“…The high metallic property of selenium makes selenides possess higher electrical conductivities compared to oxides and sulphides. Nickel, a 3d transition metal, is much cheaper and less toxic compared to cadmium and other transition group metals [27,28]. Nickel and selenium form different homogenous and crystalline phases such as NiSe 2 , Ni 1-x Se, and Ni 3 Se 2, although other compounds are known to exist.…”

Quantum dots (QDs) are semiconducting materials with diameters ranging from 2-10 nm. Amongst these QDs, nickel selenide quantum dot (NiSeQD) materials have gained much interest from researchers over the past few years due to their outstanding properties. These include excellent catalytic activity, good electrical conductivity for charge transfer, and excellent thermodynamic stability. NiSeQD material is relatively cheap, less toxic, and can be synthesised easily. Due to the fascinating and remarkable properties of NiSeQD, the material has been applied in various electrochemical fields, including hydrogen evolution reaction (HER), oxygen evolution reaction (OER), and solar cells. This review focuses on the application of NiSeQD and its composites in the various analytical fields in the search for alternative renewable sources of energy. Interestingly, NiSeQD material can be modified with different materials to improve its sensitivity, reactivity, and limit of detection. The effects of modification with other materials such as iron (Fe), cobalt (Co), and graphene (GN) are mentioned. Additionally, the application of NiSeQD in glucose sensing is discussed briefly. In these aforementioned applications, NiSeQD has shown excellent electrocatalytic capability with satisfactory detection limits and good conductivity. Thus, further exploration of it to other fields is essential. This review highlights the importance of NiSeQD in water purification, and no report has been documented in the literature on its application in water purification. Some gaps are still open for the use of NiSeQD material as an electroactive platform for sensing devices in water treatment.

“…For example, hexagonal selenium has high photoconductivity ( e . g ., 8 × 10 4 S cm −1 ) (Chen et al, 2009 ), a low melting point (217°C) (Chen et al, 2009 ), non-linear optical properties due to its anisotropic crystal structure (Steichen and Dale, 2011 ), high piezoelectricity (

)(Mayers et al, 2003 ), catalytic activity toward organic hydration and oxidation reactions (Xiong et al, 2006 ), and high reactivity leading to so many functional materials including Ag 2 Se (Tian et al, 2017 ), CdSe (Jeong et al, 2005 ; Sobhani and Salavati-Niasari, 2014 ), ZnSe (Zhang et al, 2016 ), PbSe (Salavati-Niasari et al, 2013 ), SnSe (Zhao et al, 2014 ), and NiSe (Salavati-Niasari and Sobhani, 2013 ; Hussain and Hussain, 2019 ). Such properties make Se a promising candidate for applications in photocells, photographic exposure meters, solar cells, semiconducting rectifiers, xerographic copying machines (Zhu and Hu, 2004 ), gas sensors (Norio and Tsukio, 2011 ) and Li-Se batteries (Gu et al, 2018 ).…”

Selenium, depending on its crystal structure, can exhibit various properties and, as a result, be used in a wide range of applications. However, its exploitation has been limited due to the lack of understanding of its complex growth mechanism. In this work, template-free electrodeposition has been utilized for the first time to synthesize hexagonal-selenium (t-Se) microstructures of various morphologies at 80°C. Cyclic voltammetry (CV) and linear sweep voltammetry (LSV) revealed 5 reduction peaks, which were correlated with possible electrochemical or chemical reaction related to the formation of selenium. Potentiostatic electrodeposition using 100 mM SeO 2 showed selenium nanorods formed at−0.389 V then increased in diameter up to −0.490 V, while more negative potentials (-0.594 V) induced formation of sub-micron wires with average diameter of 708 ± 116 nm. Submicron tubes of average diameter 744 ± 130 nm were deposited at −0.696 V. Finally, a mixture of tubes, wires, and particles was observed at more cathodic potential due to a combination of nucleation, growth, dissolution of structures as well as formation of amorphous selenium via comproportionation reaction. Texture coefficient as a function of applied potential described the preferred orientation of the sub-microstructures changed from (100) direction to more randomly oriented as more cathodic potentials were applied. Lower selenium precursor concentration lead to formation of nanowires only with smaller average diameters (124 ± 42 nm using 1 mM, 153 ± 46 nm using 10 mM SeO 2 at −0.389 V). Time-dependent electrodeposition using 100 mM selenium precursor at −0.696 V explained selenium was formed first as amorphous, on top of which nucleation continued to form rods and wires, followed by preferential dissolution of the wire core to form tubes.

The progressive lifestyle and technologically driven economic growth have considerably increased the energy demand across the globe. This has stressed the existing energy resources and adversely affected the environment. To address increased energy demands, it is indispensable to go for a clean carbon-neutral energy source and highly efficient energy storage solutions. Among the different energy storage systems, supercapacitors (SCs) are promising due to their ultrahigh power densities, higher coulombic efficiencies, stable cycling performances, cost-effectiveness, and environment-friendliness. [1][2][3][4] However, their lower energy densities compared to other electrochemical energy technologies like batteries and fuel cells, limit their further applications. Different strategies have been employed for improving the electrochemical properties of SC and an encouraging outlook is to assemble hybrid supercapacitors (HSCs). It consists of two distinct electrodes working via Faradaic, pseudocapacitive, and electric double-layer capacitive (EDLC) charge storage mechanisms. The electrochemistry of two electrode materials in one SC device offers a synergy of high energy storage capacity (Faradaic materials, also known as batterytype materials) and high rate (non-Faradaic materials). However, due to a significant mismatch in the charge dynamics between non-Faradaic and battery-type electrodes, these devices frequently fail to achieve their expected performance. To solve this issue, a double hybridization perspective is envisaged wherein one electrode is EDLC type while the other should be EDLC/battery-type or pseudocapacitor hybrid electrode. [2,5,6] The choice of electrode material thus becomes critical for high-performing energy storage devices. The other factors that are crucial in electrochemical properties are structure, morphology, and composition. Nanostructurization of such electrode materials leads to atomic/molecular level interaction, decreased diffusion pathways, stability in phase changes, etc., and offers improved electrochemical activity. Transition metal selenides have recently attracted much attention over sulfides due to their high electrical conductivity, interesting chemical behavior, and formation of variety of stable selenides such as nickel selenides (NiSe) in terms of stoichiometric and nonstoichiometric compounds. [1] The small difference in electronegativity between Ni (1.9 eV) and Se (2.4 eV), valence electronic configuration of Ni
