Rhodamine B dye is efficiently degraded by polypropylene-based cerium wet catalytic materials

Abstract

Polypropylene non-woven fabric grafted with polyacrylic acid enriched with cerium ions was used for the degradation of RhB.

Hydrothermal synthesis of PVP-passivated clove bud-derived carbon dots for antioxidant, catalysis, and cellular imaging applications

“…The specific rate constant of PPCCDs was calculated to be 7.39 s -1 g -1 . The specific rate constant k and apparent rate constant k app of PPCCDs was found to be superior when compared with some other reported catalysts shown in Table S3 [45][46][47][48][49]. The presence of The CDs due to their small size and high surface-to-volume ratio could be projected as an effective substrate for dye degradation.…”

Hydrothermal Synthesis of Clove Bud-Derived Multifunctional Carbon Dots Passivated with PVP- Antioxidant, Catalysis, and Cellular Imaging Applications

“…The specific rate constant of PPCCDs was calculated to be 7.39 s -1 g -1 . The specific rate constant k and apparent rate constant k app of PPCCDs was found to be superior when compared with some other reported catalysts shown in Table S3 [46][47][48][49][50]. The presence of The CDs due to their small size and high surface-to-volume ratio could be projected as an effective substrate for dye degradation.…”

The Release Potential of Microplastics from Face Masks into the Aquatic Environment

“…Sustainability 2023, 15, x FOR PEER REVIEW 6 of 15 masks were examined, it could be clearly seen that all layers of both masks were made of polypropylene, corresponding to the characteristic adsorption bands at 2950, 2916, 2870, 2837, 1456, 1375, 1166, 996, 973, 840 and 808 cm −1 [36,37]. Four broad peaks in the wavenumber ranging from 2800 to 3000 cm −1 were evident, corresponding to CH2 and CH3 vibrations.…”

“…Four broad peaks in the wavenumber ranging from 2800 to 3000 cm −1 were evident, corresponding to CH 2 and CH 3 vibrations. More specifically, the peaks at 2916 and 2837 cm −1 corresponded to the asymmetric and symmetric -C-CH 2 -C-stretching vibrations, while the peaks at 2950 and 2870 cm −1 were due to -C-CH 3 stretching vibrations [37,38]. The peaks at 1456 and 1375 cm −1 were attributed to -CH 3 , -CH 2 -bending vibrations, while the peaks at 1166 cm −1 were due to -(CH 2 )n-bending vibrations [37].…”

The peaks at 1456 and 1375 cm −1 were attributed to -CH3, -CH2-bending vibrations, while the peaks at 1166 cm −1 were due to -(CH2)nbending vibrations [37]. Lastly, small peaks in the spectrum are characteristic of polypropylene, including C-C stretching and CH3 asymmetric rocking at 996 cm −1 and 973 cm −1 , C-H rocking at 840 cm −1 and C-C stretching at 808 cm −1 [36].…”
