cefixime trihydrate (CFX), which used to treat a variety of bacterial infections, including bronchitis and gonorrhea.…”

The present work was carried out to synthesize bismuth ferrite (BFO) nanoparticles by combustion synthesis, and to evaluate the photocatalytic activity of synthesized bismuth ferrite nanoparticles against cefixime trihydrate. BFO nanoparticles were successfully synthesized using bismuth (III) nitrate and iron (III) nitrate by a combustion synthesis method employing different types of fuels such as maltose, succinic acid, cinnamic acid, and lactose. The effects of the different types of fuels on the morphology and size of the bismuth ferrite nanoparticles were investigated. Characterization of the as-obtained bismuth ferrite nanoparticles was carried out by different techniques such as X-ray diffraction (XRD), scanning electron microscopy (SEM), Energy-Dispersive Spectroscopy (EDS), N2-sorption analysis, Fourier-transform infrared spectroscopy (FT-IR), and ultraviolet-visible (UV–vis) spectroscopy. Photoluminescence studies were also carried out for the various bismuth ferrite nanoparticles obtained. Degradation of cefixime trihydrate was investigated under sunlight to evaluate the photocatalytic properties of the bismuth ferrite nanoparticles, and it was found that the bismuth ferrite nanoparticles followed first-order degradation kinetics in solar irradiation in the degradation of antibiotic, cefixime trihydrate.
