“…So far, the strategy of the magnetic field effects on enhancing the performance of HER has received wide attention and has been successfully implemented. [255,256] Chen et al [257] investigated the influence and possible mechanism of an external magnetic field intensity and direction on HER with NiMnIn/Ni foams electrocatalyst, and the experimental device is shown in Figure 14b. They found that magnetic field can significantly improve the catalytic activity of NiMnIn/ Ni foams by spin selectivity effect, due to the tiny magnetic poles inside the ferromagnetic NiMnIn film in the same direction as the applied external magnetic field, resulting in that electrons were more easily transferred from Ni foams substrate to the active site, which accelerated the formation of intermediates and a decrease of the slope of Tafel (Figure 14c,d).…”

Metal–air batteries have become one of the new potential sources of electrochemical energy due to the excellent electrochemical characteristics, environmental friendliness and cheap cost. Whereas, the commercialization of the metal–air batteries is still subject to the sluggish kinetics on air electrode and hydrogen evolution corrosion as well as dendrite growth of metal anode. Recently, the applied magnetic field, as a technology for transferring energy across physical space, receives more attention, can improve the performance of metal–air batteries by promoting mass transfer, accelerating charge transfer and enhancing electrocatalytic ability based on magnetohydrodynamic effect, Kelvin force effect, Hall effect, Spin selectivity effect, Maxwell stress effect and Magnetothermal effect. This review provides the recent progress in the research on the relative mechanism and characteristic of the magnetic field in the metal–air batteries.

universal anode reaction for water electrolysis, carbon dioxide reduction, and metalair batteries, which usually requires the use of noble metal catalyst due to the sluggish kinetics. [1] However, due to the high cost and scarcity, large-scale application of noble metals is greatly restricted. Therefore, the development of non-noble metal catalysts with high efficiency and low cost is of great importance. In particular, transition metal-based layer double hydroxides (LDHs) have attracted extensive attention because of their facile synthesis and adjustable composition. [2] The OER performance of LDHs is limited by active sites and poor intrinsic activity. [3] Moreover, due to their semiconductor characteristics, a Schottky barrier may be formed when contacting the conductive substrate, which greatly hinders the charge transfer. [4] A variety of strategies, including size modulation, composite with conductive materials, heteroatomic doping, defect engineering, and interface engineering, have been investigated to further regulate the OER performance of LDHs. [5] It is noteworthy that adjusting the electronic structure of the catalysts can optimize the adsorption energy of the intermediates and improve the reaction kinetics. [5c] In this regard, the construction of p-n heterojunction is a promising strategy to regulate the local electronic structure of catalytically active sites, as the difference of Fermi level (E f ) between n-type semiconductor and p-type semiconductor results in the spontaneous flow of electrons at the interface to achieve thermal equilibrium. As a consequence, the activity, selectivity, and stability can be substantially improved by binary catalysts when compared with single-component catalysts. For example, the p-n junction in FeNi-LDH/CoP with positively charged FeNi-LDH in the space-charge region could greatly improve the OER performance, [6] and the formed CuO@CoOOH p-n heterojunction could remarkably modify the electronic properties and serve as an excellent OER catalyst. [7] In addition to ameliorating the catalyst materials, the emergence of intensification strategies by external fields such as gravity field, light field, ultrasonic, and electric field, has become a new trend in the field of electrochemistry, which can effectively improve the mass transfer on the electrode surface and change the reaction kinetics. [8] Interestingly, the latest research confirms that coupling the magnetic field with electrochemistry Here, a strategy to regulate the electron density distribution by integrating NiFe layered double hydroxides (NiFe-LDH) nanosheets with Co 3 O 4 nanowires to construct the NiFe-LDH/Co 3 O 4 p-n heterojunction supported on nickel foam (NiFe-LDH/Co 3 O 4 /NF) for electrocatalytic oxygen evolution reaction (OER) is proposed. The p-n heterojunction can induce the charge redistribution in the heterogeneous interface to reach Fermi level alignment, thus modifying the adsorption free energy of *OOH and improving the intrinsic activity of the catalyst. As a result, NiFe-LDH/Co 3 ...
