Fabrication of NiO–carbon nanotube/sulfur composites for lithium-sulfur battery application

Abstract

The NiO–CNT/S composites combine the high conductivity of CNT and double adsorption of CNT and NiO (physical adsorption and chemical adsorption) to enhance electrochemical performance for sulfur electrode materials.

Facile synthesis of mesoporous nano Ni/NiO and its synergistic role as super adsorbent and photocatalyst under sunlight irradiation

“…Transition metal oxides are interesting materials with unique optical, magnetic, and electrical properties that make them a promising candidate for unlimited applications. One of these oxides is NiO, which was applied to many applications such as memory devices, gas sensors (Tong et al 2021 ), batteries (Jia et al 2021 ), light-emitting diodes and lighting devices (Taeño et al 2021b ; Zhang et al 2021 ), waveguides, and optical resonators (Taeño et al 2021a ). Due to its facile synthesis and stability, NiO was also examined as an adsorbent for a number of organic and inorganic pollutants such as dyes (Al-aoh 2018 ; Ramesh 2018 ), phenol (Dehmani and Abouarnadasse 2020 ), and heavy metals (Ziaeifar et al 2015 ; Adhikari et al 2017 ; Rajabi Kuyakhi and Tahmasebi Boldaji 2021 ).…”

Nanometer-thin ZrO2 Coating for NiO on MWCNTs as Anode for Improved Performance of Sodium-Ion Batteries

“…In the low-frequency region, a sloping straight line represents the Warburg impedance of sodium ion diffusion. 40 Owing to SEI film formation, the depressed semicircle can be observed in the high-frequency region. 46 These results specify that the presence of MWCNTs has facilitated the transport of sodium ions and improved electronic conductivity, which has further enhanced cycling performance while the ZrO 2 coating further improves the kinetics and lowers the impedance of the electrode.…”

Synergistic effect of adsorption and electrocatalysis of CoO/NiO heterostructure nanosheet assembled nanocages for high-performance lithium–sulfur batteries

“…65-2902) and NiO (JCPDS no. 89-7130), 55,56 further demonstrating that CoO/ NiO@C-NC is composed of both CoO and NiO crystals. The chemical properties of cobalt and nickel elements on the surface of CoO/NiO@C-NC and CoO@C-NC were further explored through XPS characterization.…”

“…3b). In addition, the two peaks at 856.6 and 854.7 eV in the Ni 2p 3/2 spectrum of CoO/NiO@C-NC represent the characteristic peaks of Ni 3+ and Ni 2+ , respectively 25,56 (Fig. 3c).…”
