Influence of co-existing alcohol on charge transfer of H2 evolution under visible light with dye-sensitized nanocrystalline TiO2

Preparation of Mn-doped ZrO2/TiO2 photocatalysts for efficient degradation of Rhodamine B

“…[14][15][16][17][18] Zirconium dioxide (ZrO 2 ) is an inexpensive, stable, non-toxic, wide bandgap oxide semiconductor (E g ≈ 5.0 eV), and has appropriate flat-band potentials for photocatalytic purposes. [19][20][21][22] In previous studies, TiO 2 coupled with zirconia has been investigated extensively in degradation of organic compounds.…”

Strategies to improve electrochemical performances of pristine metal‐organic frameworks‐based electrodes for lithium/sodium‐ion batteries

“…Porphyrins are a class of aromatic organics with π‐conjugated planar structures, which have been widely used in photocatalysis and pollutant degradation 92–95 . In recent years, the synthesized porphyrin‐based MOF materials have received extensive attention due to their large specific surface area and excellent stability 96–98 .…”

The pH-depending enhancement of electron transfer by {001} facet-dominating TiO2 nanoparticles for photocatalytic H2 evolution under visible irradiation

“…A controlled experiment with a D 2 O solution proved that the origin of the evolved hydrogen was confirmed to be from protons in water not from other compounds, such as the donor species or dye-sensitizers. [25][26][27] Another controlled experiment without the dye-sensitizer also ensured that the residual UV light in the filtered light is negligible for H 2 evolution.…”

“…23,24 We recently reported that the electron injection process of the dye-sensitization system strongly depends on the co-existing species, methanol (MeOH) and triethanolamine (TEOA), as the sacrificial electron donors in the surrounding solution for the photocatalytic H 2 evolution. [25][26][27] According to the previous studies, the efficiency of the photo-excited electron injection significantly degraded due to the adsorption-desorption nature of the co-existing species, MeOH, in the case where the porphyrine dye-sensitizer, tetrakis(4-carboxyphenyl) porphyrine (TCPP) on TiO 2 nanoparticles was used as the photocatalyst for H 2 evolution in an aqueous MeOH solution, while same TCPP/TiO 2 exhibited almost complete injection in the TEOA solution.…”
