Highly efficient Pt/TiO2Pt/TiO2 photocatalyst for hydrogen generation prepared by a cold plasma method

Enhanced Hydrogen Production from Methanol/Water Photo-Splitting in TiO2Including Pd Component

“…In order to overcome this rapid recombination in water splitting, studies aimed at improving the level of hydrogen production via methanol or ethanol photodecomposition, not water, have focused on modified (Ag or Cu) TiO2, [7][8][9][10] which can be used to activate the photo catalysts, using UV light with longer wavelengths and noble metal (Pt, Rh) doped TiO 2 , [11][12][13] which has relatively high activity and chemical stability under UV irradiation. In particular, Zou 11 and Ikuma 12 reported that the activity for hydrogen generation from water/alcohols is greatly improved on Pt/TiO2, synthesized using a cold plasma method with the highest rate of H2 production being obtained from Pt-deposited TiO 2 formed by the formaldehyde method.…”

“…In particular, Zou 11 and Ikuma 12 reported that the activity for hydrogen generation from water/alcohols is greatly improved on Pt/TiO2, synthesized using a cold plasma method with the highest rate of H2 production being obtained from Pt-deposited TiO 2 formed by the formaldehyde method. Idriss 13 compared the level of hydrogen production from ethanol photo-splitting between Pt, and Rh/TiO2, where the addition of Pt increased the level of hydrogen production significantly with a quantum yield of approximately 10% at 350 K. On the other hand, Rh-doped TiO2 is far less active.…”

Hydrogen Production from Photo Splitting of Water Using the Ga-incorporated TiO2s Prepared by a Solvothermal Method and Their Characteristics

“…To overcome this rapid recombination in water splitting, more investigations into the production of hydrogen via methanol or ethanol photodecompositions to upgrade hydrogen production, not water, have focused on modified (Ag or Cu)-doped TiO 2,[8][9][10][11] which can be used to activate the photocatalysts, using UV light with longer wavelengths and noble metal (Pd, Pt, Rh)-doped TiO2, [12][13][14] which have relatively high activity and chemical stability under UV irradiation. The new materials, Ag-TiO 2 and Cu-TiO 2 , where Ag x O and Cu x O were substituted into a TiO2 framework, were investigated as conducting components to reduce the large band gap of pure TiO 2 .…”

“…As a result, the Ag and Cu components were found to be very useful for the production of H 2 gas in a methanol photodecomposition system; the productions reached 17,000 µmol and 16,000 µmol after 24 h over Ag/TiO 2 and Cu/TiO 2 , respectively. Zou and Ikuma have reported that the activity for hydrogen generation from water/alcohols is greatly improved on Pt/TiO 2 , synthesized by a cold plasma method, 12 and the highest rate of H 2 production was also obtained from the Pt-deposited TiO2 that was formed by the formaldehyde method, 13 respectively. Particularly, Idriss 14 compared the hydrogen production from photo-splitting of ethanol between Pd, Pt, and Rh/TiO2s.…”

Conservation methods of iron artifacts recovered from the marine environment

“…The plasma method includes impregnation, treatment, calcinations and reduction (Zou et al, 2007). Filament cathode low pressure gas discharges are used as ion sources for plasma chemistry.…”
