Modulating the electronic structure and pseudocapacitance of δ-MnO2 through transitional metal M (M = Fe, Co and Ni) doping

Ti‐Based Oxide Anode Materials for Advanced Electrochemical Energy Storage: Lithium/Sodium Ion Batteries and Hybrid Pseudocapacitors

“…The capacitors, mainly refer to EDLCs, often based on the ultra‐fast surface adsorption and desorption process, displaying sloping profiles line in the voltage‐capacity relation figure. In combination, the pseudocapacitance shows compositive characteristics and joint advantage of batteries and capacitors in the charge–discharge curves for satisfactory power and energy density …”

Tuning Overall Water Splitting on an Electrodeposited NiCoFeP Films

“…Third, tuning the electronic structure. Transition metal doping can form the intermediate bands and change the density of states in conduction band, thus efficiently unlocking the catalytic activity [22] . For instance, Sun and his team [23] found that the performance of Fe‐doped Ni 2 P nanosheet arrays toward overall water splitting depends strongly on the Fe doping ratio.…”

Experimental and Theoretical Investigation of the Effect of Oxygen Vacancies on the Electronic Structure and Pseudocapacitance of MnO2

“…Recently, numerous researchers have focused on MnO 2 ‐based composites or the doping of MnO 2 with metals (e.g., Al, Zn, Ce, Co and Fe) to improve their intrinsic conductivity . For example, Cakici et al.…”

“…Recently,n umerous researchers have focused on MnO 2based composites or the doping of MnO 2 with metals (e.g.,A l, Zn, Ce, Co and Fe) to improve their intrinsic conductivity. [23][24][25][26][27][28][29] For example, Cakici et al prepared ac arbon fiberf abric/corallike MnO 2 nanostructure by using ag reen hydrothermal method,w hich displayed ac apacitance of 467 Fg À1 at 1Ag À1 . [30] Zhou and co-workers reported Al-doped a-MnO 2 , which showed enhancede lectrochemical performance owing Defect engineering is an effective way to modulate the intrinsic physicochemical properties of materials.…”
