TiO2-In-MIL-101(Cr) with Visible Light-Induced Peroxidase Activity for Colorimetric Detection of Blood Glucose

“…Compared with MIL-101(Cr), the light absorption of TiO 2 -in-MIL-101(Cr) increases at 300−500 nm, which is favorable for the visible light-induced catalysis. The band gap energy (E g ) was calculated through the Tauc plot 15…”

“…Compared with MIL-101(Cr), the light absorption of TiO 2 -in-MIL-101(Cr) increases at 300–500 nm, which is favorable for the visible light-induced catalysis. The band gap energy ( E g ) was calculated through the Tauc plot 15 where α is the absorption coefficient near the absorption edge, h is Planck’s constant, ν is light frequency, n depends on the light transition form of semiconductor materials, and A is the slope of the Tauc plot in the linear region. Figure 2 C exhibits that the E g of TiO 2 -in-MIL-101(Cr) is much lower than that of MIL-101(Cr), which is beneficial to the visible light-induced catalytic process.…”

UV-Vis Spectroscopy, Electrochemical and DFT Study of Tris(β-diketonato)iron(III) Complexes with Application in DSSC: Role of Aromatic Thienyl Groups

“…Comparing the UV-Vis of complexes 1-9, it is clear that λ A,max,exp becomes red-shifted as more aromatic groups are attached to the β-diketonato ligands in the [Fe(β-diketonato) 3 ] complexes 1-9. The introduction of one Ph or two Ph side groups per β-diketonato ligand successively causes a redshift of ~30 nm: Fe(acac) 3 (1) (270 nm) → [Fe(ba) 3 ] (3) (298 nm) → [Fe(dbm) 3 ] (7) (336 nm) Fe(tfaa) 3 (2) The absorbance maxima of the complex with six thienyl groups is the most redshifted. Complexes 1-9 can thus be grouped into three groups according to the influence of aromatic groups on the wavelength of the maximum absorbance λA,max,exp, in the 250-400 nm region:…”

“…Tris(β-diketonato)iron(III) complexes represent an important class of organometallic compounds, which have been used in modern applications by many researchers in recent years. Some of the modern application areas where these compounds are used include photocatalysis [1], redox mediators in solar cells [2], energy storage (batteries) [3][4][5], catalysts, pre-catalysts and reagents in organic chemistry [6][7][8][9].…”

Extending the visible light absorption of NH2-UiO-66 through diazotization reaction for photocatalytic chromium (VI) reduction

“…To nd out the changes in band gap energies, Tauc equation (αh ) 1/n =B(h -E g ) was employed in which α, h, , B and E g refers to absorption coe cient, Plank constant, light frequency, a constant, and band gap energy, respectively (Makuła et al 2018). Also, n represents for the electronic transition type, which is assumed to be 1/2 for direct allowed transitions (Chen et al 2019, Hosseini et al 2022). According to the Tauc plots depicted in Fig.…”
