Phase-Pure High-Entropy Spinel Oxide (Ni,Fe,Mn,Cu,Zn)3O4 via Thermal Plasma: A Promising Electrocatalyst for Oxygen Evolution Reaction

“…36,37 Kumaresan et al used the thermal plasma method to produce single-phase ferromagnetic iron nitride nanoparticles for oxygen evolution and supercapacitor applications. 38 Ko et al used a non-transferred DC thermal plasma method to produce boron nitride nanoparticles from boron oxide and melamine as a feedstock material. 39 Tharchanaa et al synthesized Cu and CuO nanoparticles from copper scrap using the thermal arc discharge method and then tested their antimicrobial activity.…”

“…The results show that the as-synthesized nanoparticles have good antimicrobial activity. 40 Many metal oxides, including single metal oxide, 38 bimetal oxide, 41 and multimetal oxide 42 nanopowders are prepared in the thermal plasma route by continuous thermal evaporation of a feedstock material followed by condensation. Till date, highentropy metal oxide nanoparticles with a single phase have not been prepared via the thermal plasma method.…”

“…This method is a continuous process that involves evaporation, nucleation, and condensation. Thermal plasma has recently been used to synthesize metal, metal oxides, metal borides, metal nitrides, and metal alloy nanoparticles for a variety of applications. , Kumaresan et al used the thermal plasma method to produce single-phase ferromagnetic iron nitride nanoparticles for oxygen evolution and supercapacitor applications . Ko et al used a non-transferred DC thermal plasma method to produce boron nitride nanoparticles from boron oxide and melamine as a feedstock material .…”

Fabrication of carbon-coated chromium nitride (CrN@C) and chromium oxynitride (CrON) nanoparticles by a thermal plasma technique for supercapacitor applications

“…It is also observed that as the operating current increases, the synthesized nanoparticles exhibit larger crystallite sizes. 33,35 Fig. 2(b) shows the XRD patterns of the synthesized nanoparticles in a nitrogen atmosphere; from this XRD pattern, the mixed-phase crystal structures were obtained such as CrN and Cr 2 O 3 .…”

“…In the TPAD method, the plasma arc can easily persist at temperatures above 10 000 K, they attach directly to the anode, which works as a work-piece (conducting materials). [33][34][35] This method has numerous advantages such as fast, clean and dry processes, which is better than the chemical methods involving multiple steps and a long-time nitridation process. However, the TPAD technique is a short-time high-temperature process, where the work-piece involves immediate melting, evaporation, nucleation and condensation.…”
