Olive Leaves as Biotemplates for Enhanced Solar-Light Harvesting by a Titania-Based Solid
(MDPI, 2020)
Olive leaves (by-product from olive oil production in olive mills) were used as biotemplates to synthesize a titania-based artificial olive leaf (AOL). Scanning electron microscopy (SEM) images of AOL showed the successful ...
Hydrogen Production through Glycerol Photoreforming on TiO2/Mesoporous Carbon: Influence of the Synthetic Method
(MDPI, 2020)
This article explores the effect of the synthetic method of titanium dioxide (TiO2)/C composites (physical mixture and the water-assisted/unassisted sol-gel method) on their photocatalytic activity for hydrogen production ...
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 ...
EPR and CV studies cast further light on the origin of the enhanced hydrogen production through glycerol photoreforming on CuO:TiO2 physical mixtures
(Elsevier, 2021)
Different CuO nanoparticles were synthesized and tested in CuO:TiO2 physical mixtures for hydrogen production through glycerol photoreforming. CuO alone was inactive whereas its presence in CuO:TiO2 mixtures significantly ...
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 ...
Glycerol photoreforming for photocatalytic hydrogen production on binary and ternary Pt-g-C3N4-TiO2 systems: a comparative study
(Elsevier, 2024)
Photocatalytic hydrogen production using two sacrificial agents (triethanolamine and glycerol) was conducted on several binary (Pt/TiO2 and Pt/g-C3N4) and ternary systems (Pt on a heterojunction between TiO2 and g-C3N4 ...
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 ...
Bio-Templating: An Emerging Synthetic Technique for Catalysts. A Review
(MDPI, 2021)
In the last few years, researchers have focused their attention on the synthesis of new catalyst structures based on or inspired by nature. Biotemplating involves the transfer of biological structures to inorganic materials ...
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 ...
