Regulating the Oxygen Vacancy and Electronic Structure of NiCo Layered Double Hydroxides by Molybdenum Doping for High‐Power Hybrid Supercapacitors

“…Compared with most previously reported LDH-based materials listed in Table 1, MoNiCo-LDH-0.05/CC has a better energystorage capability. [7,9,13,31,46,[49][50][51][52][53][54] In order to deep investigate the influencing factors for the superb electrochemical performance of the electrode materials, the electrochemical active surface areas (ECSA) of MoNiCo-LDH-0.05/CC and NiCo-LDH/CC are compared. The ECSA is assessed by measuring the electric double layer capacitance (C dl ) .…”

“…Benefiting from the high exposure area, short ion transport channel, and good conductive substrate, the NiCo-LDH nanosheets grown on g-C 3 N 4 with a flower-like morphology displayed high and stable capacitive performances. [13] In addition, carbon cloth (CC) as a common conductive substrate has also been widely used in the preparation of supercapacitor electrodes. Devi et al pointed out that CC had a self-supporting 3D conductive network, good flexibility, and large surface area, on which the supported nanocomposite electrodes presented excellent electrochemical efficiencies.…”

“…In a word, the excellent energy storage performance of MoNiCo-LDH-0.05/CC is contributed by the close anchoring of MoNiCo-LDH cross-linked network nanosheets on CC substrate, facile adsorption of OHions and rapid charge transfer in the electrochemical reaction process. Compared with most previously reported LDH-based materials listed in Table1, MoNiCo-LDH-0.05/CC has a better energystorage capability [7,9,13,31,46,[49][50][51][52][53][54].

Construction of NiCo-LDH/g-C3N4 heterojunctions as efficient photocatalysts for enhanced degradation of tetracycline hydrochloride and hydrogen evolution

“…18 LDHs can act as electrocatalysts and capacitors due to the higher current density and lower overpotential. 19,20 In addition, LDHs with tunable metal cation composition and facile exchange ability of interlaminar anions allows electronic structure tuning, making them a promising catalyst. 21,22 For example, Megala et al designed a NiAl-LDH/g-C 3 N 4 /Ag 3 PO 4 dual direct Z-scheme photocatalyst with enhanced catalytic activity.…”
