On the role of the atmosphere in the catalytic glycerol transformation over iridium-based catalysts

Au/Pt/TiO2 catalysts prepared by redox method for the chemoselective 1,2-propanediol oxidation to lactic acid and an NMR spectroscopy approach for analyzing the product mixture

“…The high LA yield of 85-90% was obtained even at low temperatures of 250-290 • C [7]. The supported precious metals (Au, Ir, Pd, Pt, Rh, Ru) catalyzed the glycerol conversion in alkaline solutions under an inert or reducing atmosphere of 2-4 MPa and decreased the temperature of the glycerol conversion to 180-200 • C, but the LA yield was low [8][9][10][11].…”

The conversion of glycerol to lactic acid catalyzed by ZrO2-supported CuO catalysts

“…According to the experimental findings and the related literature data [21,23,31,35,45,46], a plausible reaction pathway for the conversion of glycerol to lactic acid as catalyzed by…”

Selective oxidation of glycerol over Pt supported on mesoporous carbon nitride in base-free aqueous solution

“…However, because of the complex nature of these reaction pathways, it is still a challenge to control the selectivity to give desired products. The aerobic oxidation of glycerol has been extensively studied by many groups using supported Pt [9,10], Pd [10,11], Au [10−22], Rh [23], Ir [24], and Cu-containing catalysts [25−28], and bimetals such as Pt-Bi [29], Au-Pd [30−33], Pd-Ag [34], and Au-Pt [35,36]. The activity and selectivity strongly depend on the reaction conditions (pH, temperature, and substrate to metal ratio) and the structure of the catalyst (metal, particle size, and support).…”
