Abstract :
Aqueous zinc metal batteries (ZMBs) are regarded as strong contenders in secondary battery systems due to their high safety and abundant resources. However, the cycling performance of the Zn anode and the overall performance of the cells have often been hindered by the formation of Zn dendrites and the occurrence of parasitic side reactions. In this paper, a surface electron reconfiguration strategy is proposed to optimize the adsorption energy and migration energy of Zn2+ for a better Zn2+ deposition/stripping process by adjusting the electronic structure of ceric dioxide (CeO2) artificial interface layer with copper atoms (Cu) doped. Both experimental results and theoretical calculations demonstrate that the Cu2Ce7Ox interface facilitates rapid transport of Zn2+ due to the optimized electronic structure and appropriate electron density, leading to a highly reversible and stable Zn anode. Consequently, the Cu2Ce7Ox@Zn symmetric cell exhibits an overpotential of only 24 mV after stably cycling for over 1600 h at a current density of 1 mA/cm2 and a capacity of 1 mAh/cm2. Additionally, the cycle life of Cu/Zn asymmetric cells exceeds 2500 h, with an average Coulombic efficiency of 99.9%. This paper provides a novel approach to the artificial interface layer strategy, offering new insights for improving the performance of ZMBs.

Abstract :
Cobalt and iron selenides-based materials with high theoretical capacities, low toxicity and abundant sources have been identified as the promising anode materials for sodium-ion batteries (SIBs). However, they still face the challenges of high volume expansion and slow electrode kinetics, resulting in poor rate performance and fast capacity fading. In this paper, three-dimensional honeycomb-like Co-Fe based selenide composites with different molar ratios are successfully synthesized by one-pot solvothermal, annealing and selenization processes (expressed as Co-FeSe2@C/CNs-fbs, Co-FeSe2@C/CNs-irs and Co-FeSe2@C/CNs-sbs). Benefitted from the design of three-dimensional porous compositing structure, the optimized Co-FeSe2@C/CNs-fbs electrode material possesses more active sites and structural stability, resulting in stable cycling performance and fast electron/ion transport. As a result, Co-FeSe2@C/CNs-fbs anode shows excellent rate capability (353.1 mAh g-1 at 120 A g-1) and long cycling performance (95.7% of capacity retention after 3700 cycles at 60 A g-1), surpassing most previously reported anode materials for SIBs. Meanwhile, a full-cell made up with Na3V2(PO4)3/C cathode and Co-FeSe2@C/CNs-fbs anode shows a high energy density (180.1 Wh kg-1 at a power density 630.5 W kg-1) and capacity retention rate. This study provides a feasible strategy to fabricate selenide-based composites as the anode materials for high-performance SIBs via doping and structure engineering.

Abstract :
Passivation of magnesium (Mg) anode in the chloride-free magnesium bis(trifluoromethanesulfonyl)imide (Mg(TFSI)(2)) electrolyte is a key challenge for Mg metal batteries. Tailoring solvation structure and solid electrolyte interphase (SEI) has been considered an effective strategy. Herein, a series of imidazole co-solvents with different branched-chain structures (methyl, ethyl, and propyl) are introduced into the Mg(TFSI)(2)-ether electrolyte to address the passivation issue. The ion-solvent interaction, interfacial adsorption effect, and SEI formation are comprehensively studied by theoretical calculations and experimental characterizations. Through molecular structure analysis, the long-chain 1-propylimidazole (PrIm) exhibits a strong coordination ability to Mg2+ and a favorable parallel adsorption configuration on the Mg surface. As a result, PrIm co-solvent can not only restructure the solvation sheath of Mg2+, but also act as a dynamic protective shield to repel a part of TFSI- and 1,2-dimethoxyethane (DME) away from the Mg surface. Benefiting from the synergistic regulation effect of interfacial chemistry and ion-solvent interactions, the chloride-free Mg(TFSI)(2)-DME + PrIm electrolyte ensures minimal interface passivation and achieves highly reversible Mg plating/stripping. This work provides a guiding strategy for solvation structure regulation and interface engineering for rechargeable Mg metal batteries.

