Cerium Doped NiO Nanoparticles: A Novel Electrode Material for High Performance Pseudocapacitor Applications

High Electrochemical Performance and Enhanced Electrocatalytic Behavior of a Hydrothermally Synthesized Highly Crystalline Heterostructure CeO2@NiO Nanocomposite

“…The composition of Ce 3+/4+ into Ni 2+/3+ to form heterostructure CeO 2 @NiO is well-known to enhance the electrochemical activity of the composites because of the synergetic effect of the different valence states . Recently, various working electrodes such as Ti foil, Ni foam, C-based electrodes, stainless steel, and conducting glass were used in supercapacitor studies. − …”

Cerium-doped β-Ni(OH)2 hexagon nanosheets: an effective photocatalyst for the degradation of the emerging water pollutant, naproxen

“…Cerium (Ce)-doped-Ni(OH) 2 has mostly been reported for pseudocapacitor applications [12], and Ce 3+ doping has been shown to improve the conductivity which enhances the electrochemical performance and cycling stability. Ce:NiO/rGO solgel nanostructures show enhanced electrochemical performance, which is believed to be due to the distortion of the crystal lattice caused by doping Ce into NiO [13].…”

Role of Cerium Doping in Petal‐Like NiO Grown Directly over Ni Foam for Enhancing the Super‐Capacitive Behaviour

“…Doping can be interstitial, substitutional or both, and can be isolated on the parent metal oxide‘s surface or absorbed into the lattice [15] . Modifying the electronic structures of nanoparticles using doping techniques has been widely used to induce new or improved catalytic, electro‐optical, magnetic, chemical, and physical property [16–17] in materials. For example, Li 3+ , Co 3+ , La 3+ , and Y 3+ can cause variations in the NiO stoichiometry and as a result, it is possible to regulate the concentration of Ni vacancies, which is significant for enhancing optical, magnetic, catalytic as well as electrochemical performance [18–20] .…”
