Impact of single domain configuration on photocatalytic dye removal in cerium-substituted cobalt ferrite nanoparticles
This paper discusses the impact of single domain realization on the performance of dye removal-photocatalyst of Congo Red. Cerium-substituted cobalt ferrite (CoCe0.1Fe1.9O4) nanoparticles preparing coprecipitation-route with varying annealing temperatures were used in this experiment. The XRD characterization and Rietveld-fullprof analysis showed that the diffraction pattern was in accordance with ICDD no. ICDD 22–1086 showed a face-centered cubic (fcc) structure with a space group of Fd-3 m, which is the pristine crystalline structure of cobalt ferrite. Calculation of the crystallite size D in hkl (311) orientation using the Scherer equation shows that increasing the annealing temperature promotes a larger of the D. The FTIR results show the presence of two typical absorption peaks within the range of v1 ∼ 400/cm and v2 ∼ 600/cm which indicates the absorption of metal oxide belonging to spinel cobalt ferrite. VSM results show that the magnetic properties are modified by annealing temperature. The largest coercive field Hc = 3.62 kOe for the non-annealed (NA) sample indicated the presence of a single domain configuration. TEM results show the presence of fine nanoclusters for the NA sample and disappear after the annealing process, which is indicated to support the presence of a single domain configuration. Micromagnetic simulations were also performed to evaluate the effect of domain configuration (single or multi domain) on the coercive field. Finally, the NA sample presented the highest dye removal performance of 97.47 %, which suggested the contribution of single domain realization in the photocatalytic process.

期刊介绍:
Results in Physics is an open access journal offering authors the opportunity to publish in all fundamental and interdisciplinary areas of physics, materials science, and applied physics. Papers of a theoretical, computational, and experimental nature are all welcome. Results in Physics accepts papers that are scientifically sound, technically correct and provide valuable new knowledge to the physics community. Topics such as three-dimensional flow and magnetohydrodynamics are not within the scope of Results in Physics.
Results in Physics welcomes three types of papers:
1. Full research papers
2. Microarticles: very short papers, no longer than two pages. They may consist of a single, but well-described piece of information, such as:
- Data and/or a plot plus a description
- Description of a new method or instrumentation
- Negative results
- Concept or design study
3. Letters to the Editor: Letters discussing a recent article published in Results in Physics are welcome. These are objective, constructive, or educational critiques of papers published in Results in Physics. Accepted letters will be sent to the author of the original paper for a response. Each letter and response is published together. Letters should be received within 8 weeks of the article''s publication. They should not exceed 750 words of text and 10 references.
