Fabrication of SnSO4-modified TiO2 for enhance degradation performance of methyl orange (MO) and antibacterial activity

Green Biosynthesis of Tin Oxide Nanomaterials Mediated by Agro-Waste Cotton Boll Peel Extracts for the Remediation of Environmental Pollutant Dyes

“…However, the degradation of MO dye does not change significantly without a catalyst; only 9.56% degrades under UV light irradiation, as represented in Figure 9 D. Similarly, the degradation of MO in the case of sample SNPs-5 is around 8.69%, as illustrated in Figure 9 E. In contrast, for sample SNPs-8, the 10.43% degradation occurs within 100 min, as shown in Figure 9 F. Our results are pretty similar to those reported by Yao et al (2021), which report MO dye degradation 91.3% after 14 h in the presence of visible light irradiation. 43 Hence, the above III determined well the % of MO dye degradation and the effectiveness of the photocatalytic treatment process. The obtained results of photodegradation of MB and MO were compared with the degradation time and the % of degradation reported literature (see Table 2 ).…”

Programmable biological state-switching photoelectric nanosheets for the treatment of infected wounds

“…Thus, we propose that bioactive nanomaterials with strong photoelectric responses may be ideal alternatives, as they are generally not only noninvasive but also capable of producing electrical stimulation using light irradiation as an external stimulus. Although traditional photoelectric materials, like TiO 2 , have been used for antibacterial study, their low light absorption properties and low electron-hole separation efficiency limit their practical application [ 25 ]. In this work, highly responsive photoelectric BiOCl nanosheets are developed for on-demand photoelectron switching between polarization states to treat infected tissue defect repair.…”

Au-Au/IrO2@Cu(PABA) Reactor with Tandem Enzyme-Mimicking Catalytic Activity for Organic Dye Degradation and Antibacterial Application

“…Methylene blue will generate intermediate products like benzenesulfonic acid, diphenyl sulfoxide, azure B, etc . Also, rhodamine B will yield degradation products such as phthalic acid, adipic acid, 3-hydroxybenzoic acid, etc . However, it can be found from Figure a–c and the results of other literature reports − that the UV absorption peak types and positions of these three dyes do not change significantly with the extension of the degradation time.…”
