An Overview on Magnetic Separable Spinel as a Promising Materials for Photocatalysis and Waste Water Treatment

Abstract

In the recent times, the demand of the energy and the environmental pollution is the main concern of the global. Due to their significant chemical, physical and magnetic properties spinel-based materials are prominently used in the field of photocatalysis and water splitting. In the present report is emphasis on the fundamental's understandings for their size, shape, chemical and the degradation of various pharmaceutical drugs, pesticides, and textile dye materials. This report explained the way of formation, characteristics and the wide applications of the spinel-based materials in the vast energy and environmental research. Based on the future prospectus of the energy and the cost effectiveness this spinel-based materials plays an important role in hydrogen generation as well as in catalytic activities.

Novel Spinel Nanomaterials for Photocatalytic Hydrogen Evolution Reactions: An Overview

“…Xiaoxing Xu et al reported enhanced H 2 performance with Ga-doped ZnFe 2 O 4 , where Ga doping created trap states between the energy levels, hence increasing charge migration and band gap energy compared with the parent ZnFe 2 O 4 [67]. There is a strong correlation between catalytic activity and crystal structures along with all the physicochemical properties [68]. Moreover, the high-temperature calcination required for the pure-phase formation of spinel ferrite can eliminate the trapping sites for electrons and holes and hence can be avoided to decrease the recombination rates.…”

Facile development of copper ferrite nanospheres for UV light-driven photocatalytic degradation of cloxacillin sodium

“…It was previously found that CuFe 2 O 4 NPs were a 75% efficient photocatalyst for rhodamine B dye. 35 Since the physical properties of CuFe 2 O 4 nanoparticles such as phase transitions, electrical switching, semi-conductivity, magnetic properties, and chemical stability can alter in response to varying environmental circumstances, they are the ideal spinel ferrite. 36 CuFe 2 O 4 nanoparticles have been employed in the production of lithium-ion rechargeable batteries, magnetic resonance imaging materials, photocatalysts for hydrogen evolution using visible light, energy storage materials, coupling reaction catalysts, CO 2 reduction catalysts, photoanodes for solar water oxidation, supports for enzyme immobilization, and catalysts in nanomedicine for the treatment of breast cancer.…”

Effect of divalent ion of strontium substitution on the structural, optical, magnetic and blood compatibility studies in cobalt ferrite

“…The metal oxides are mixed in the form of a powder and then sintered in a furnace to form a ceramic material. Spinel ferrites are represented by a general formula AFe 2 O 4 , where A refers to the divalent metal cations [Ni 2+ , Cu 2+ , Mn 2+ , Zn 2+ , Co 2+ , etc], can be depicted as a closely packed cubic structure of oxygen atoms with A 2+ and Fe 3+ at two different crystallographic regions [1,2]. These regions are labelled as tetrahedral (A-site) and octahedral (B-site) oxygen coordination, respectively.…”
