Hierarchical Hollow Nanoprisms Based on Ultrathin Ni‐Fe Layered Double Hydroxide Nanosheets with Enhanced Electrocatalytic Activity towards Oxygen Evolution

Abstract: The oxygen evolution reaction (OER) is involved in various renewable energy systems,such as water-splitting cells and metal-air batteries.N i-Fel ayered double hydroxides (LDHs) have been reported as promising OER electrocatalysts in alkaline electrolytes.T he rational design of advanced nanostructures for Ni-FeLDHs is highly desirable to optimize their electrocatalytic performance.H erein, we report af acile self-templated strategy for the synthesis of novel hierarchical hollown anoprisms composed of ultrathi… Show more

“…Because of the partially amorphous feature, the catalytically active high‐valence species are prone to generation and stabilization, and thus further realizing enhanced electro‐oxidation activity by means of an internal 2D charge transfer pathway and native Ni 3+ ions. Lou and co‐workers report a simple self‐template strategy for the synthesis of novel layered hollow nanoprisms composed of ultrathin NiFe‐LDHs nanosheets 34. Tetragonal nanoprisms of Ni precursors were first synthesized as the self‐sacrificing template.…”

“…Lou's group successfully synthesized hierarchical hollow nanoprisms composed of ultrathin Ni–Fe LDH nanosheets by self‐sacrificing template method. Nickel‐precursors tetragonal nanoprisms were employed as templates and dissolved by the hydrolysis of iron(II) sulfate for the simultaneous growth of ultrathin Ni–Fe LDH nanosheets on the surface (Figure c) . The wise design of advanced FeNi LDH nanostructures with large surface areas contributed to a low overpotential of 280 mV at 10 mA cm −2 (Figure d).…”
