Preparation of 3D rose-like nickel oxide nanoparticles by electrodeposition method and application in gas sensors

2D metal oxide nanoflakes for sensing applications: Review and perspective

“…The most common architectures are flower-like structures as shown in Fig. 2c-d [20,21], in which the nanoflakes form a highly porous sphere and are oriented perpendicular to the sphere surface, i.e. emanating from the core.…”

“…Coordination polymer precursors provide an easy route to multicomponent mixed metal oxides with high composition uniformity [69,70]. Electrodeposition has been reported as a method to prepare Ni flowers that can subsequently be oxidized to NiO [21,71]. ZnO nanoforests and TiO 2 nanowalls have been obtained by oxidation of corresponding metal films [72,73].…”

Influence of Pamoic Acid as a Complexing Agent in the Thermal Preparation of NiO Nanoparticles: Application to Electrochemical Water Oxidation

“…Over the past two decades, bulk and nanoscale nickel oxide (NiO) have attracted attention for their high stability, nontoxicity,, and anomalous chemical, electrochemical,, electronic,,, magnetic,,, and catalytic,,, and optical,,, properties. NiO nanoparticles (NiONPs), in particular, are used in a variety of fields as electrochemical sensors, biosensors,, electrochromic windows, gas sensors,, super capacitor, batteries, fuel cells,, photovoltaic cell, electrochemical water splitting,, catalysis,,, and photocatalysis . The broad applicability of nanoscale NiO relies on the material's high surface area and interesting properties, including chemical, electrochemical, and catalytic properties, which are not present in the bulk material.…”

“…The broad applicability of nanoscale NiO relies on the material's high surface area and interesting properties, including chemical, electrochemical, and catalytic properties, which are not present in the bulk material. To meet the high demand for this nanoscale material, several synthetic methods have been developed based on hydrothermal,,,, sol‐gel,,, hot‐injection, co‐precipitation, microwave,, reverse micelle templated, electrochemical and pulsed laser ablation techniques, as well as techniques based on complex formation with an organic moieties and successively their thermal decomposition . Among the mentioned methods, the latest one is well known as scalable with high yield.…”
