“…Importantly, the overpotential to reach the current density of 10 mA cm −2 can be as low as 310 mV for optimized catalyst composition and loading. Apart from the inherent catalytic activity of composite materials, there is also a question of long-term stability as was shown in a paper by Wang et al [103] In their work, the authors combined nanocrystalline nickel oxide with amorphous manganese oxide suspended on graphene nanosheets. Despite the promising initial catalytic activity, the catalytic activity of this material has deteriorated within few hours of continuous use.…”

Oxygen evolution reaction (OER) is expected to be of great importance for the future energy conversion and storage in form of hydrogen by water electrolysis. Besides the traditional noble‐metal or transition metal oxide‐based catalysts, carbonaceous electrocatalysts are of great interest due to their huge structural and compositional variety and unrestricted abundance. This review provides a summary of recent advances in the field of carbon‐based OER catalysts ranging from “pure” or unintentionally doped carbon allotropes over heteroatom‐doped carbonaceous materials and carbon/transition metal compounds to metal oxide composites where the role of carbon is mainly assigned to be a conductive support. Furthermore, the review discusses the recent developments in the field of ordered carbon framework structures (metal organic framework and covalent organic framework structures) that potentially allow a rational design of heteroatom‐doped 3D porous structures with defined composition and spatial arrangement of doping atoms to deepen the understanding on the OER mechanism on carbonaceous structures in the future. Besides introducing the structural and compositional origin of electrochemical activity, the review discusses the mechanism of the catalytic activity of carbonaceous materials, their stability under OER conditions, and potential synergistic effects in combination with metal (or metal oxide) co‐catalysts.

“…For example, the cost to produce 1kg of hydrogen using grid electricity is currently £11.40, [30] whereas, the cost to produce 1 gallon of diesel is £4. 47. In automotive terms, 1kg of hydrogen is roughly equivalent in mileage to 1 gallon of diesel.…”

“…However, their low reserves and high cost limit the practical application in hydrogen production technology. Thus, in recent years, lots of research work has been devoted to the OER catalytic activity based on non‐noble metal elements (such as NiO x @MnO x , [4] FeCoW oxides, [5] MoS 2 /Ni 3 S 2 , [6] NiFeN x , [7] CuCo 2 N x , [8] CoMP x NRs [9] ). These strategies include controlling the morphology of the catalyst, mixing the main active sites with other auxiliary active sites, using large surface area catalyst supports, etc.…”

To store renewable energy via water splitting, it is crucial to design low‐cost and high‐performance catalysts for oxygen evolution reaction (OER). In this work, a ternary nanowire supported on nickel foam (NiFeAl‐NW/NF) with high specific surface area and catalytic activity was prepared by hydrothermal method and in‐situ selective surface removal. High OER current densities of 100, 500 and 1000 mA ⋅ cm−2 were achieved under anode potentials of 1.52, 1.56 and 1.60 V vs. RHE, respectively. The NiFeAl‐NW/NF was stable under 1 A cm−2 OER current density in the 40 hour durability test. In situ surface selective removal of aluminum from nanowires provides abundant structural defects, which effectively enlarge the electrochemically surface area of the integral catalyst suitable for large‐current oxygen evolution reaction (OER).
