In situ synthesis of hierarchical NiCo-MOF@Ni1−xCox(OH)2 heterostructures for enhanced pseudocapacitor and oxygen evolution reaction performances

A novel 3D hierarchical NiCo-MOF@Ni_1−xCo_x(OH)₂ heterostructure with ultrathin nanosheets was prepared, which could take full advantage of the two components and their unique heterostructure, resulting in superior pseudocapacitor and OER performances.
