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.

Synergistic Effects of Interfacial Chemistry and Ion-Solvent Interactions to Enable Reversible Magnesium Metal Anode in Chloride-Free Mg(TFSI)2 Electrolytes SCIE

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.

Rapid Two Surface Reconstructions of Ni/MnO Heterojunction for Superior Urea Electrolysis SCIE
期刊论文 | 2024 , 9 (9) , 4682-4690 | ACS ENERGY LETTERS
Abstract&Keyword Cite

Abstract :

Urea oxidation reaction (UOR) emerges as a promising alternative anodic half-reaction to oxygen evolution reaction (OER) in an electrochemical CO2 reduction reaction (ECRR) system. Herein, a Ni/MnO heterojunction with extraordinary UOR activity is synthesized on Ni foam. Ex situ/in situ characterization and theoretical calculation reveal that the outstanding UOR performance of Ni/MnO catalyst can be ascribed to two successive surface reconstructions. In the first and second surface reconstructions, Ni(OH)(2)/MnOOH and NiOOH/MnOOH heterojunctions are formed on the catalyst surface, and Mn and Ni sites serve as the active sites, respectively. The heterojunctions formed can enhance UOR activity by reducing the surface reconstruction potential and optimizing the adsorption energy of intermediates through electronic structure modulation and d-band center regulation. When employed as the UOR anode in the CO2 electrolyzer, it requires 375 mV less voltage at 10 mA cm(-2) than the OER, revealing the great potential of applying such Ni/MnO catalyst as the anodic UOR in an ECRR system for carbon neutrality.

Abstract :

CO and H 2 S poisoning of Pt -based catalysts for hydrogen oxidation reaction (HOR) stands as one of the longstanding hindrances to the widespread commercialization of proton exchange membrane fuel cells. In this paper, a Ru/Ti 4 O 7 catalyst is successfully synthesized by the microwave -thermal method. This Ru/Ti 4 O 7 catalyst shows a much higher noble metal mass activity than those of commercial PtRu/C and conventional Ru/C catalysts. The performance of the Ru/Ti 4 O 7 catalyst under the exist of CO or H 2 S shows insignificant current decay, which is far superior to commercial PtRu/C and Pt/C catalysts. In this Ru/Ti 4 O 7 catalyst, the electron transfer between Ru and Ti to form d -p orbital hybridization is considered to be responsible for the favorable catalytic HOR performance and the corresponding CO and H 2 S tolerance. The interaction mechanism formed by electron transfer may open a promising way for the subsequent development of anti -poisoning catalysts for PEM fuel cell hydrogen oxidation reaction.

Ni and Co Active Site Transition and Competition in Fluorine-Doped NiCo(OH)2 LDH Electrocatalysts for Oxygen Evolution Reaction SCIE

Abstract :

The oxygen evolution reaction (OER) performance of NiCo LDH electrocatalysts can be improved through fluorine doping. The roles of Ni and Co active sites in such catalysts remain ambiguous and controversial. In addressing the issue, this study draws upon the molecular orbital theory and proposes the active center competitive mechanism between Ni and Co. The doped F-atoms can directly impact the valence state of metal atoms or exert an indirect influence through the dehydrogenation, thereby modulating the active center. As the F-atoms are progressively aggregate, the e(g) orbitals of Ni and Co transition from e(g)(2) to e(g)(1), and subsequently to e(g)(0). The corresponding valence state elevates from +2 to +3, and then to +4, signifying an initial increase followed by a subsequent decrease in the electrocatalytic performance. Furthermore, a series of F-NiCo LDH catalysts are synthesized to verify the e(g) orbital occupancy analysis, and the catalytic OER overpotentials are 303, 243, 240, and 246 mV at the current density of 10 mA cm(-2), respectively, which coincides well with the theoretical prediction. This investigation not only provides novel mechanistic insights into the transition and competition of Ni and Co in F-NiCo LDH catalysts but also establishes a foundation for the design of high-performance catalysts.

