First Assessments of the Influence of Oxygen Reduction on the Glycerol Electrooxidation Reaction on Pt

Borohydride Reduction Method for PdIn/C Electrocatalysts Synthesis towards Glycerol Electrooxidation under Alkaline Condition

“…Chino et al [8] highlighted that the advantages of using DGFCs are that under alkaline conditions, a less corrosive environment is possible to be achieved as well as to use non-metallic nanoparticles. In agreement with Nascimento et al [9], the scientific community has studied metallic nanoparticle synthesis and their use as active and selective catalysts for glycerol reactions in alkaline conditions, so it is essential to focus on the study of glycerol reactions aiming energy and products selective purposes.…”

An Overview of Glycerol Electrooxidation Mechanisms on Pt, Pd and Au

“…This proposition is usually developed into a reaction mechanism that attributes the production of C1/C2 products to the electrooxidation of C2/C3 intermediates (Figure 7). [17,30,36,64] A cautious verification of Proposition B requires two aspects: (1) showing that these C3/C2 intermediates have a relatively higher probability to be further oxidized than glycerol, and (2) how CO 2 /formate/C2 intermediates are produced at high overpotentials in Stage II and Stage III.…”

“…Recent GEOR studies have proposed many reaction pathways and mechanisms, contributed by, among others, the groups of Koper, [30,33,34] Coutanceau, [55,74,137] Fernández [37,38,42,134] and Martins [17,84,138] . Soluble intermediates and products are well established by experiment, but evidence for surface‐adsorbed intermediates comes mainly from DFT studies.…”

“…Nickel used to be utilized synergistically with noble metals, [4–6] but, its high activity of electro‐catalyzing GEOR alone has made it a promising substitute for noble metals [7–9] . With metallic electrocatalysts offering high efficiency in GEOR, studies conducted by researchers worldwide have covered all aspects related to GEOR, including novel nanocatalysts enhancing the efficiency and selectivity of GEOR towards certain products, [10–12] product distribution analysis for the determination of the reaction mechanisms and kinetics, [13,14] and fuel cell fabrications (theoretically generating 1.01 V), [15–17] as shown in Figure 2c. Among them, the selectivity of glycerol oxidation products (usually reported with HPLC or FTIR data as illustrated in Figure 2d) is of great interest as it directly influences the potential for commercial production of value‐added products.…”
