CoTe and CoTe2 nanorods with average diameter of 100 nm were synthesized by a simple hydrothermal process, and different CoTe2 nanostructures were obtained by changing the NaOH concentration. CoTe nanorods exhibit weak ferromagnetism while CoTe2 nanorods present paramagnetic behavior. Different magnetic behaviors occur in the other CoTe2 nanostructures due to Na+ entrance into CoTe2 crystals. A first-principles study on Na-doped CoTe2 confirms the magnetic characteristics.

The paper reports the synthesis of nickel tellurides via a mechanochemical method from elemental precursors. NiTe, NiTe2, and Ni2Te3 were prepared by milling in stainless steel vials under nitrogen, using milling times from 1 h to 12 h. The products were characterized by powder X-ray diffraction (pXRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM), energy-dispersive X-ray spectroscopy (EDX), dynamic light scattering (DLS), vibrating sample magnetometer (VSM), UV-VIS spectrometry, and thermal analysis (TGA and DSC). The products were obtained in the form of aggregates, several hundreds of nanometers in size, consisting of smaller nanosized crystallites. The magnetic measurements revealed a ferromagnetic behavior at room temperature. The band gap energies calculated using Tauc plots for NiTe, NiTe2, and Ni2Te3 were 3.59, 3.94, and 3.70 eV, respectively. The mechanochemical process has proved to be a simple and successful method for the preparation of binary nickel tellurides, avoiding the use of solvents, toxic precursors, and energy-consuming reaction conditions.

Nickel telluride nanorods (NiTe NRs) have been prepared by hydrothermal method using ascorbic acid as reducing agent and CTAB as surfactant and characterized by XRD, FE‐SEM, HR‐TEM and BET. EDX analysis confirms the formation of NiTe NRs. NiTe electrode material for supercapacitor is characterized by cyclic voltammetry (CV), galvanostatic charge‐discharge (GCD) and electrochemical impedance spectroscopy (EIS) measurements. A high specific capacitance of 618 F g−1 at the current density of 1 A g−1 and the cyclic stability with 75% of its specific capacitance retention after 5000 cycles are achieved. During the cyclic process, the coulombic efficiency is better than 99% indicating a good reversibility of NiTe electrode. The combination of high electrical conductivity, porous structure and the synergic effects of nickel play a significant role to obtain supercapacitor electrodes with excellent performances.
