Strongly Coupled CoCr2O4/Carbon Nanosheets as High Performance Electrocatalysts for Oxygen Evolution Reaction

A strongly coupled CoCr2O4/carbon nanosheet composite is concurrently grown via a facile one‐step molten‐salt calcination approach. The strong coupling between carbon and CoCr2O4 has improved the electrical conductivity and preserved the active sites in catalysts. These results may pave the way to i...

Summary:A strongly coupled CoCr2O4/carbon nanosheet composite is concurrently grown via a facile one‐step molten‐salt calcination approach. The strong coupling between carbon and CoCr2O4 has improved the electrical conductivity and preserved the active sites in catalysts. These results may pave the way to improve the performance of spinel oxides as electrocatalysts for oxygen evolution reactions.
