Photocatalytic generation of H2O2 over a Z-scheme Fe2O3@C@1T/2H-MoS2 heterostructured catalyst for high-performance Fenton reaction

Abstract: The wide application of the Fenton reaction has been severely restricted by the requirement of continuous feeding of H2O2, the iron-slurry production, and the slow recycle rate of Fe3+/Fe2+. This...

“…The morphology, structure, and crystalline phase remained the same in the reused sample, indicating the superior stability of the catalyst. 67 Similarly, another research group demonstrated that H 2 O 2 produced on MoS 2 /FeS 2 achieved effective in situ Fenton TC degradation. 66 TC degradation efficiency decreased to 76.9% after five cycles of reuse.…”

“…The continuous release of Fe was identified as the primary reason for this degradation in performance. 45 In another research, Fe 2 O 3 @C@1T/2H-MoS 2 photocatalyst was investigated by Yang et al 67 Nearly 83.6% degradation efficiency was achieved after the fifth cycle of TC degradation, suggesting effective recyclability. An inductively coupled plasma mass spectroscopy (ICP-MS) analysis of the fresh and the recycled sample showed that the decrease in activity was mainly because of the leaching and dissolution of Fe ions in the reaction medium (0.285 mgL −1 ).…”

“…In contrast to the classic type-II heterojunctions, bio-inspired Z-scheme heterojunctions not only enhance light harvesting features and the spatial dispersion of charge carriers but also maintain the elevated redox potentials of photo-induced h + and e − , which is crucial for H 2 O 2 generation. 32,37 In this context, 1T/2H-MoS 2 @BCN synthesized via hydrothermal strategy was applied towards TCH degradation and H 2 evolution (290 μmol h −1 ) in our previously reported work. Although it gives fascinating results, MgIn 2 S 4 @1T/2H-MoS 2 is designed to further promote the photocatalytic activity of 1T/2H-MoS 2 .…”

“…Generally, the Fenton-like reaction requires a large amount of H 2 O 2 as a substrate, while the organism does not generate enough H 2 O 2 to supply it, which needs the addition of exogenous H 2 O 2 or the production of H 2 O 2 through relevant reactions. 18,19 In the bacterial infection microenvironment, the levels of antioxidant glutathione (GSH) are abnormally high, and the overexpressed GSH can deplete ROS, leading to a significant decrease in the function of nanozymes. 20 Our team has successfully developed Cu 2 O-demethyleneberberine nanospheres serving as a self-cascading platform, which can exhibit GSH-oxidase (OXD)-like activity to obtain H 2 O 2 through oxidative consumption of GSH for the purpose of continuous supply of H 2 O 2 for the Fenton-like reaction, and then H 2 O 2 is transformed into ˙OH, without the introduction of exogenous H 2 O 2 .…”
