“…438 About 85% glycerol conversion and 57% selectivity to glycolic acid were achieved over a 3.6 wt% Ag loaded catalyst. Díaz et al 439 440 Mainly, the 5% Pt containing Ag95-Pt5/CeO 2 catalyst showed the best performance with 54% glycerol conversion and 51% glycolic acid selectivity. Interestingly, further increase of the Pt amount (up to 50%) led to a noticeable shift in product selectivity from glycolic acid to glyceric acid.…”

“…Zaid et al investigated the ceria-supported silver-based catalysts promoted by noble metal (Au, Pd or Pt) for GLY oxidation with molecular oxygen at NaOH/GLY ratio of 4/1 mol/mol [151]. GlyA was the main oxidation product, and the catalyst selectivity was not affected by the nature of promoter ( Table 6).…”

Ag-Based Catalysts in Heterogeneous Selective Oxidation of Alcohols: A Review

et al. 2018

View full text Add to dashboard Cite

Alcohols (bioalcohols) is a class of chemicals that are used as a feedstock for the manufacturing of a large number of valuable intermediates in industrially important processes. Currently, sustainable technologies for selective conversion of alcohols utilize “green” oxidants, mainly, ambient air or oxygen. Due to the high affinity of oxygen towards silver, the latter serves as an active component of supported heterogeneous catalysts. In this review, we consider Ag-based catalysts that participate in gas- or liquid-phase oxidation of alcohols. Oxidation of methanol, ethanol, ethylene glycol, propylene glycol, glycerol, benzyl and allyl alcohols is mostly considered. A particular attention is paid to selective photooxidation of alcohols over Ag-based catalysts. We discuss the catalyst composition in terms of (1) the state of the active component, (2) the nature of the substrate, (3) support nature, and (4) the strength of the metal–support interactions.

“…The glycerol partial oxidation in the liquid phase can lead to various products such as aldehydes (glyceraldehyde), ketones (dihydroxyacetone), and carboxylic acids (glyceric acid, tartronic acid, glycolic acid, etc.) (Katryniok et al, 2011; Mimura et al, 2014; Skrzynska et al, 2016, 2019; Zaid et al, 2017).…”

Glycerol valorization through partial oxidation is a good way of obtaining many different molecules with high added value such as glyceric acid, tartronic acid, dihydroxyacetone, etc. Among the potential products, glyceraldehyde is an interesting chemical compound for its various applications in different domains such as organic chemistry, medical, and cosmetic industries. In the present paper, we studied the effect of different supports on the glycerol oxidation reaction in a batch reactor applying base-free conditions. The tested catalysts were Pt-based materials deposited on various supports (i.e., SiO 2 , TiO 2 , ZSM-5, γ-Al 2 O 3 ), which were synthesized using a deposition method followed by a chemical reduction. The catalysts were extensively characterized (BET, ICP, XRD, TEM, XPS), highlighting differences in terms of specific surface areas, textural properties, and Pt nanoparticles sizes. We evidenced a direct relation between glycerol conversion and glyceraldehyde selectivity (i.e., an increase in glycerol conversion leads to a decrease in glyceraldehyde selectivity). The Pt/γ-Al 2 O 3 catalysts exhibited the highest activity, but their selectivity to glyceraldehyde significantly decreased with time on stream. Pt/SiO 2 presented the highest selectivity to glyceraldehyde owing to a slower reaction rate, which allows envisioning technical opportunities to continuously extract the formed glyceraldehyde from the mixture.
