Selective Catalytic Oxidation of Glycerol to Dihydroxyacetone

Carbon supported Pt9Sn1 nanoparticles as an efficient nanocatalyst for glycerol oxidation

“…As mentioned earlier, the supported SnO 2 alone is totally inactive for oxidation of glycerol. It suggests that a balance between surface Pt and SnO species is critical for higher activity of glycerol oxidation, as SnO may assist in deprotonation of hydroxyl group and Pt is responsible for abstraction of beta hydrogen from the adsorbed glycerol [16,37]. Furthermore, the average particle size of Pt 0.8 Sn 1 nanoparticles is around 3.2 nm (Fig.…”

“…It is to be noted that the supported SnO 2 /C is totally inactive for glycerol oxidation. It was reported that both alpha and beta hydrogen abstraction could contribute to the rate determining step [37]. Noble metals are generally believed to be responsible for deprotonation of beta hydrogen.…”

Glycerol

“…The mechanism involves reversible palladium alkoxide formation with the oxidation of palladium as the turnover-limiting step. 10 (B) A regio-and chemoselective reduction of nitroarenes and carbonyl compounds over recyclable magnetic ferrite nickel nanoparticles (Fe 3 O 4 -Ni) was achieved by using glycerol as the hydrogen source. The catalyst was reused eight times without any significant loss in catalytic activity and selectivity.…”

Ethyl lactate from dihydroxyacetone by a montmorillonite-supported Pt(II) diphosphane complex

“…Alternative synthetic protocols for EtLA use glycerol [2], C 6 [3,4] and C 3 -sugars, such as glyceraldehyde or dihydroxyacetone (DHA) [5][6][7][8][9][10][11][12] as starting material. DHA is a convenient starting compound, since it is obtained by either fermentation of glycerol [13] or selective metal-based glycerol oxidation reactions [14][15][16][17][18][19]. Homogeneous metal salt-based catalytic reactions employed for the DHA to alkyl lactate conversion occurred only at a high metal concentration (ca.…”