Abstract :
Modulating the electron delocalization of catalysts can improve the activation and conversion capabilities of lithium polysulfides (LiPSs) in lithium-sulfur batteries, while the precise mechanism underlying this enhancement remains unclear. Herein, a p-block In single-atom catalysts (In-N4) is constructed with moderate electron delocalization via axial coordination engineering of gallium nitride (GaN), which exhibits the best adsorption and electrocatalytic activity toward LiPSs. In situ characterization analysis combined with advanced theoretical calculations demonstrate that the axial In-N-Ga coordination induces the electron transfer from In sites toward the N sites of GaN and the unconventional sp3d2 hybridization interactions of In sites. This further helps to optimize adsorption configuration through the orbital hybridization between sp3d2 hybrid orbital of In sites and p orbital of S atoms in LiPSs, namely the sp3d2 - p orbital hybridization, which can weaken S-S covalent bonds of LiPSs and significantly accelerate the sulfur reduction reaction. Accordingly, the capacity decay of lithium-sulfur battery with In-SA/GaN catalyst is only 0.040% per cycle over 800 cycles at 5 C. The stacked pouch cell delivers a reversible capacity of 600 mAh after 100 cycles. This work elaborates on the activity origin of p-block metal catalysts and provides a new perspective on designing advanced catalysts for other catalytic systems.

Abstract :
Layered double hydroxide (LDH) materials have been of interest as the noble metal substitutes for oxygen evolution reaction (OER) in alkaline media though their intrinsically inferior electrocatalytic activity. Proper cation vacancy engineering of LDH is an effective approach for improving intrinsic activity during catalytic OER. In this work, the in-situ formation of cation vacancies in LDH nanosheets (NiFeCoZnvac-LDH) is successfully realized by partially Zn etching from medium-entropy NiFeCoZn-LDH precursor. In-situ Raman analysis and DFT calculations uncover that the introduction of metal cation vacancies can significantly lower the generation potential of the surface reconstruction for the formation of abundant high-valence active centers and optimize the adsorption/desorption energy of oxygen-containing intermediates, thereby boosting catalytic OER activity. As a proof of concept, the obtained NiFeCoZnvac-LDH catalyst just requires a low overpotential of 222 mV to reach a current density of 10 mA cm-2 with a small Tafel slope of 37.17 mV dec-1. Furthermore, the NiFeCoZnvac-LDH electrode takes an ultralow potential of 1.48 V at 10 mA cm- 2 in practical anion exchange membrane electrolyzer and operate stably at 100 mA cm- 2 for long period without obvious activity attenuation. The present study enables the development of LDH catalysts for efficient water oxidation using a simple and robust approach.

Abstract :
Developing asymmetric heteronuclear dual-atom catalysts (DACs) through coordination microenvironment regulation and investigating their structure-activity relationship for the catalytic oxygen reduction reaction (ORR) are crucial for energy conversion and storage devices such as zinc-air batteries (ZABs). In this work, a novel catalyst with its Fe and Zn diatomic sites atomically dispersed on nitrogen-doped hierarchical porous carbon (FeZn-NC-800) was designed and synthesized under a cyanamide-assisted sintering atmosphere to stabilize Zn single atoms in the structure. Benefiting from specific synergy between the Fe and Zn atoms and the hierarchical porous carbon substrate, the obtained FeZn-NC-800 catalyst exhibits remarkable ORR performance with a positive half-wave potential of 0.89 V and good durability, outstripping the performance of most state-of-the-art catalysts and commercial precious metal catalysts. Moreover, the ZABs assembled with the FeZn-NC-800 cathodes exhibit an excellent peak power density of 218.6 mW cm-2 and achieve stable cycling for over 200 hours at a current density of 10 mA cm-2. This study provides a fresh new insight into the development of stable and highly active DAC materials, advancing the design of next-generation energy technologies.

