“…Although the oxides of Ru and Ir have always been considered the benchmark for OER catalysts in acid and base owing to their high catalytic activity, they inevitably suffer from low abundance and high cost of precious metals, which pose tremendous limitations to their widespread use . An increased effort has been given to develop low‐cost, high‐efficient and durable electrode materials to substitute noble metal OER catalysts, such as first‐row transition metal catalysts, metal‐free catalysts, and perovskites . These catalysts can be fixed by polymer binders such as Nafion onto glassy carbon or Au electrodes, although some of them can also be directly grown or deposited on current collectors such as foams, meshes, plates, carbon clothes or papers, and indium‐doped tin oxide (ITO) or fluorine‐doped tin oxide (FTO) glasses.…”

Developing low cost and efficient anode and cathode materials toward electrocatalysis are regarded as one of the most desirable yet challenging research directions, which are intimately related to the pressing energy, environmental and human health issues. Currently, 3 D foam (such as Ni foam, Cu foam, and graphene foam) based heterogeneous catalysts have been intensively explored for actively catalyzing the electrode reactions. Their inherent characteristics of stereo‐network structure, high specific area and large pore volume not only provide better mass transport of reactants to electrode surfaces, but also pave 3 D electron transport pathways. Herein, recent significant progress and rational design of foam‐based electrocatalysts are reviewed. In addition, some insights into current challenges and future directions of foams for efficient electrocatalysis are proposed and discussed.

“…However, the use of conducting additive and binder unavoidably increases the undesirable interparticle resistance which decreases the efficiency of electron transport among active materials. Comparing to the powder electrode, it was shown that direct growth of electrode materials arrays on conductive substrates [29][30][31][32][33] could conquer the shortcoming compared to the power electrode. For example, CuCo 2 O 4 nanograss on a Cu foam substrate has hold specific capacitances of 796 F g -1 at 2 A g -1 [17].…”

“…We further compared the operating potentials of different catalysts to deliver a 10-mA cm −2 current density. It even showed superior performance to those of previously reported OER catalysts with the same configuration, such as NiCo 2 S 4 @N/S-graphene [30], Co x S y @N/S-C [46], NiO nanosheets [47], and FeNC sheets/NiO [48], which demonstrates that NiO-NiS/N-C is among the most efficient.…”

Efficient electrocatalysts for the oxygen evolution reaction (OER) are critical for various energy conversion devices such as metal-air batteries, rechargeable fuel cell, and water splitting for hydrogen production. In this work, a novel non-precious-metal OER catalyst was prepared from the pyrolysis of a Ni-Schiff base complex with thiourea. The derived catalyst is composed of nickel oxide coupled with nickel sulfide loaded on nitrogen-doped carbon matrix (NiO-NiS/N-C), which manifested excellent OER electrocatalytic activity, and an onset potential of 1.54 V vs reversible hydrogen electrode was achieved in alkaline electrolyte. The high performance of as-obtained electrocatalyst was illustrated by fully dispersed active components of NiO coupled with NiS nanoparticles, as well as the strong interaction between NiS, NiO particles, and N-doped carbon substrate. Our findings supply an easier path to fabricate the active catalyst through one-step metal organic framework transformation way and are promising for use in energy conversion systems and also yield new impetus for exploring other non-noble metal catalysts.
