“…39 As shown in Figure 3a,b, BiOI is a p-type semiconductor and Fe 2 O 3 is an ntype semiconductor, and thus the Fe 2 O 3 /BiOI nanocomposites can be considered to be an n-p heterogeneous structure. According to previous reports, 40,41 the positions of the conduction band level (E C ) of Fe 2 O 3 and the valence band level (E V ) of BiOI are 0.08 and 2.22 eV (vs Ag/AgCl), respectively, and the corresponding E V and E C can be determined by the equation E C = E V − E g . E g in the equation has been calculated from the UV−vis spectra (Figure 2b), which are 2.10 and 1.97 eV.…”

We report a promising photoanode material of FeO/BiOI for efficient photoelectric conversion in solar cells, which was fabricated with BiOI attached to a one-dimensional FeO nanorod array. The two semiconductors of p-type BiOI and n-type FeO formed a heterogeneous structure for efficient charge separation. The highest open circuit voltage and short circuit current of the solar cell can reach 0.41 V and 4.89 mA/cm, respectively. This study opens an available field to develop low-cost and environmentally friendly photoelectric materials for solar cells.

“…In addition, g-C 3 N 4 contains a large number of nitrogen atoms, as its network is mainly composed of tertiary and aromatic amines, which also contribute to the stability of the metal particles by creating a tight coordination. Furthermore, the richness of the sp 2 (C–N) hybridized bond in the g-C 3 N 4 structure made it have good thermal and chemical stability . Muniandy et al reported that copper-modified graphitic carbon nitride nanosheets (Cu- g -C 3 N 4 ) have good catalytic activity toward liquid-phase-selective oxidation of benzene and various VOCs.…”

Graphitic carbon nitride (g-C3N4) supported CoOx catalysts were prepared by the impregnation method and comprehensively characterized by XRD, N2 physisorption, TEM, H2-TPR, and XPS. The catalytic performance tested by catalytic combustion of toluene indicates that 10% CoOx/g-C3N4 catalyst exhibits the highest activity, achieving a toluene conversion of 90% at a temperature of approximately 279 °C, compared with other CoOx catalysts supported on SBA-15, γ-Al2O3 and activated carbon (AC). The specific structure of g-C3N4 made it a N and electron-rich material, which might be the reason for the existence of Co3O4 active phase, high surface Co3+ content and high density of surface oxygen adsorption species, and facile reducibility of Co3+. Moreover, no significant decrease in catalytic efficiency is observed over different temperature stages on the 10% CoOx/g-C3N4 sample, which indicates that the catalyst’s stability is excellent under the conditions required for toluene combustion.

The progress of ferrites and ferrites-based nanocomposites has become extensively popular in the field of photocatalytic wastewater treatment. This class of compound exhibit several fascinating properties related with their high stability, low cost, ease of functionalization, and biocompatibility. Ferrites carry outstanding magnetic behavior that helps in their easy recovery from the aqueous system thus reducing the cost. The morphology and various properties such as magnetic, absorption, optoelectronic of magnetic ferrites can be varied and optimize by applying different synthetic routes and reaction conditions. With this background we have briefly presented and reviewed the latest development in the field of photodegradation of aqueous pollutants using ferrites based heterojunction. Especially, the type-II, Z-scheme and S-scheme based heterojunction for enhanced pollutant degradation under the exposure of light are thoroughly describe. Ferrites have inherent potential in water remediation applications hence many examples were consider to impart valuable knowledge to the readers. Nevertheless, the large-scale utilization of these magnetic nanoparticles still needs to be explored. Therefore, the gaps, challenges and future prospective of ferrites nanoparticles are also explained to unveil the un-scrutinized standard of ferrites nanoparticles.
