Photocatalytic performance of Fe‐substituted ZnAl2O4 powders under sunlight irradiation on degradation of industrial dyes

“…Therefore, the oxidation procedure can be accomplished, causing the disintegration of chemical contaminants. 76,77 With the existence of organic compounds, the process of photocatalysis for metal alumina (MAl 2 O 4 ) under sunlight can be specified as below:…”

Effect of Cu2+ ions on structural, morphological, optical and magnetic behaviors of ZnAl2O4 spinel

“…In particular Zn-Cu spinel aluminates exhibit supreme magnetic properties depend on the percentage of Cu 2+ ions in zinc aluminate. Great resistivity, higher initial permeability and large magnetic saturation of Zn-Cu aluminates make them as better candidate for several applications such as inductors, electrical switch, microwave latching device, transformers, antenna cores and memory devices, etc [20][21][22]. Generally zinc aluminates spinel were synthesized by different ways like hydrothermal [14,23], sol-gel, co-precipitation route [24], solid-state reaction [25,26] and microwave combustion [27].…”

Pristine and Graphene-Quantum-Dots-Decorated Spinel Nickel Aluminate for Water Remediation from Dyes and Toxic Pollutants

“…Aluminates have high thermal stability, mechanical resistance, hydrophobicity and low surface acidity. Nickel aluminates are one of the most important aluminate materials, and have been studied for their many applications, including electrochemical sensing [1], pigments [2], catalysts [3][4][5][6][7], photocatalysts [8][9][10][11][12], magnetic [13] and refractory materials [14]. NiAl 2 O 4 has also attracted attention as a hydrogen storage material [15,16], oxygen carrier in combustion loop reactors [17] and as a component of supercapacitor electrode materials [18].…”

“…NiAl 2 O 4 has also attracted attention as a hydrogen storage material [15,16], oxygen carrier in combustion loop reactors [17] and as a component of supercapacitor electrode materials [18]. Very recently, attention has been focused on its photocatalytic performance [10][11][12]. First reports described the utilization of nickel-aluminum layered hydroxides for carbon dioxide conversion [19,20] and for dye degradation [21,22].…”

“…The photocatalytic activity of the nickel aluminate spinel against a series of dyes (i.e., rhodamine B (RhB), methylene blue (MB), methyl orange (MO), methyl red) was demonstrated by T. Tangcharoen et al [10]. In the past year, the enhanced photocatalytic performance of NiAl 2 O 4 was achieved by its substitution with copper, nickel and magnesium ions [11,12]. These photocatalytic tests were run against MB, MO and Congo red, both using ultraviolet and solar light irradiation.…”
