Studies on the interaction of interface between morin and TiO2

Morin Flavonoid Adsorbed on Mesoporous Silica, a Novel Antioxidant Nanomaterial

“…As the antioxidant activity of morin did not decrease when is adsorbed onto the nanoparticles, this may indicate that the resorcinol moiety in B-ring, which is the most reactive site in the molecule against free radicals, is able to interact with hydroxyl radicals. For quercetin, which is structurally similar to morin by replacing the resorcinol in B-ring to a 3’,4’-cathecol moiety, when adsorbed onto silica NP, it has been documented a similar behavior against superoxide radical [93], indicating that the B-ring is free to react with the free radicals and that the linkage of this flavonoids to the NP takes place through the polar groups in A and C-rings [59, 94]. The antioxidant capacity against hydroxyl radical is summarized in Fig 9.…”

Fotocatálisis para la Producción de Combustibles Solares

“…El TiO 2 es un semiconductor tipo n, el cual, es posible obtener a temperaturas relativamente bajas (menor a 550 °C), y que ha logrado ser utilizado a nivel comercial debido a que presenta una actividad fotocatalítica superior gracias a que posee una mayor área superficial y una mayor cantidad de sitios activos para la adsorción para la catálisis [9], [10] .…”

Tunable physics through coordination chemistry: formation on oxide surface of Ti and Al chelates with 3-hydroxyflavone capable of electron injection and light emission

“…Indeed, a literature search only results in a few studies on their specific use as photosensitizers, especially in solar cells [14][15][16][17][18][19] and photocatalysts, 20 and it has been reported that morin (a 3HF derivative) can bind TiO 2 nanoparticles (NPs). 21,22 Self-assembled monolayers (SAMs) are spontaneously adsorbed and ordered monolayers of molecules on planar and nonplanar substrates, generating just one molecule thick films. The interest in SAMs emerged with the aim of creating a hetero-interface, whose properties can be finely tuned and whose utility has been demonstrated in a broad range of fields.…”
