Tuning the structural and optical parameters of Li1.2Ni0.4Fe2O4 for efficient degradation of dye and pharmaceutical compounds
Sol-gel auto-combustion route was used for the fabrication of lithium and dysprosium co-doped nickel ferrite (LNDFO). The composite of LNDFO with gCN (LNDFO@gCN) was prepared via ultra-sonication method. The synthesized samples were tested by photodegrading organic pollutants. Different characterization techniques were employed to examine the structure, morphology, elemental composition, and bandgap of prepared photocatalysts. The optical bandgap energy of LNFO, LNDFO, and LNDFO@gCN was 2.92 eV, 2.73 eV, and 2.64 eV, respectively. LNDFO@gCN had the lowest recombination rate of charged species and greater surface area, which makes it an efficient photocatalyst. The degradation shown by LNDFO@gCN for panadol, MB, and phenol was 90.04 %, 93 %, and 89.5 % respectively. EIS and Mott-Schottky analysis revealed that the charge transfer resistance of fabricated composite was less than bare and doped samples, and they were n-type semiconductor materials. As compared to all fabricated photocatalysts, LNDFO@gCN was most efficient photocatalyst due to its high degradation ability, easy formation, and higher charge separation rate.
期刊介绍:
The Journal of Molecular Structure is dedicated to the publication of full-length articles and review papers, providing important new structural information on all types of chemical species including:
• Stable and unstable molecules in all types of environments (vapour, molecular beam, liquid, solution, liquid crystal, solid state, matrix-isolated, surface-absorbed etc.)
• Chemical intermediates
• Molecules in excited states
• Biological molecules
• Polymers.
The methods used may include any combination of spectroscopic and non-spectroscopic techniques, for example:
• Infrared spectroscopy (mid, far, near)
• Raman spectroscopy and non-linear Raman methods (CARS, etc.)
• Electronic absorption spectroscopy
• Optical rotatory dispersion and circular dichroism
• Fluorescence and phosphorescence techniques
• Electron spectroscopies (PES, XPS), EXAFS, etc.
• Microwave spectroscopy
• Electron diffraction
• NMR and ESR spectroscopies
• Mössbauer spectroscopy
• X-ray crystallography
• Charge Density Analyses
• Computational Studies (supplementing experimental methods)
We encourage publications combining theoretical and experimental approaches. The structural insights gained by the studies should be correlated with the properties, activity and/ or reactivity of the molecule under investigation and the relevance of this molecule and its implications should be discussed.
