“…Here, it can be observed that the nickel had a good distribution on the electrode surface and formed particle clusters; however, the iron presented smaller amounts of particles. Figure 3A shows the EGP/RGO/NiOOH electrode in the absence and presence of 10 mmol L −1 of ethanol; in voltammetry cyclic (VC), the electrode showed an oxidation peak close to the potential of 0.60 V. The results that can be Ni (III)/Ni (II) redox can catalyze an ethanol electrooxidation [12][13][14]. As can be seen in Figure 3B, the EGP/RGO/FeOOH electrode did not show an oxidation peak for ethanol.…”

In this work, nickel (Ni) and Ni-Fe bimetallic microparticles were electrosynthesized at reduction potentials in the range from −0.70 V to −1.20 V (50 mV s−1) by cyclic voltammetry (CV) onto graphite/paraffin electrode surface modified with nanosheets of reduced graphene oxide (RGO). Previously, the RGO was electrodeposited by CV from a suspension of 1 mg mL−1 of graphene oxide in PBS solution with pH 9.18, in the potential range from −1.50 V to 0.50 V (10 mV s−1). After electrodeposition of metals, the oxyhydroxides were formed by CV in an alkaline medium of 0.10 mol L−1 of NaOH in the potential range from −0.20 V to 1.0 V (100 mV s−1) with successive scans until stabilization of currents. In order to characterize the developed electrodes composites, the surfaces were investigated by scanning electron microscopy (SEM) and energy-dispersive X-ray spectroscopy (EDX). Electrochemical performance of the developed electrodes composites to ethanol electrooxidation was carried out in an alkaline medium of 0.10 mol L−1 of NaOH in the potential range from −0.20 V to 1.0 V (100 mV s−1) by CV. The electrodes were able to induce the electrooxidation of ethanol at a potential of 0.55 V for the electrode made of NiOOH/FeOOH and around of 0.60 V for the electrode modified with NiOOH.

“…Non-precious metal-based electrocatalysts become popular in recent years as the promising alternatives in this area, especially Ni-based materials. [96][97][98] In fact, HMF oxidation, MOR and EOR, are essentially nucleophilic oxidation reactions (NORs) with active hydrogen presence as the functional groups (such as hydroxyl and aldehyde). Many researchers argue that NiOOH is the active site in Ni-based materials for those NORs.…”

Direct glycerol fuel cell (DGFCs) is an interesting type of fuel cell that can produce energy and high-end chemicals using excess and less expensive fuel, glycerol. The commercialization of DGFCs meets with many challenges, especially on its catalyst development. Common catalysts usually tested in DGFCs are platinum-based (Pt) and palladium-based catalyst (Pd). The expensive value of the noble metal such as Pt and Pd becomes a limitation towards the commercialization. This review shows and summarizes numerous improvements achieved on the anode catalyst for GOR to reduce the noble metal dependency while maximizing the activity performance, durability-stability, and GOR yield selectivity on certain valuable chemicals introducing multiple optimized syntheses methods with timesaving and cost-effective benefits. Finally, this review proposes the next direction of catalyst development to be taken in the future based on the recent developments and innovations implemented and tested.
