Structural studies of NiTe2 thin films with the influence of amino additives

Abstract

Background: Nickel, one of the transition metals synthesised with chalcogenides such as Se, S and Te with possible combinations of nickel chalcogenides such as NiS 2 , NiSe, NiSe 2 and Ni 3 Se 2 . The combination of nickel and telluride are the fewest being observed due to the nature of tellurium that is relatively heavier than both sulphur and selenium, thus poorly-adhesive onto the substrate. Methods: Therefore, NiTe 2 thin film is being synthesised onto the indium tin oxide (ITO) coated glass substrates with the complex additives (Triethanolamine, TEA and ethylenediaminetetraacetic acid, EDTA) and their properties are studied. The present work is focusing on the NiTe 2 synthesise through electrochemical route. Results: Cyclic voltammetry experiments have been done prior to electrodeposition in order to get the electrodeposition potential range. The observable reduction range is between −0.9−(−1.1) V with 5−10 min induction period of full thin film distribution depending upon the electrolyte conditions.

Effect of heat input and weld chemistry on mechanical and microstructural aspects of double side welded austenitic stainless steel 321 grade using tungsten inert gas arc welding process

“…The double side-tungsten inert gas weldments show lowest absorbed energy 119.0 J compared to base metal 123.17 J. This is because of the existence of higher induced δ-ferrite in the weld metal [31,32]. The samples could not entirely break in the notched area.…”

Rational Design of Metallic NiTex (x = 1 or 2) as Bifunctional Electrocatalysts for Efficient Urea Conversion

“…Elsewhere, nickel sulfides and nickel selenides were most investigated by researches . Another analogue of nickel tellurides, which profits from the metallic feature of tellurium, is of fundamental interest in their own right but also for their potential technological relevance. − Considerable recent research related to transition metal telluride, including CoTe 2 , NiTe 2 , MnTe 2 , NiTe, and CoTe, have been performed in electrocatalysis applications. − As concluded previously, both transition metal monotellurides and ditellurides are capable to electrocatalysis in alkaline solution. However, more sophisticated design and controllable synthesis of monotellurides and ditellurides are required in experiment, especially for developing improved bifunctional electrocatalysts.…”

NiTe Nanorods as Electrode Material for High Performance Supercapacitor Applications

“…Anand et al . have found that the acidic electrolyte is not suitable for depositing NiTe 2 thin film through electrochemical route . The present work deals with the fabrication of NiTe NRs by hydrothermal process for supercapacitor applications.…”

“…[26] Magnetic phase transition in NiTe x from paramagnetic (x = 1) to diamagnetic (x = 2) has been reported by Lie et al [27] Anand et al have found that the acidic electrolyte is not suitable for depositing NiTe 2 thin film through electrochemical route. [28] The present work deals with the fabrication of NiTe NRs by hydrothermal process for supercapacitor applications. NiTe NRs exhibit a high specific capacitance of 618 F g À 1 and 1 A g À 1 current density with an outstanding cyclic stability of 75% of initial specific capacitance after 5000 cycles at a high current density of 10 A g À 1 .…”
