Fast Electrodeposited Nickel–Iron Hydroxide Nanosheets on Sintered Stainless Steel Felt as Bifunctional Electrocatalyts for Overall Water Splitting

Hydrogen fuel provided by water splitting reaction for storing intermittent renewable energy is an important topic, and electrocatalysis has been a research hot spot. Herein, we report the synthesis of an efficient bifunctional electrocatalytic electrode of nanoporous nickel–iron hydroxides coupled with a small amount of metal Ni/Fe based on stainless steel fiber felt (SSF) by a simple electrodeposition method. The prepared catalysis electrode...
