Enzymatic Production of Ecodiesel by Using a Commercial Lipase CALB, Immobilized by Physical Adsorption on Mesoporous Organosilica Materials
(MDPI, 2021)
The synthesis of two biocatalysts based on a commercial Candida antarctica lipase B, CALB enzyme (E), physically immobilized on two silica supports, was carried out. The first support was a periodic mesoporous organosilica ...
Biodiesel Is Dead: Long Life to Advanced Biofuels—A Comprehensive Critical Review
(MDPI, 2022)
Many countries are immersed in several strategies to reduce the carbon dioxide (CO2) emissions of internal combustion engines. One option is the substitution of these engines by electric and/or hydrogen engines. However, ...
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. ...
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 ...
Sulfonated organosilica-aluminum phosphates as useful catalysts for acid-catalyzed reactions: Insights into the effect of synthesis parameters on the final catalyst
(Elsevier, 2022)
The synthesis, by a sol-gel method, of organosilica-aluminum phosphates, (X)-AlPO(Y)-(Z), using three different silica precursors (X) 2-(4-chlorosulfonylphenyl)ethyltrimethoxysilane (C), 3-(mercaptopropyl)trimethoxysilane ...
