Rational construction of loosely packed nickel nanoparticulates with residual HCOO ligands derived from a Ni-MOF for high-efficiency electrocatalytic overall water splitting

Loosely packed nanoparticulate Ni-250-2@NF architecture with the existence of residual HCOO ligands from Ni-MOF@NF exhibits remarkable electrocatalytic HER, OER and overall water splitting activities.
