Abstract
The current study evaluates the photocatalytic, structural, morphological, optical, and magnetic characteristics of the NixCoxMgxCuxZn1-4xO nanomaterials (x = 0.000–0.010). The NixCoxMgxCuxZn1-4xO nanomaterials were synthesized using the temperature-assisted co-precipitation technique. The characteristics of the NixCoxMgxCuxZn1-4xO nanomaterials were investigated using X-ray diffraction (XRD), Field emission scanning electron microscopy (FE-SEM), Fourier transform infrared spectroscopy (FTIR), UV–Vis spectroscopy, and Vibrating sample magnetometer (VSM). XRD analysis revealed dopant incorporation into the ZnO crystal structure, affecting lattice parameters. Magnetic behavior transitioned from diamagnetic to a combination of diamagnetic and ferromagnetic with increasing dopant levels. The optical band gap decreased as dopant concentration increased. Notably, the nanomaterial with x = 0.001 exhibited optimal photocatalytic performance, degrading 98.9 % of Rhodamine B within 20 min under UV light. This nanomaterial also showed efficacy against Methyl Orange and Congo Red, with hydroxyl radicals playing a crucial role in pollutant removal. These findings provide the exceptional reusability and stability of the NixCoxMgxCuxZn1-4xO nanomaterials (x = 0.001)
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.
