Electrocatalytic water oxidation on CuO-CuO modulated cobalt-manganese layered double hydroxide.

Layered double hydroxides (LDH) are potential electrocatalysts to address the sluggish oxygen evolution reaction (OER) of water splitting. In this work, copper oxide (CuO/CuO) nanoparticles are integrated with cobalt-manganese layered double hydroxide (CoMn-LDH) to enhance their performance towards OER. The catalyst is synthesized by growing CoMn-LDH nanosheets in the presence of CuO/CuO nanoparticles that were obtained by the calcination of the copper containing metal-organic framework (HKUST-1).

ZIF-12/Fe-Cu LDH Composite as a High Performance Electrocatalyst for Water Oxidation.

Layered double hydroxides (LDH) are being used as electrocatalysts for oxygen evolution reactions (OERs). However, low current densities limit their practical applications. Herein, we report a facile and economic synthesis of an iron-copper based LDH integrated with a cobalt-based metal-organic framework (ZIF-12) to form LDH-ZIF-12 composite (1) through a co-precipitation method.
