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 ...
Simple and eco-friendly thermal regeneration of granular activated carbon from the odour control system of a full-scale WWTP: Study of the process in oxidizing atmosphere
(Elsevier, 2021)
Adsorption by granular activated carbon (GAC) is an efficient, reliable, and well-established technique for treating malodours in wastewater treatment plants (WWTPs). However, when the lifespan of GAC is over, it becomes ...
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 ...
Hydrogen photoproduction on TiO2-CuO artificial olive leaves
(Elsevier, 2021)
Olive leaves were used as biotemplates to synthesize diverse TiO2-CuO solids. A successful replication of trichomes and internal channels was evidenced by SEM, whereas a good dispersion of Cu and Ti atoms was observed by ...
The NtrYX Two-Component System of Paracoccus denitrificans Is Required for the Maintenance of Cellular Iron Homeostasis and for a Complete Denitrification under Iron-Limited Conditions
(MDPI, 2022)
Denitrification consists of the sequential reduction of nitrate to nitrite, nitric oxide, nitrous oxide, and dinitrogen. Nitrous oxide escapes to the atmosphere, depending on copper availability and other environmental ...
Recent Advances in the Use of Covalent Organic Frameworks as Heterogenous Photocatalysts in Organic Synthesis
(Wiley, 2022)
Organic photochemistry is intensely developed in the 1980s, in which the nature of excited electronic states and the energy and electron transfer processes are thoroughly studied and finally well-understood. This knowledge ...
A Continuous flow approach for the desulfurative bromination of sulfides
(Elsevier, 2024)
The preparation of alkyl bromides is a pivotal transformation in organic chemistry. The wide range of applications that bromides have as building blocks render this class of compounds a privileged motif widely used in the ...
Preparation of graphene-based nanomaterials by pulsed RF discharges on liquid organic compounds
(IOP Publishing, 2020)
A new pulsed RF plasma reactor has been used for the synthesis of graphene-based nanomaterials under atmopheric pressure conditions. This is an environmental-friendly system, not using catalyst and where no hazardous ...
