“…From Figure 6A,B The comparison of NiCo 2 O 4 -rGO/Pt with other recently reported works and Pt/C for SOR in terms of current density and peak potential is presented in Figure 7. Catalysts of Pd/C, 29 Au@FS-rGO, 7 Pt/Ru Nanoparticles, 26 Pt/C, 27,53 Au-Pd/C, 28 Pt 10 Au 90 /C 27 were compared. Although the performance of NiCo 2 O 4 -rGO/ Pt is lower than Pt/C in 0.5 M sorbitol, 27 it is comparable with other works.…”

“…Catalysts of Pd/C, 29 Au@FS-rGO, 7 Pt/Ru Nanoparticles, 26 Pt/C, 27,53 Au-Pd/C, 28 Pt 10 Au 90 /C 27 were compared. Although the performance of NiCo 2 O 4 -rGO/ Pt is lower than Pt/C in 0.5 M sorbitol, 27 it is comparable with other works. As can be seen, the current density is better than more catalysts and peak potential is comparable with some works and higher than more reported works, representing that the synthesized catalyst has potential for sorbitol electrooxidation.…”

A ternary nanocatalyst consisting of nickel cobalt oxide (NiCo 2 O 4 ), reduced graphene oxide (rGO), and platinum (Pt) was introduced as a promising catalyst for application in the sorbitol oxidation reaction (SOR) process for use in fuel cells. Other catalysts such as NiCo 2 O 4 , NiCo 2 O 4 -rGO, and NiCo 2 O 4 /Pt were prepared for comparison. The structure and morphology of the synthesized nanocatalysts were examined by X-ray diffraction (XRD), scanning electron microscopy (SEM), and transmission electron microscopy (TEM). The efficiency of the as-synthesized materials was assessed by electrochemical tests of cyclic voltammetry (CV), linear sweep voltammetry (LSV), electrochemical impedance spectroscopy (EIS), and chronoamperometry (CA). The comparison of the SOR process for the synthesized nanocatalysts showed that NiCo 2 O 4 -rGO/Pt has the highest current density (57.2 mA cm À2 , 45.04 mA/mg) at a scan rate of 10 mV/s and the lowest peak potential (0.64 V) as well as the highest cyclic stability than other materials. The superior electrocatalytic performance is attributed to the synergistic effect of the components. Moreover, the charge transfer resistance of SOR for NiCo 2 O 4 -rGO/Pt catalyst is 702 Ω, lower than that for NiCo 2 O 4 /Pt (930 Ω). Thus, NiCo 2 O 4 -rGO/Pt constitutes an efficient and promising nanocatalyst for SOR.

Electro‐Synthesis of Organic Compounds with Heterogeneous Catalysis

et al. 2022

View full text Add to dashboard Cite

Electro-organic synthesis has attracted a lot of attention in pharmaceutical science, medicinal chemistry, and future industrial applications in energy storage and conversion. To date, there has not been a detailed review on electro-organic synthesis with the strategy of heterogeneous catalysis. In this review, the most recent advances in synthesizing value-added chemicals by heterogeneous catalysis are summarized. An overview of electrocatalytic oxidation and reduction processes as well as paired electrocatalysis is provided, and the anodic oxidation of alcohols (monohydric and polyhydric), aldehydes, and amines are discussed. This review also provides in-depth insight into the cathodic reduction of carboxylates, carbon dioxide, C=C, C≡C, and reductive coupling reactions. Moreover, the electrocatalytic paired electro-synthesis methods, including parallel paired, sequential divergent paired, and convergent paired electrolysis, are summarized. Additionally, the strategies developed to achieve high electrosynthesis efficiency and the associated challenges are also addressed. It is believed that electro-organic synthesis is a promising direction of organic electrochemistry, offering numerous opportunities to develop new organic reaction methods.
