“…[ 1 ] Hydrogen is an ideal substitute for fossil fuel energy, and hydrogen production from water splitting is a viable method. [ 2–7 ] However, the anode half‐reaction (oxygen evolution reaction, OER) has a high energy barrier and slow kinetic process, resulting in a great waste of electric energy. [ 8 ] The electrochemical performance enhancement of OER anode is still a serious challenge for the industry application of water splitting.…”

By increasing the content of Ni3+, the catalytic activity of nickel‐based catalysts for the oxygen evolution reaction (OER), which is still problematic with current synthesis routes, can be increased. Herein, a Ni3+‐rich of Ni3S4/FeS on FeNi Foam (Ni3S4/FeS@FNF) via anodic electrodeposition to direct obtain high valence metal ions for OER catalyst is presented. XPS showed that the introduction of Fe not only further increased the Ni3+ concentration in Ni3S4/FeS to 95.02%, but also inhibited the dissolution of NiOOH by up to seven times. Furthermore, the OER kinetics is enhanced by the combination of the inner Ni3S4/FeS heterostructures and the electrochemically induced surface layers of oxides/hydroxides. Ni3S4/FeS@FNF shows the most excellent OER activity with a low Tafel slope of 11.2 mV dec−1 and overpotentials of 196 and 445 mV at current densities of 10 and 1400 mA cm−2, respectively. Furthermore, the Ni3S4/FeS@FNF catalyst can be operated stably at 1500 mA cm−2 for 200 h without significant performance degradation. In conclusion, this work has significantly increased the high activity Ni3+ content in nickel‐based OER electrocatalysts through an anodic electrodeposition strategy. The preparation process is time‐saving and mature, which is expected to be applied in large‐scale industrialization.

Seawater is the most abundant source of molecular hydrogen. Utilizing the hydrogen reserves present in the seawater may inaugurate innovative strategies aimed at advancing sustainable energy and environmental preservation endeavors in the future. Recently, there has been a surge in study in the field addressing the production of hydrogen through the electrochemical seawater splitting. However, the performance and durability of the electrode have limitations due to the fact that there are a few challenges that need to be addressed in order to make the technology suitable for the industrial purpose. The active site blockage caused by chloride ions that are prevalent in seawater and chloride corrosion is the most significant issue; it has a negative impact on both the activity and the durability of the anode component. Addressing this particular issue is of upmost importance in the seawater splitting area. This review concentrates on the newly developed materials and techniques for inhibiting chloride ions by blocking the active sites, simultaneously preventing the chloride corrosion. It is anticipated that the concept will be advantageous for a large audience and will inspire researchers to study on this particular area of concern.
