“…In addition of Ni(OH) 2 , the presence of NiO and Ni-NP also identified from the appearance of the UV-vis absorbance peak around 290 and 315 nm, respectively. [8,41,42] It is interesting to noticed that the peak corresponding to NiO and Ni-NP are significantly intense for the samples deposited at counter electrodes.…”

Nickel nanoparticle and graphene interfaces of various stoichiometries were created through electrodeposition techniques. The catalytic behavior of the electrodeposited films was investigated through spectro‐electrochemical methodologies. UV‐vis absorbance spectra of the electrodeposited films are significantly different in the air and alkaline medium. Furthermore, UV‐vis and Raman spectroscopy confirmed the coupling of Ni nanoparticles (Ni‐NP) with the graphene framework, along with NiO and Ni(OH)2. A combination of Raman and impedance spectroscopy revealed that the surface adsorption and charge transfer properties of the electrodeposited films are entirely dependent on the defects on graphene structure as well as distribution of Ni‐NP on graphene. The electrodeposited films possess heterogeneous catalytic properties with a low overpotential of 50 mV (10 mA/cm‐2) for hydrogen evolution reaction, as well as 601 mV and 391 mV (at 50 mA/cm‐2) for the oxygen evolution reaction and urea oxidation reaction, respectively. In addition, eelectrodeposited samples show extraordinary overall water splitting performance by achieving a current density of 10 mA/cm2 at a very small applied potential of 1.38 V. This synergistic coupling of Ni and graphene renders the electrodeposited samples promising candidates as electrodes for overall water splitting in alkaline and urea‐supplemented solutions.

“…In a rapid process assisted by microwave and polyol, nickel nanoparticles were synthesized and stabilized in an aqueous emulsion of copolymers. This approach involves reducing a metal salt (NiCl2•6H2O) in the presence of a low concentration of hydrazine hydrate with the assistance of a commercial copolymer (latex) acting as both the reducing and stabilizing agents [45]. Synthesis of nickel nanoparticles using nickel chloride in ethylene glycol and hydrazine as reducing agent [46] can be represented as:…”

This article presents a focused overview of advancements in the field of polyol synthesis of metal, metal oxide nanoparticles and nanocomposites, specifically those reported in the current decade. The aim of this article is to present the pertinent physico-chemical factors associated with nanoparticle synthesis in polyol solutions, highlighting their applications in both biological and industrial domains. The scope of this review article is selective rather than exhaustive, concentrating on noteworthy contributions to polyol nanoparticle synthesis that hold potential for refining synthesis methods. To comprehend the role of polyols in nanoparticle synthesis, an examination of the distinct physical properties of various polyols is crucial. Moreover, understanding the particular functions and mechanisms governing nanoparticle formation is imperative in this context.
