Pr6O11 clusters anchored CoFe-LDH on vertical graphene nanosheets as oxygen evolution electrocatalyst for long-term high-current-density seawater electrolysis

Our synthesized seawater OER electrocatalyst GP/VGSs-CoFe LDH-Pr 6 O 11 shows excellent catalytic activity and stability (with the aid of K 2 SO 4 ) in overall alkaline seawater electrolysis, combining a previously reported HER electrocatalyst NiMoN.
