Abstract

Present work aims to use pioneer fuels as a reducer for fabricating CaFe₂O₄ via combustion synthesis (CS) as a potential adsorbent for dye adsorption. CaFe₂O₄ was innovatively synthesized by a CS using fuels, glycerol (Gly), ethylene glycol (EG), and diethylene glycol (DEG). The AF adsorption was comprehensively investigated using nine isotherm and four kinetic models to establish the adsorption process and mechanism by optimizing adsorption efficiency. Characterization of adsorbents was analyzed using XRD, FTIR, VSM, BET, and FESEM. The fuels significantly influenced the surface properties and morphology of CaFe₂O₄. The DEG-CaFe₂O₄ exhibits multi-dimensional spongy morphology compared to the blocky and irregular structure of EG-CaFe₂O₄. The Langmuir adsorption capacity of the CaFe₂O₄ was found to be in order DEG-CaFe₂O₄ (1223) > Gly-CaFe₂O₄ (1101) > EG-CaFe₂O₄ (987 mg/g) following the transition in surface morphology rather than surface area. The pseudo-second-order (PSO) kinetic and the Langmuir isotherm model demonstrate the Acid fuchsin (AF) dye uptake. The present study showed that the fuel has a significant role in the morphological properties of CaFe₂O₄ in the CS, which significantly influences the AF adsorption efficiency.

期刊介绍： Polyhedron publishes original, fundamental, experimental and theoretical work of the highest quality in all the major areas of inorganic chemistry. This includes synthetic chemistry, coordination chemistry, organometallic chemistry, bioinorganic chemistry, and solid-state and materials chemistry. Papers should be significant pieces of work, and all new compounds must be appropriately characterized. The inclusion of single-crystal X-ray structural data is strongly encouraged, but papers reporting only the X-ray structure determination of a single compound will usually not be considered. Papers on solid-state or materials chemistry will be expected to have a significant molecular chemistry component (such as the synthesis and characterization of the molecular precursors and/or a systematic study of the use of different precursors or reaction conditions) or demonstrate a cutting-edge application (for example inorganic materials for energy applications). Papers dealing only with stability constants are not considered.
