Abstract
Allura Red (AR) is a synthetic food colorant that is found in the wastewater of several food companies. It is utilized in drinks, syrups, and instant drink powders. In this study, 2D Zinc-Aluminum hexagonal layered double hydroxides (LDHs) were successfully synthesized and demonstrated to be an effective catalyst for AR degradation. In the presence of sodium borohydride (NaBH4), these synthesized LDHs demonstrated greater catalytic activity for AR degradation. According to the pseudo-first-order kinetic investigation, 2D Zinc-Aluminum hexagonal LDHs have excellent catalytic degradation activity toward AR. AR degradation rates can reach 77.03 % in 60 min, suggesting the fast catalytic efficacy of the resultant Zinc-Aluminum hexagonal LDHs in the presence of NaBH4. The experimental and DFT calculation findings revealed that an electric field existed between the surfaces, resulting in rapid electron movement. The outstanding catalytic activity indicates that Zinc-Aluminum hexagonal LDHs may have a good prospective use in organic dye wastewater treatment.
期刊介绍:
Ceramics International covers the science of advanced ceramic materials. The journal encourages contributions that demonstrate how an understanding of the basic chemical and physical phenomena may direct materials design and stimulate ideas for new or improved processing techniques, in order to obtain materials with desired structural features and properties.
Ceramics International covers oxide and non-oxide ceramics, functional glasses, glass ceramics, amorphous inorganic non-metallic materials (and their combinations with metal and organic materials), in the form of particulates, dense or porous bodies, thin/thick films and laminated, graded and composite structures. Process related topics such as ceramic-ceramic joints or joining ceramics with dissimilar materials, as well as surface finishing and conditioning are also covered. Besides traditional processing techniques, manufacturing routes of interest include innovative procedures benefiting from externally applied stresses, electromagnetic fields and energetic beams, as well as top-down and self-assembly nanotechnology approaches. In addition, the journal welcomes submissions on bio-inspired and bio-enabled materials designs, experimentally validated multi scale modelling and simulation for materials design, and the use of the most advanced chemical and physical characterization techniques of structure, properties and behaviour.
Technologically relevant low-dimensional systems are a particular focus of Ceramics International. These include 0, 1 and 2-D nanomaterials (also covering CNTs, graphene and related materials, and diamond-like carbons), their nanocomposites, as well as nano-hybrids and hierarchical multifunctional nanostructures that might integrate molecular, biological and electronic components.
