Nickel–vanadium monolayer double hydroxide for efficient electrochemical water oxidation
Highly active and low-cost electrocatalysts for water oxidation are required due to the demands on sustainable solar fuels; however, developing highly efficient catalysts to meet industrial requirements remains a challenge. Herein, we report a monolayer of nickel-vanadium-layered double hydroxide that shows a current density of 27 mA cm(-2) (57 mA cm(-2) after ohmic-drop correction) at an overp...
متن کاملNi3+ doped monolayer layered double hydroxide nanosheets as efficient electrodes for supercapacitors.
Ni(3+) doped NiTi layered double hydroxide (NiTi-LDH) monolayer nanosheets with a particle size of ∼ 20 nm and a thickness of ∼ 0.9 nm have been successfully prepared through a facile bottom-up approach. These NiTi-LDH monolayer nanosheets exhibit excellent supercapacitor performance, including a high specific pseudocapacitance (2310 F g(-1) at 1.5 A g(-1)) and long durability compared with bul...
متن کاملLarge-scale synthesis of highly dispersed layered double hydroxide powders containing delaminated single layer nanosheets.
A facile method for the synthesis of Zn2Al-borate and Mg3Al-borate layered double hydroxides (LDHs) with extremely high specific surface areas of 458.6 and 263 m(2) g(-1) and containing delaminated nanosheets is reported. To the best of our knowledge, this is the first report of LDH powders that still remain exfoliated on drying.
متن کاملAn advanced Ni-Fe layered double hydroxide electrocatalyst for water oxidation.
Highly active, durable, and cost-effective electrocatalysts for water oxidation to evolve oxygen gas hold a key to a range of renewable energy solutions, including water-splitting and rechargeable metal-air batteries. Here, we report the synthesis of ultrathin nickel-iron layered double hydroxide (NiFe-LDH) nanoplates on mildly oxidized multiwalled carbon nanotubes (CNTs). Incorporation of Fe i...
متن کاملA high-performance reduced graphene oxide/ZnCo layered double hydroxide electrocatalyst for efficient water oxidation.
Tailoring high performance, stable, and earth-abundant electrocatalysts for water oxidation is of fundamental importance for the development of promising energy conversion and storage technologies. In this work, we report a remarkably simple and efficient approach for the preparation of ZnCo-layered double hydroxides and reduced graphene oxide (RGO/ZnCo-LDH) nanocomposites via a facile one-pot ...
