“…The P25 photocatalyst exhibited 95% degradation over 120 min of visible light irradiation ( Figure 10 ). The commercial P25 photocatalyst was able to highly decompose the dye solution and break its molecular bonding thanks to high photo-response, adsorption, and charge separation activities [ 58 , 59 , 60 , 61 ]. The biosynthesized CoFe 2 O 4 nanoparticles achieved nearly equal results to the degradation ability of the commercial P25 photocatalysts.…”

Biogenic CoFe2O4 nanoparticles were prepared by co-precipitation and Hibiscus rosa sinensis plant leaf was used as a bio-reductant of the nanoparticle productions. The biosynthesized CoFe2O4 nanoparticles were characterized by XRD, FTIR, UV, VSM, and SEM via EDX analysis. The cubic phase of biosynthesized CoFe2O4 nanoparticles and their crystallite size was determined by XRD. The Co-Fe-O bonding and cation displacement was confirmed by FTIR spectroscopy. The presence of spherically-shaped biosynthesized CoFe2O4 nanoparticles and their material were confirmed by SEM and TEM via EDX. The super-paramagnetic behaviour of the biosynthesized CoFe2O4 nanoparticles and magnetic pulse was established by VSM analysis. Organic and bacterial pollutants were eradicated using the biosynthesized CoFe2O4 nanoparticles. The spinel ferrite biosynthesized CoFe2O4 nanoparticles generate radical and superoxide ions, which degrade toxic organic and bacterial pollutants in the environment.

“…In the indirect Z-scheme heterojunction, the strong redox capacity of photocatalysts remains after the recombination of the electrons and holes of weaker redox capacity through an intermediate conductor (Figure d). Currently, precious metals such as Pt and Pd are often used as intermediate conductors in all-solid-state indirect Z-scheme heterojunctions, but their widespread application is restricted because of high cost. Recently, Wan’s group fabricated a S-vacancy-rich ZnIn 2 S 4 /carbon nanotubes/nanosized red phosphorus (ZIS-S/CNTs/NRP) all-solid-state indirect Z-scheme heterojunction where CNTs acted as an intermediate conductor.…”

Semiconductor photocatalysis has demonstrated a promising potential in solving the energy crisis and environmental pollution. In the past few years, hexagonal ZnIn 2 S 4 has received increasing attention in photocatalysis due to its relatively narrow band gap, strong reducing power for hydrogen evolution reaction (HER), excellent chemical stability, nontoxicity, as well as low cost. This Review summarizes the latest advances of ZnIn 2 S 4 -based photocatalysts for the conversion of solar energy to hydrogen production, accompanied by selective organic oxidation to obtain value-added chemicals and organic pollute degradation. First, the basic crystal structure, photoelectric properties, and preparation methods of ZnIn 2 S 4 are briefly introduced. Three typical kinds of modification strategies including defect engineering, cocatalyst loading, and heterojunction fabrication then are summarized. As for the photocatalytic activity, besides the conventional HER in the presence of hole capturers, we have highlighted the developments of ZnIn 2 S 4 -based photocatalysts for H 2 production via overall water splitting, and H 2 production coupled with selective oxidization of organics and with degradation of organic pollutes. Last, some challenges that ZnIn 2 S 4 would face to realize application in solar energy conversion and environmental protection are presented.
