A novel endophytic actinomycete, designated strain NEAU-J3(T), was isolated from soybean root (Glycine max (L.) Merr) and characterized using a polyphasic approach. Phylogenetic analysis based on 16S rRNA gene sequences suggested that strain NEAU-J3(T) fell within the family Micromonosporaceae. The strain was observed to form an extensively branched substrate mycelium, which carried non-motile oval spores with a smooth surface. The cell walls of strain NEAU-J3(T) were determined to contain meso-diaminopimelic acid and galactose, ribose and glucose were detected as whole-cell sugars. The major menaquinones were determined to be MK-9(H-4) and MK-9(H-6). The phospholipids detected were phosphatidylcholine and phosphatidylethanolamine. The major cellular fatty acids were determined to be C-16:0, C-18:1 omega 9c, C-18:0, C-17:0, C-17:1 omega 7c, anteiso-C-17:0, C-16:1 omega 7c and C-15:0. The DNA G + C content was 62.5 mol%. On the basis of the morphological and chemotaxonomic characteristics, phylogenetic analysis and characteristic patterns of 16S rRNA gene signature nucleotides, strain NEAU-J3(T) is considered to represent a novel species of a new genus within the family Micromonosporaceae, for which the name Wangella harbinensis gen. nov., sp. nov. is proposed. The type strain of Wangella harbinensis is strain NEAU-J3(T) (=CGMCC 4.7039(T) = DSM 45747(T)).

Stable Sn@Cu foam enables long cycling life of zinc metal anode for aqueous zinc batteries

Bo Tang, Hefei Fan, Qianfeng Liu, Qiang Zhang, Min Liu, Erdong Wang

Summary: This study reports a stable Sn@Cu foam prepared by plating tin on copper foam as a substrate for zinc anodes. The Sn@Cu foam not only inherits the advantages of the copper foam but also suppresses hydrogen evolution reaction and lowers the initial heterogeneous nucleation barrier of deposited zinc. In situ observation confirms the suppression of zinc dendrite growth on the Sn layer. As a result, a compact zinc layer on Sn@Cu foam is obtained, which exhibits a longer cycling life and better cycling stability.

Tailoring interfacial Zn2+ coordination via a robust cation conductive film enables high performance zinc metal battery

Hefei Fan, Min Wang, Yanbin Yin, Qianfeng Liu, Bo Tang, Gongquan Sun, Erdong Wang, Xianfeng Li

Summary: Aqueous rechargeable zinc metal batteries have gained significant attention for their high capacity, safety, and cost-effectiveness. However, limited lifespan and Coulombic efficiency of Zn metal anodes have hindered their widespread use. In this study, a Zn2+ ion-exchanged sulfonated poly (ether ketone) film is constructed on the Zn metal anode, which effectively inhibits dendrite formation and side reactions, and improves Zn2+ transfer kinetics.

Surface-Oxidized Iron-Cobalt-Nickel Alloy with Continuous Variable Composition for Hydrogen and Oxygen Evolution Reaction

Qianfeng Liu, Zhao Yan, Jianxin Gao, Erdong Wang

Summary: The composition of alloy-based electrocatalysts plays a key role in optimizing their electroactivity for the hydrogen evolution reaction (HER) and oxygen evolution reaction (OER). This study investigates the electrocatalytic properties of FeCoNi-based alloys with varying compositions. The results show that alloys with low iron content exhibit higher HER activity, while alloys with low cobalt content exhibit higher OER activity. The addition of iron and cobalt increases the electrochemical specific area, leading to improved HER activity and stability. Surface hydroxides enhance the HER activity of most compositions, but have little effect on OER activity.

Manganese-doped cobalt spinel oxide as bifunctional oxygen electrocatalyst toward high-stable rechargeable Zn-air battery

Xiaoke Zhang, Qianfeng Liu, Shimin Liu, Erdong Wang

Summary: A series of Mn-doped Co3O4 nanoparticles grown on carbon nanotubes (Mn-Co3O4@CNTs) bifunctional electrocatalysts are designed for rechargeable Zn-air batteries, aiming for high-performance and low-cost catalysts. The Mn-Co3O4 with moderate doping of Mn atoms exhibits enhanced ORR activity due to the synergistic effect between Co and Mn atoms, and more Co3+ active sites are exposed on the surface to enhance the OER rate. The Mn-Co3O4@CNTs catalyst with 40% Mn doping shows higher ORR and OER performance, and when applied in rechargeable ZAB, it demonstrates excellent power density, low charge-discharge voltage gap, and superior cycling stability compared to Pt-and Ru-based ZABs.

A chloride-free electrolyte to suppress the anodic hydrogen evolution corrosion of magnesium anode in aqueous magnesium air batteries

Jianxin Gao, Xiaotong Li, Qianfeng Liu, Hefei Fan, Shanshan Gao, Yujiang Song, Erdong Wang

Summary: Aqueous magnesium air batteries have the advantages of high theoretical energy density, inherent safety, and low cost. However, the practical energy density is limited by the hydrogen evolution corrosion of the magnesium (Mg) anode in conventional sodium chloride (NaCl) electrolyte. In this study, the hydrogen evolution reaction on the Mg anode surface is suppressed by using sodium acetate (NaAc) electrolyte, resulting in uniform anodic dissolution behavior of Mg without localized corrosion. The addition of acetate ions (Ac-) effectively prevents the breakdown of the passive film on the Mg anode, suppressing the anodic hydrogen evolution during discharge. This approach significantly improves the utilization efficiency of the Mg anode and boosts the specific energy of the Mg air battery. The practicality of NaAc electrolyte is confirmed in a commercial Mg air battery, providing a simple and scalable solution for high-performance Mg air batteries.

Exploring the effect of ion concentrations on the electrode activity and stability for direct alkaline seawater electrolysis

Tengteng He, Qianfeng Liu, Hefei Fan, Yang Yang, Hongtao Wang, Shengzhong Zhang, Ruxin Che, Erdong Wang

Summary: Studying the changes in electrode activity and stability caused by increasing ion concentration in alkaline seawater electrolysis is essential for industrial-level seawater electrolysis. This study investigates the concentration of hydroxide ion (OH-), chlorine ion (Cl-), and other ions in alkaline seawater (OIAS) to understand the activity and stability of nickel foam (NF) electrodes in hydrogen evolution reaction (HER) and oxygen evolution reaction (OER). Overall, the activity of HER electrode decreases with increasing OH- concentration, while the OER electrode is enhanced by increasing OH- and Cl- concentration. However, increasing ion concentrations (OH-, Cl-, and OIAS) decrease the stability of HER electrode, while Cl- reduces the stability and OH- and OIAS enhance the stability of OER electrode. Additionally, the chloride evolution reaction (ClER) in 6 M NaOH with seawater can be ignored despite reaching saturation of salt concentration in alkaline seawater.

Xiaoke Zhang, Qianfeng Liu, Zhao Yan, Shimin Liu, Erdong Wang

Summary: In this study, CuO/Co3O4@CNTs catalysts were successfully prepared for bifunctional oxygen electrocatalysts using a facile and scalable coprecipitation strategy. This unique strategy allowed the uniform growth of CuO/Co3O4 nanoparticles on CNTs and the simultaneous pyrolysis process resulted in the generation of ultrafine CuO/Co3O4 heterostructures. Due to an abundance of heterostructures, oxygen vacancies and unsaturated chemical bonds were generated in CuO/Co3O4. As a result, CuO/Co3O4@CNTs exhibited bifunctional activity with a Delta E of 0.78 V and good stability, maintaining 1000 hours of charge and discharge cycles.
