Abstract

The present study reports trigonal phase molybdenum disulfide quantum dots (MoS2/QDs)-decorated (Bi1−xFex)VO4 composite heterostructures.

Pt/PtOx Nanoparticle-Decorated BiVO4 Pinelike Structure for Enhanced Sulfamethoxazole Mineralization under Visible Light Irradiation

“…For Bi 4f (Figure b), two strong peaks located at around 159.4 and 164.7 eV correspond to Bi 4f 7/2 and Bi 4f 5/2 , with the splitting of 5.3 eV. These two peaks are characteristic peaks of Bi 3+ ion in BiVO 4 crystal. , The V 2p spectra exhibit two strong peaks at around 524.2 and 516.5 eV (Figure c) that are indexed to V 2p 1/2 and V 2p 3/2 , respectively. These signals can be indexed to V 5+ ions in the BiVO 4 crystal. , We also observed that the positions of Bi 3+ and V 5+ in Pt/PtO x /BiVO 4 composites had a slightly shifted toward higher binding energy, indicating the interaction between Pt/PtO x NPs and BiVO 4 . , The deconvolution analysis of the O 1s peak suggests the presence of two distinct oxygen species.…”

Experimental and theoretical study of catalytic dye degradation and bactericidal potential of multiple phase Bi and MoS2 doped SnO2 quantum dots

“…57,58 MoS 2 enhanced the catalytic activity as it helped to transfer electrons (electron capture) as compared to the control sample. 59 The defects as well as disorders ascribed to the Bi 3+ , act as the trapping center for e − /h + pairs, and effectively hinder the photo-generated charge carriers recombination. 60 Antibacterial activity of undoped and MoS 2 -doped SnO 2 and Bi (1 and 3%)/MoS 2 -doped SnO 2 QDs is encapsulated in the Table 1.…”

2D Heterostructures Induced Charge Transfer and Trapping for Hybrid Optically and Electrically Controllable Nonvolatile Memory

“…Its chemical formula, MX 2 , signifies the presence of transition metal (M) and sulfur element (X). [26][27][28][29][30] It possesses low toxicity, high mobility, the characteristic of the optical, and high stability. In multi-layer structures, it exhibits semiconductor properties with an indirect bandgap.…”
