Efficient RhB degradation using MnFe2O4/g-C3N4 composites under visible light irradiation

Recent advances in spinel ferrite-based magnetic photocatalysts for efficient degradation of organic pollutants

“…Similar to type-II heterojunction, during light irradiation, electrons move to less negative CB while holes move to less positive VB due to the internal electric field, resulting in prolonged charge carrier lifetime and promoted photocatalytic activity. Xie et al prepared MnFe 2 O 4 /g-C 3 N 4 and evaluated the photocatalytic activity by Rhodamine B photodegradation (Xie et al 2022). The composite with 30 wt% MnFe 2 O 4 exhibited the highest photocatalytic activity under visible light.…”

Understanding Graphitic Carbon Nitride as Photocatalyst: A Case Study on Thermal Engineering of Physical and Chemical Features

“…[16] In this work, we present a systematic and rigorous investigation correlating the outcomes of photocatalytic (under both UV and simulated solar light) degradation of a popular molecular model (Rhodamine B [RhB]) and the thermally induced changes in crystalline structure, porosity, optical properties, photoluminescence (PL) lifetime of g-C 3 N 4 synthesized through urea thermal decomposition. This synthetic approach is quite popular in the literature, [17][18][19][20][21][22] as possibly the easiest and cheapest way to access g-C 3 N 4 , being thus extremely appealing for large-scale DOI: 10.1002/pssa.202300844 Rationalizing material features according to the adopted synthetic strategy, aiming then to tune them on demand, is among the most relevant purposes of investigation in materials science. Herein, the systematic analysis of the dependence of graphitic carbon nitride (g-C 3 N 4 ) physical characteristics on the decomposition temperature of urea, rationalizing the impact of synthetic temperature on several characteristics of the materials (degree of N-H condensation, carbon vs nitrogen content, structural parameters, photoluminescence lifetime, surface area, pores volume), is discussed.…”

This synthetic approach is quite popular in the literature, [ 17–22 ] as possibly the easiest and cheapest way to access g‐C 3 N 4 , being thus extremely appealing for large‐scale preparation. Different synthetic conditions result in different properties of the obtained material (in terms of chemical composition, crystallinity, N–H condensation, surface area, and so on), which eventually determine the skills of g‐C 3 N 4 as functional material.…”

Structural, Optical, Magnetic and Photocatalytic Properties of Zn Doped CoFe2O4Decorated Bentonite Nanocomposites

“…MFe 2 O 4 (M=divalent metal ions, egg Co, Zn, Ni, Cu, Cd, Mn, Mg, etc.) as monocrystalline spinel ferrites have attracted great attention for their magnetic, electrical, optical, photocatalytic, and biomedical properties and their outstanding applications in industry, medical science, and other scientific fields [24–30] …”

“…as monocrystalline spinel ferrites have attracted great attention for their magnetic, electrical, optical, photocatalytic, and biomedical properties and their outstanding applications in industry, medical science, and other scientific fields. [24][25][26][27][28][29][30] It was found that while cobalt ferrite has an inverted cubic spinel structure with Co 2 + substitution in the octahedral lattice region, Fe 3 + is equally distributed between the octahedral and tetrahedral lattice regions. [31][32][33] The properties of spinel ferrites (such as photosensitivity and electrical properties) are closely related to cationic substitutions, formulation, and synthesis methods.…”
