Interface engineering of Co3Fe7-Fe3C heterostructure as an efficient oxygen reduction reaction electrocatalyst for aluminum-air batteries

A review of sodium chloride-based electrolytes and materials for electrochemical energy technology

“…161 Therefore, the development of novel strategies to improve the performance of the Al-air battery with neutral electrolyte represented by the NaCl-based electrolyte has attracted more and more attention in recent years. [162][163][164][165][166] Similarly, two common strategies for optimizing the Al-air battery based on the NaCl-based electrolyte are the alloying of the Al electrode with Mg, Ga, Sn, Mn, Zn, Bi, Pb, and/or In, and so on, [167][168][169][170][171] and the addition of corrosion inhibitors to the NaClbased electrolyte. 137,172 For example, an Al-air battery based on Al-Mg-Ga-Sn-Mn in 2 M NaCl solution offered higher operating voltage and anodic utilization than those with Al, 167 and the Al-Bi-Pb-Ga alloy provided a more negative potential and exhibited enhanced activity in NaCl solution as compared with pure Al and Al-Bi-Pb alloys.…”

Co/MoC Nanoparticles Embedded in Carbon Nanoboxes as Robust Trifunctional Electrocatalysts for a Zn–Air Battery and Water Electrocatalysis

“…Lately, preparing suitable interface structures has become one of the most feasible and effective strategies to boost the electrochemical efficiency, selectivity, and stability during the ORR, OER, and HER electrocatalysis . Previous research studies have indicated that interface engineering could create not only structural discontinuity to accelerate interfacial charge-transfer between adjacent domains but also abundant high-energy defects to improve electrocatalysis . Moreover, the heterointerface with suitable composition and structure complexity may show collective catalytic functions resulting from each heterogeneous component, thus providing the possibility for the fabrication of trifunctional catalysts toward diversified catalytic devices .…”

Double‐Shelled Hollow SiO2@N‐C Nanofiber Boosts the Lithium Storage Performance of [PMo12O40]3−

“…The disordered carbon structure can enhance lithium intercalation by lowering the energy barrier and then further improve lithium storage. [34,36] The cyclic voltammogram (CV) curves of the PMo 12 À SiO 2 @NÀ C were scanned from 0.01 to 3.0 V at a scan rate of 0.1 mV s-1 (Figure 3a). Two reduction peaks at around 0.75 and 1.62 V were observed in the first cycle, but disappeared in the subsequent cycles, which were attributed to the SEI film formation (0.75 V) and the irreversible electrolyteelectrode side reaction (1.62 V) during the first discharging process.…”
