A solvent-induced crystal-facet effect of nickel–cobalt layered double hydroxides for highly efficient overall water splitting

Abstract

Two-dimensional layered materials have been universally acknowledged to be promising candidates for alternative precious metal in the field of catalysis. The crystal-facet effect is currently rare in the field of...

CoFe layered double hydroxides with adjustable composition and structure for enhanced oxygen evolution reaction

“…4a). In detail, Co LDH showed strong peaks at 464 cm À1 and 532 cm À1 , which can be assigned to the E g vibration mode of Co-O-H. 50,51 For Fe LDH, the peak at 684 cm À1 corresponded to the E g vibration mode of Fe-O-H. The peak at 1079 cm À1 in Co LDH and that at 1294 cm À1 in Fe LDH corresponded to CO 3 2À .…”

Construction of a phosphorus-based integrated electrode for efficient and durable seawater splitting at a large current density

“…20,21 Chen et al prepared Ru-doped catalytic electrodes with high intrinsic activity via a hydrothermal method, achieving an overall water-splitting performance of 1.560 V that surpassed integrated RuO 2 and platinum/carbon coupling electrodes. 22,23 However, the stability of a series of highly loaded noble metals, and prepared electrodes under high current density catalysis remains a major challenge. 24 The theoretical and experimental research results indicate that Ru possesses strong adsorption capabilities for hydrogen and oxygen intermediates.…”
