Bismuth-based nanostructured photocatalysts for the remediation of antibiotics and organic dyes
Beilstein J. Nanotechnol. 2023, 14, 291–321, doi:10.3762/bjnano.14.26
- -scheme photocatalytic system. Li et al. [42] constructed spindle-shaped BiVO4-RGO-g-C3N4 Z-scheme photocatalysts for the highly effective degradation of antibiotics. The 1-D Z-scheme ternary nanocomposites had a very high photooxidation response. According to the authors, ciprofloxacin and tetracycline
Recent advances in nanoarchitectures of monocrystalline coordination polymers through confined assembly
Beilstein J. Nanotechnol. 2022, 13, 763–777, doi:10.3762/bjnano.13.67
- cubic, and CsCl structures were all available [134]. In particular, the 2D assembly showed significant activity regarding the photooxidation of mustard gas [134]. The specific site of the coordination polymer crystals could be modified to generate patchy colloids. By selectively growing a thin layer of
Ceria/polymer nanocontainers for high-performance encapsulation of fluorophores
Beilstein J. Nanotechnol. 2019, 10, 522–530, doi:10.3762/bjnano.10.53
- ) oxide nanoparticle layer, formed in situ at the surface of the hybrid nanocapsules, acts as oxygen scavenger and keeps external reactive molecular oxygen from entering into the capsules, eventually resulting in a reduction of the photooxidation of encapsulated fluorescent molecules. This approach shows
- , singlet oxygen is obtained through the process of fluorescence quenching [13][14][15][16]. Photooxidation significantly changes the emission properties of fluorophores because of an irreversible chemical reaction. In a simple description, the longer the fluorescence lifetime and the lower the fluorescence
- optical response of nanometric systems not only by quenching dramatically the fluorescence but also by photooxidation of the organic dye [21]. This effect is an additional source of uncertainty for quantitative measurements in life sciences [22][23]. Near-infrared (NIR) light undergoes less diffuse
Impact of the anodization time on the photocatalytic activity of TiO2 nanotubes
Beilstein J. Nanotechnol. 2018, 9, 2628–2643, doi:10.3762/bjnano.9.244
- photooxidation of methylene blue. Keywords: fluorine doping; nanotubes; photocatalytic activity; photoelectrochemistry; titanium(IV) oxide (TiO2); Introduction TiO2 started to attract great interest after Fujishima and Honda reported [1] on its photoelectrochemical (PEC) properties in 1972. Numerous features
Evaluating the toxicity of TiO2-based nanoparticles to Chinese hamster ovary cells and Escherichia coli: a complementary experimental and computational approach
Beilstein J. Nanotechnol. 2017, 8, 2171–2180, doi:10.3762/bjnano.8.216
- ]. Photocatalysis is an effective and environmentally friendly photooxidation process [2]. Development and application of photocatalysis techniques are reasonably economical endeavor. Photocatalysis could be a more reliable method than traditional methods for the inactivation of bacteria (i.e., UV disinfection and
The effect of surface charge on nonspecific uptake and cytotoxicity of CdSe/ZnS core/shell quantum dots
Beilstein J. Nanotechnol. 2015, 6, 281–292, doi:10.3762/bjnano.6.26
- increase the overall size of the nanoparticles, which may alter their uptake mechanism and limit some of their applications. Due to their complex structure and different potential sources of damage (e.g., air and photooxidation, opsonization and enzymatic degradation, mechanical damage, etc.), means for
Visible light photooxidative performance of a high-nuclearity molecular bismuth vanadium oxide cluster
Beilstein J. Nanotechnol. 2014, 5, 711–716, doi:10.3762/bjnano.5.83
- photooxidation is strongly dependent on the irradiation wavelength, with higher quantum efficiencies being observed at shorter wavelengths (Φ395nm ca. 15%). Recycling tests show that the compound can be employed as homogeneous photooxidation catalyst multiple times without loss of catalytic activity. High
- turnover numbers (TON ca. 1200) and turnover frequencies up to TOF ca. 3.44 min−1 are observed, illustrating the practical applicability of the cluster species.

- free drop-casting process. Core/shell NRs were chosen as they exhibit higher stability against photooxidation and chemical attack by radicals [2][9]. The band-gap within a type-I core/shell nanocrystal gradually increases from the inside to the outside [2][10]. In our first method, where radicals are
