A Co-MOF nanosheet array on Ni foam (Co-MOF/NF) acts as a superior electrocatalyst for the oxygen evolution reaction, needing an overpotential of only 311 mV to drive a geometrical catalytic current density of 50 mA cm−2 in 1.0 M KOH.
A Ni2P nanosheet array integrated on Ni foam performs as a catalyst for on-demand hydrogen production from ammonia borane with an initial turnover frequency of 42.3 mol(H2) mol(Ni2P)−1 min−1 and an activation energy of 44.0 kJ mol−1.
