Does Bridging Geometry Influence Interfacial Electron Transfer Dynamics? Case of the Enediol-TiO₂ System

Influence of TIO2-rGO optical properties on the photocatalytic activity and efficiency to photodegrade an emerging pollutant

“…GO and rGO yielded an A D /A G value close to 1.1, indicating a disordered structure even after GO was reduced by the hydrothermal treatment [24,59], whereas values around 1.33 were estimated for the P25-rGO nanocomposites. The increase of the ratio is the result of the strong interaction between TiO 2 and rGO sheets after the hydrothermal method, plus the contribution of remaining surface oxygenated functional groups [24,56,60,61].…”

Promising sensitizers for dye sensitized solar cells: A comparison of Ru(II) with other earth's scarce and abundant metal polypyridine complexes

“…The longer excited state lifetimes for the dyes with the abundant metal ions V 3+ and Cr 2+ furthermore facilitate the charge transfer. In this article, we have selected the excited states according to the Frank‐Condon approach as has been done in many previous studies . However, considering the subsequent excited state relaxation for all the different systems is computationally very demanding.…”

“…In this article, we have calculated different properties of the tris bipyridine complex with different scarce and abundant metal ions coupled to well‐known anchoring groups used for DSSCs (Scheme ) . Four of them (the first four in Scheme ) have been used for the Ru‐bipyridine dye for NiO p‐SC by Pellegrin et al First of all, we considered structural properties such as the interaction energy of the metal ions with the dye and the change of dihedral angles upon interaction with the various metal ions and different anchors.…”

Visible light driven photocatalysis mediated via ligand-to-metal charge transfer (LMCT): an alternative approach to solar activation of titania

“…The other spectroscopic characterizations of the catechol complex have been carried out by transient absorption spectroscopy, 54,62 uorescence quenching, [63][64][65] Raman spectroscopy 55 and electron paramagnetic resonance. Other phenolic compounds that were reported to form the LMCT complexes include resorcinol and quinol, 59 pyrogallol and gallic acid, 67 salicylic acid, 58 4-chlorophenol, 2,4-dichlorophenol, 2,4,6-trichlorophenol, 2,4,5-trichlorophenol, 68-70 dopamine, 50,51,58,71 alizarin, methylcatechol and t-butylcatechol, 50 fullerol, 72 sulfocalixarene, 73 calixarene, 74 1,1binaphthalene-2,2-diol, 75 C 11 -resorcinarene 76 and 8-hydroxyquinoline. 30 The substituting groups attached on the benzene ring (e.g., -Cl, -NH 2 , -OH, -COOH, -CH 3 , and -C(CH 3 ) 3 ) vary in their electron donating (or withdrawing) properties and sensitively inuence the optical absorption and charge transfer efficiency.…”
