Formation Of Porous Nicov-Lth Nanosheet Arrays By In Situ Etching Of Nickel Foam For The Hydrogen Evolution Reaction At Large Current Density

We report the in situ generation of NiCoV-LTH on nickel foam for the HER. Interestingly, the introduction of Co into NiV-LDH can induce the formation of porous nanosheets to expose a large number of active sites and change the electron density around Ni and V to promote the absorption of hydrogen species and thus accelerate the HER kinetics.
