Fenton-like degradation of Rhodamine B over Fe2O3–Al2O3-zeolite hybrids derived from coal fly ash

Recent Findings on Fly Ash-Derived Zeolites Synthesis and Utilization According to the Circular Economy Concept

“…X-ray Diffraction (XRD) is used to determine the crystalline structure and phase composition of zeolites. It provides information about the arrangement of atoms in the zeolite framework and helps identify different zeolite phases [118]. It is a valuable tool in the determination of the efficiency of synthetic zeolite synthesis methods [7].…”

“…The recycling of coal FA offers a promising opportunity to create highly efficient Fenton-like catalysts capable of removing organic contaminants from wastewater effectively [118]. An additional product of synthesis might include a magnetic type which could be used as a substrate in nano-iron synthesis [109].…”

“…Fourier Transform Infrared Spectroscopy (FTIR) is used to identify the chemical bonds and functional groups present in zeolite materials, providing information about their composition and surface properties [118,126]. 6.…”

Nanoscale Solutions: The Transformative Applications of Functionalized Nanomaterials in Environmental Remediation

“…Metal and metal oxide nanoparticles (gold, silver, copper, silica, iron oxides, titanium oxides, zinc oxide, manganese oxide, etc.) and their bimetallic combination [22,27,28] or metal-organic frameworks and zeolites [29,30] showed the ability to adsorb several pollutants. Noble metal nanoparticles, especially gold (AuNPs) and silver nanoparticles (AgNPs) are used for the adsorption and catalytic degradation of antibiotics owing to their high surface reactivity and superior reaction kinetics [31].…”
