Water Splitting: Oriented Transformation of Co‐LDH into 2D/3D ZIF‐67 to Achieve Co–N–C Hybrids for Efficient Overall Water Splitting (Adv. Energy Mater. 19/2019)

In article number 1803918, Renbing Wu and co-workers report an easily-manipulated pseudomorphic replication approach to synthesize 2D ZIF-67 nanosheets grafted with 3D ZIF-67 polyhedra architecture on the surface of carbon cloth (CC). After a pyrolysis process, 2D/3D ZIF-67@CC can be further converted into a electrocatalyst that consists of cobalt nanoparticles embedded within both 2D carbon nanosheets and 3D hollow carbon polyhedra, exhibiting an excellent overall water-splitting performance.
