Rational construction of self-supported triangle-like MOF-derived hollow (Ni,Co)Se 2 arrays for electrocatalysis and supercapacitors

In this work, we have adopted a facile three-step method for constructing an intriguing bifunctional electrode of self-supported hollow (Ni,Co)Se2 arrays with a metal-organic framework (MOF) precursor. The triangle-like cobalt-based MOF arrays are first grown on a carbon cloth at room temperature…