Abstract :
Introducing advanced conductive nanoparticles to combine with metal-organic frameworks (MOFs) as electrode is emergingly regarded as a practical and efficient approach to improve the capacitive performance of super- capacitors. Herein, a new MOF (ZrNi-UiO-66, Nickel-zirconium 1,4-dicarboxybenzene) is designed to combine with carbon quantum dots (CQDs) to form a composite electrode with high specific capacitance, in which the charge regulation is performed to facilitate the electronic conduction and transfer. Such constructed electrode delivers an enhanced electronic conductivity and an improved specific capacitance of 2468.75 F g- 1 @ 1 A g- 1 , which is four times of the contrast sample. Meanwhile, the assembled hybrid supercapacitor exhibits an increased energy density and power density, as well as a sustainable stability after 10,000 cycles with a retention rate of 91.6 %. Basing on the study of advanced characterizations and density functional theory (DFT) simulation, the mechanism of significantly improved specific capacitance can be elaborated as the promote electronic conduction caused from narrowed band gap from 3.9 eV or 0.41 eV-0.23 eV, and the increased charge accumulation at the Ni sites in designed MOFs. This work provides new insights for the design and construction of potential energy storage materials based on MOFs and/or advanced carbon-based materials.

Abstract :
Nitrate electroreduction is promising for achieving effluent waste-water treatment and ammonia production with respect to the global nitrogen balance. However, due to the impeded hydrogenation process, high overpotentials need to be surmounted during nitrate electroreduction, causing intensive energy consumption. Herein, a hydroxide regulation strategy is developed to optimize the interfacial H2O behavior for accelerating the hydrogenation conversion of nitrate to ammonia at ultralow overpotentials. The well-designed Ru & horbar;Ni(OH)(2) electrocatalyst shows a remarkable energy efficiency of 44.6% at +0.1 V versus RHE and a nearly 100% Faradaic efficiency for NH3 synthesis at 0 V versus RHE. In situ characterizations and theoretical calculations indicate that Ni(OH)(2) can regulate the interfacial H2O structure with a promoted H2O dissociation process and contribute to the spontaneous hydrogen spillover process for boosting NO3 (-) electroreduction to NH3 at Ru sites. Furthermore, the assembled rechargeable Zn-NO3 (-)/ethanol battery system exhibits an outstanding long-term cycling stability during the charge-discharge tests with the production of high-value-added ammonium acetate, showing great potential for simultaneously achieving nitrate removal, energy conversion, and chemical synthesis. This work can not only provide a guidance for interfacial H2O regulation in extensive hydrogenation reactions but also inspire the design of a novel hybrid flow battery with multiple functions.

Abstract :
Currently, ammonia is an important chemical in modern society, widely used in agriculture and energy-conversion fields. However, there are existing energy-consumption and environmental problems in the traditional process of ammonia synthesis. At present, electrochemical nitrate reduction reaction (NO3-RR) uses renewable electricity as power to achieve simultaneous nitrate removal and ammonia generation, providing an efficient, green and clean platform for sustainable ammonia synthesis. As an ideal model material for electrochemistry research, two-dimensional (2D) materials with tunable surface properties and electronic structure have aroused immense interest in electrocatalysis applications. The atomic-layer structure of 2D materials can significantly affect their physical/chemical properties, while size and surface characteristics are important aspects to be considered for designing and synthesizing efficient catalysts to achieve the high performance of the electrocatalytic NO3-RR application. In this review, we discuss the fundamentals of electrocatalytic nitrate reduction to ammonia including reaction mechanisms and basic research methods. Moreover, synthetic methods and design strategies of 2D-material electrocatalysts are introduced and specific applications of 2D material in electrocatalytic NO3-RR are demonstrated. Furthermore, future perspectives are proposed to inspire novel attempts for new 2D materials applications across broad fields.
