Bio‐inspired NiO/ZrO2 mixed oxides (NZMO) for oxygen evolution reactions: from facile synthesis to electrochemical analysis

“…Metal oxide nanoparticles (NPs) have long been used in electrochemical applications, such as electrochemical sensors, energy conversion and energy storage, as a consequence of their superior electrochemical characteristics. Because of their redox characteristics and ease of large‐scale manufacturing, transition metal oxide nanoparticles (NPs) have garnered a lot of interest 22‐28 . Furthermore, the structural features of these NPs, such as size, morphology and crystallinity, are relatively straightforward to adjust, enabling systematic analysis of the structure–electrochemical property relation.…”

Influence of Co doping on phase, structure and electrochemical properties of hydrothermally obtained CoxZn1−xFe2O4 (x = 0.0–0.4) nanoparticles

“…In Fig. 10a, a pair of reversible redox or faradaic redox reaction peaks can be observed in every curve, indicating a pseudocapacitive behavior of these electrodes 1,5,15,19,42 . For the ZnFe 2 O 4 (x = 0) electrode, anodic and cathodic peaks appear at around 0.341 V and 0.184 V, respectively, which can be ascribed to stepwise oxidation and reduction of Zn 2+ and Fe 3+ /Fe 2+ in a KOH electrolyte, similar to earlier litera- The GCD results measured over a potential window 0-0.45 V at 1 A/g and various current densities of 1-10 A/g were used to determine the capacitive performance of Co x Zn 1−x Fe 2 O 4 (x = 0.0-0.4) NPs electrodes, as shown in Fig.…”

“…The chemical reactions between charges/ions in the electrolyte and electrodes materials are key functions that directly impact the performance of a SC cell. Practically, two important types of SCs are pseudo-capacitors (PCs) and electric double layer capacitors (EDLCs) 4,5 . Principally, each type of SC has similar cell structure, but a different charge storage mechanism and electrode material.…”

Research on the physical properties of LiMn0.5Fe2O4 spinel ferrites by the combination of optical, magnetic, and dielectric behaviors

“…Significant findings in this category of ceramics generally reveal excellent physicochemical properties, such as environmental benignity, 6 chemical stability, 7 high electrical resistivity, 8 and availability at low cost. 9 It is noteworthy to mention that a promising path has been paved for spinel ferrites to be useful for potential technological applications.…”
