Revealing the charge transfer mechanism and assessing product toxicity in the 2D/1D Bi₂O₂CO₃/Bi₈(CrO₄)O₁₁ heterostructure system

Abstract

With an improved charge separation efficiency, the heterojunction catalysts are widely used to enhance photocatalytic activity. However, the transfer mechanism of photoexcited charge carriers remains unclear and the researches about...

Montmorillonite helps BiOCl photodegradation of antibiotics

“…This, in turn, signified a stronger charge migration ability of the system. 38,39 1B/1M has the smallest EIS spectral arc radius (Fig. 4b) and the lowest PL intensity (Fig.…”

Applications of bismuth-based nanoparticles for the removal of pollutants in wastewater: a review

“…In this regard, Yang et al 162 conducted seed germination experiments on Bi-based NPs and the wastewater after degradation. The influence of the catalyst on seed germination was investigated, the results indicated that after seven days of cultivation, the germination rates of wheat seeds treated with 20% Bi 2 O 2 CO 3 /Bi 8 (CrO 4 )O 11 and those treated with H 2 O were approximately 96% and 94%, respectively, showing negligible differences.…”

Surface engineering of a 2D CuFe-LDH/MoS2 photocatalyst for improved hydrogen generation

“…Overall, the MoS 2 /CuFe-LDH hybrid has been considered a very efficient and stable photocatalyst for hydrogen production due to the synergetic effects of highly active CuFe-LDH and the sheet-like constitution of MoS 2 . 59,60 To gain further insights into the mechanism of photocatalytic H 2 generation and the separation of photogenerated electrons and holes in these MoS 2 /CuFe-LDH heterostructures, we also performed EIS, PL emission spectroscopy, and transient photocurrent measurements. In that, EIS analysis was employed to evaluate the internal resistance of the charge-transfer process of the samples.…”
