Electrocatalysis by design: Enhanced electro-oxidation of glycerol at NiOx nanoparticle modified 3D porous carbon felts

Recent developments in electrode materials for the selective upgrade of biomass-derived platform molecules into high-value-added chemicals and fuels

“…Therefore, the design of non-noble metal catalysts has been widely studied. 209,210 Ni-based electrocatalysts are attractive candidates for the GOR due to their relatively high electrocatalytic activity, toxicity resistance, and long-term stability in alkaline solutions. 208,[210][211][212][213][214][215] Baranova and Houache studied many Nibased electrode materials for the GOR in recent years.…”

In 2018, they investigated the GOR on polycrystalline Ni electrodes in alkaline media after sinusoidal-wave treatment.…”

Progress and challenges: Review for direct liquid fuel cell

“…They determine Ni(OH) 2 is converted to β‐NiOOH via proton diffusion mechanism and glucose is oxidized on the active surface of NiOOH and transformed to gluconolactone, methanoates, and oxalates. Meanwhile, a group of Ghaith and coworker 268 performed NiO x nanoparticles coated in 3D‐carbon fibers via electrodeposition method resulted in enhancement of glycerol electro‐oxidation when they do pretreatment of the commercial 3D‐carbon fibers in NaOH and H 2 SO 4 to functionalized with O‐and S‐ functionalities.…”

Tailor-designed binary Ni–Cu nano dendrites decorated 3D-carbon felts for efficient glycerol electrooxidation

“…Despite the aforementioned advantages of methanol fuel cells, they still suffer some drawbacks including high toxicity, high volatility, and poor stability of their commercial Pt-based electrodes, which is attributed to their rapid poisoning with in situ generated CO-like intermediates. 1–8…”

“…47 Besides, its electrochemical activity can be enhanced by several simple and fast methods (acid treatment, electrochemical treatment, plasma treatment, and thermal treatment). 4,48 Mohamed E. Ghaith et al 4 investigated the impact of electrooxidation of CF either in 1 M sulfuric acid or 1 M sodium hydroxide at different potentials on the performance of the electrodeposition of Ni particles towards glycerol electrooxidation. The pretreatments in either acidic or alkaline improved the catalytic activity of the electrodeposited Ni nanoparticles by 2.5 times compared to non-pretreated decorated carbon felt.…”
