Synergistic Fe-Se Atom Pairs as Bifunctional Oxygen Electrocatalysts Boost Low-Temperature Rechargeable Zn-Air Battery

Yao Wang et al.

Summary: In this study, bifunctional electrocatalysts, Fe-Se/NC, were successfully constructed by synthesizing atomically dispersed Fe-Se atom pairs supported on N-doped carbon. The obtained Fe-Se/NC exhibited remarkable bifunctional oxygen catalytic performance with a low potential difference of 0.698 V, surpassing that of previously reported Fe-based single-atom catalysts. Theoretical calculations revealed that the p-d orbital hybridization around the Fe-Se atom pairs resulted in significantly asymmetrical polarized charge distributions. Moreover, Fe-Se/NC-based solid-state rechargeable Zn-air batteries demonstrated superior cycling and stability compared to the traditional Pt/C+Ir/C catalysts, even at extremely low temperatures.

Longtao Ren et al.

Summary: Constructing high performance electrocatalysts, such as the single atomic catalyst of Fe-N-4 moiety doping periphery with S (Fe-NSC), can effectively enhance lithium polysulfides (LiPSs) adsorption and facilitate sulfur conversion, improving the energy density and cycle life of rechargeable lithium-sulfur (Li-S) batteries. By modifying the graphene oxide supported Fe-NSC catalyst (Fe-NSC@GO) to the commercial separator, Li-S cells exhibit high discharge capacity and excellent cyclability, with 1156 mAh g(-1) at 1 C rate and a low capacity decay of only 0.022% per cycle over 1000 cycles. This work provides new insights into structural tuning of electrocatalysts to improve the electrochemical performance of Li-S batteries.

A General Strategy to Remove Metal Aggregates toward Metal-Nitrogen-Carbon Catalysts with Exclusive Atomic Dispersion

Jianbin Liu et al.

Summary: Metal- and nitrogen-doped nanocarbons (M-N-Cs) are promising alternatives to precious metals for catalyzing electrochemical energy conversion processes. However, M-N-Cs synthesized by high-temperature pyrolysis frequently suffer from compositional heterogeneity with the simultaneous presence of atomically dispersed M-N-x sites and crystalline metal nanoparticles (NPs), which hinders the identification of active sites and rational optimization in performance. A universal and efficient strategy is reported to obtain both precious- and nonprecious-metal-based M-N-Cs with exclusive atomic dispersion by using ammonium iodide as the etchant to remove excessive metal aggregates at high temperature.

Summary: In this study, the possible ways of tuning the morphology of single-crystal NCM materials were investigated through ab initio calculations combined with Wulff shape construction and crystal orbital Hamilton population analysis. Surface structural units with different Miller indices were identified, and a linear relationship between surface energy and the density of cleaved bonds was established. By constructing Wulff shapes, it was found that LiCoO2 had the largest grain size among the studied NCM materials. It was concluded that the surface morphology of NCM can be effectively tuned by modulating the transition metal-O bond strength.
