Modulating the electrochemical capacitance of NiFe2O4 by an external magnetic field for energy storage application

Bypassing the scaling relationship with spin selectivity: construction of Lewis base-functionalized heterostructural 2D nanosheets for enhanced oxygen evolution reaction

“…Which results in exposing of more active sites over the surface of the catalyst with enriched coulombic effiency. 64 This improved electrocatalytic activity of Ni 3 S 4 @CoFe-LDH directly reects spin ordering in the presence of an external magnetic eld, followed by spin-selective oxygen evolution. Hence, the formation of a heterojunction altered the energetics of various intermediates, which offers an opportunity to break the scaling relationship.…”

Exploring the mechanisms of magnetic fields in supercapacitors: material classification, material nanostructures, and electrochemical properties

“…Besides, the magnetized electrodes themselves have excellent performance in terms of capacitance, reversibility, and load charge retention. For example, Silva et al 75 prepared NiFe 2 O 4 nanoparticles by the protein sol-gel method under a MF and tested their electrochemical properties. NiFe 2 O 4 was antiferromagnetic.…”
