PG - 400-408 LID - 10.1002/chem.201703796 [doi] AB - Highly active, durable, and cost-effective electrocatalysts for water oxidation are at the center of renewable energy technologies. However, the development of water oxidation catalysts with high activity at low cost remains a great challenge. Herein, an in situ antisolvent approach is reported for synthesizing ultrathin Co-Ni layered double hydroxide (CoNi-LDH) nanosheets wrapped on hollow Co(3) O(4) nanoparticle-embedded nitrogen-doped carbon (HCo(3) O(4) -NC) as a high-performance catalyst for the oxygen evolution reaction (OER). Although HCo(3) O(4) -NC or NiCo-LDH alone has little OER activity, their hybrid exhibits low overpotential and Tafel slope as well as high stability, due to the synergistic effect of Co(3) O(4) and LDH. Furthermore, the hydrangea-like HCo(3) O(4) -NC@NiCo-LDH core@shell composite exhibits higher catalytic activity and stability than commercial IrO(2) , which makes it a high-performance nonprecious-metal-based catalyst for OER.
