“…Recently, many chalcogenides selenides such as Ni, Co, Fe and Mo selenides have been reported to date. Metal selenides are typically prepared by using chemical bath deposition 12 , chemical vapor deposition 13 , electrodeposition 14 , simple chemical synthesis 15 , and hydrothermal techniques 16 . Among these, hydrothermal techniques are shown to generate metal selenides of varying structure and high crystallinity 17 .…”

We report a simple hydrothermal method used for the synthesis of Cr2Se3 hexagons (h-Cr2Se3) and its application towards electrochemical sensing of 4-nitrophenol (4-NP). The formation of h-Cr2Se3 was confirmed by using scanning electron microscopy, energy dispersive X-ray spectroscopy, X-ray diffraction, and X-ray photoelectron spectroscopy. The electrochemical activity of the h-Cr2Se3 modified screen-printed carbon electrode (SPCE) towards 4-NP was studied using cyclic voltammetry (CV) and amperometric i-t techniques. Typically, the obtained results were compared with those for a bare SPCE. The CV result clearly reveals that h-Cr2Se3 modified SPCE has higher catalytic activity towards reduction of 4-NP than bare SPCE. Hence, h-Cr2Se3 modified SPCE was concluded as a viable sensor for sensitive determination of 4-NP. Under optimized conditions, h-Cr2Se3 modified SPCE demonstrates the excellent capacity to detect the 4-NP in a linear range from 0.05 µM to 908.0 µM. The LOD and sensitivity in detection of 4-NP were determined at 0.01 µM and 1.24 µAµM−1 cm−2 respectively. The sensor is highly selective and stable and shows reproducible recovery of 4-NP in domestic supply and river water samples.

Ionic liquid zinc chloride-1-ethyl-3-methylimidazolium chloride (IL ZnCl 2 -EMICl) with a ZnCl 2 /EMICl ratio of 40/60 mol% was used as the electrolyte to study the voltammetric behavior of Se(IV) introduced into the IL as selenium chloride (SeCl 4 ) or selenium oxide (SeO 2 ). The electrodeposition of ZnSe was performed using constant-potential electrolysis at tungsten electrodes via a two-stage approach from the IL with and without SeO 2 . The nucleation mechanism of Se at the tungsten electrodes agrees better with the three-dimensional instantaneous nucleation than the progressive nucleation based on Sharifker's model. Crystalline Se and approximately stoichiometric crystalline ZnSe electrodeposits could be obtained from this system. The ZnSe films showed photoelectrochemical activity with a bandgap energy of ∼2.5 eV. According to the experiments of the dependence of the photocurrent on the applied potential, the ZnSe film was determined to be a p-type semiconductor with the flatband potential V FB of −0. Zinc selenide (ZnSe) is a II-VI semiconductor that belongs to the chalcogenide family. ZnSe is usually obtained as a n-type semiconductor with a wide bandgap (2.67-2.7 eV). p-type ZnSe, which is very likely due to excess Se in the deposits, has been prepared using electrodeposition.1 ZnSe has been reported to be a useful material for various optoelectronic devices, such as lightemitting devices, window layers for solar cells, photovoltaic cells, laser screens, film transistors, photoelectrochemical cells, and optical components for infrared lasers. 19,25 Compared with these approaches, electrodeposition is more attractive [26][27][28][29] in terms of convenience, cost, and suitability for the large-scale production of thin films. Moreover, the surface morphology, composition, and properties of semiconductors can be flexibly controlled by adjusting the operating parameters such as electrodeposition potential or current, potential waveforms (constant potential or pulse potential), concentration of precursors, temperature, and additives. Therefore, ZnSe has been widely prepared using electrodeposition, with mostly successful results. Most electrodepositions of ZnSe were carried out cathodically in acidic aqueous baths containing Zn(II) and SeO 2 . [30][31][32][33][34][35][36][37] In acidic solutions, SeO 2 dissolves to form H 2 SeO 3 . ZnSe has also been electrodeposited from alkaline aqueous baths. [38][39][40] In alkaline solutions, Zn(II) and SeSO 3 2− are most frequently used as the precursors, and complexing agents, such as EDTA, are usually needed for forming strong complex ions with Zn 2+ to prevent the chemical precipitation of ZnSe, which is produced from the reaction between Zn(II) and SeSO 3 2− . Few studies have electrodeposited ZnSe from nonaqueous baths such as dimethylsulfoxide [41][42][43] and molten salts (CaCl 2 -NaCl at 550• C). 44,45 In almost all recent studies and applications of ZnSe semiconductors, ZnSe has been prepared using electrodeposition from aqueous baths.

“…The acid solution is more studied by different authors using ITO [22], Cu [23], Ti [23] and porous Si [24] substrates. Many authors observed that ZnSe crystalline films with Se excess are obtained and that stoichiometry for the Zn:Se ratio can be achieved after annealing treatment [5,25] .…”
