Biochars from olive stones as Carbonaceous support in Pt/TiO2-Carbon Photocatalysts and application in hydrogen production from aqueous glycerol photoreforming
(MDPI, 2023)
Several biochars were synthesized from olive stones and used as supports for TiO2, as an active semiconductor, and Pt as a co-catalyst (Pt/TiO2-PyCF and Pt/TiO2-AC). A third carbon-supported photocatalyst was prepared from ...
Controlled photodeposition of Pt onto TiO2-g-C3N4 systems for photocatalytic hydrogen production
(Elsevier, 2022)
Platinum (0.5 wt. %) was photodeposited on g-C3N4-TiO2 systems using UV or Vis light. Different absorption by semiconductors seemed to somehow influence resulting platinum particle size and distribution. Thus, lower platinum ...
Fourth generation synthesis of solketal by glycerol acetalization with acetone: A solar-light photocatalytic approach
(Elsevier, 2021)
Background: Biomass is the only renewable alternative to fossil fuels to produce chemicals. In this sense, glycerol is an important biomass-derived platform chemical obtained as a by-product during biodiesel generation. ...
Synthesis of Fe-TiO2 and Cu-TiO2 Based Materials by Olive Leaves Biotemplating—Application to Hydrogen Production from Glycerol Photoreforming
(MDPI, 2023)
Hydrogen production is mainly based on the use of fossil fuels, but currently, many alternative routes are being developed, among which the photo-reforming of oxygenated organic compounds stands out. Recently, several ...
Influence of sacrificial agent on Cu photodeposition over TiO2/MCH composites for photocatalytic hydrogen production
(Elsevier, 2022)
Titanium (ca. 11 wt%) was dispersed on a carbonaceous mesoporous support and modified with copper (ca. 5 wt%) photodeposited using either glycerol or methanol as the sacrificial agent ((Cu-TiO2/MCH_(Gly) and Cu-TiO2/MCH_(Met) ...
Pt Preferential incorporation onto TiO2 IN TiO2-carbon composites for hydrogen production from glycerol photoreforming
(Elsevier, 2022)
Platinum was incorporated onto titania-mesoporous carbon composite and tested for glycerol photoreforming. The relative high surface area of the mesoporous carbon favored the good dispersion of anatase titania during sol-gel ...
Hydrogen photo-production from glycerol on platinum, gold and silver-modified TiO2-USY62 catalysts
(Elsevier, 2022)
In this work, photocatalysts consisting of TiO2 supported on zeolite (USY62) were synthesized by sol-gel method and, subsequently, a noble metal (Pt, Au, or Ag) was incorporated by impregnation or photodeposition. Zeolite-TiO2 ...