Amorphization-induced abundant coordinatively unsaturated Ni active sites in NiCo(OH)2 for boosting catalytic OER and HER activities at high current densities for water-electrolysis SCIE

Abstract&Keyword Cite

Abstract :

The large overpotential required for oxygen evolution reaction (OER) is one of the major factors limiting the efficiency of electrochemical water-electrolysis for hydrogen production. In this work, to decrease OER energy barrier and obtain low overpotential, amorphous-crystalline NiCo(OH)2 nanoplates are in-situ grown on nickel foam surface to form a catalyst-based electrode (ac-NiCo(OH)2/NF) for water-electrolysis application. As the inner amorphization of NiCo(OH)2 results in increased electron density of the metal sites, leading to the formation of tensile Ni-O bond, the coordinatively unsaturated Ni sites in the down-shift d-band centers toward Fermi level can lower the anti-bonding states. This can lead to optimized adsorption and desorption energies for oxygen-containing intermediates for OER. As expected, the prepared ac-NiCo(OH)2/NF electrode presents a low overpotential of 364 mV to deliver 1000 mA cm-2 toward OER with impressively high robust stability. When this electrocatalyst electrode serves as both the anode and cathode, the assembled anion exchange membrane (AEM) electrolyser only needs a cell voltage of 1.68 V to drive the overall water-electrolysis process at a current density of 10 mA cm-2.

Heterojunction Vacancies-Promoted High Sodium Storage Capacity and Fast Reaction Kinetics of the Anodes for Ultra-High Performance Sodium-Ion Batteries SCIE

Abstract&Keyword Cite

Abstract :

Transition metal sulfides as anode materials for sodium-ion batteries (SIBs) have the advantage of high capacity. However, their cycle-life and rate performance at ultra-high current density is still a thorny issue that limit the applicability of these materials. In this paper, the carbon-embedded heterojunction with sulfur-vacancies regulated by ultrafine bimetallic sulfides (vacancy-CoS2/FeS2@C) with robust interfacial C-S-Co/Fe chemical bonds is successfully synthesized and explored as an anode material for sodium-ion battery. By changing the ratio of two metal cations, the concentration of anion sulfur vacancies can be in-situ adjusted without additional post-treatment. The as-prepared vacancy-CoS2/FeS2@C anode material offers ultrahigh rate performance (285.1 mAh g-1 at 200 A g-1), and excellent long-cycle stability (389.2 mAh g-1 at 40 A g-1 after 10000 cycles), outperforming all reported transition metal sulfides-based anode materials for SIBs. Both in-situ and ex-situ characterizations provide strong evidence for the evolution mechanism of the phases and stable solid-electrolyte interface (SEI) on the vacancy-CoS2/FeS2@C surface. The density functional theory calculations show that constructing heterojunction with reasonable concentration of vacancies can significantly increase the anode electronic conductivity. Notably, the assembled vacancy-CoS2/FeS2@C//Na3V2(PO4)3/C full-cell shows a capacity of 226.2 mAh g-1 after 400 cycles at 2.0 A g-1, confirming this material's practicability. The carbon-embedded heterojunction with sulfur-vacancies regulated by ultrafine bimetallic sulfides (vacancy-CoS2/FeS2@C) is successfully synthesized and explored as an anode material for sodium-ion battery. The mechanism of vacancy-CoS2/FeS2@C for sodium storage is confirmed by in/ex-situ measurements and DFT calculations. This research has taken an important step toward the development of high-performance energy storage electrode materials. image

Atomically Asymmetrical Ir-O-Co Sites Enable Efficient Chloride-Mediated Ethylene Electrooxidation in Neutral Seawater SCIE
期刊论文 | 2024 , 64 (5) | ANGEWANDTE CHEMIE-INTERNATIONAL EDITION
Abstract&Keyword Cite

Abstract :

The chloride-mediated ethylene oxidation reaction (EOR) of ethylene chlorohydrin (ECH) via electrocatalysis is practically attractive because of its sustainability and mild reaction conditions. However, the chlorine oxidation reaction (COR), which is essential for the above process, is commonly catalyzed by dimensionally stable anodes (DSAs) with high contents of precious Ru and/or Ir. The development of highly efficient COR electrocatalysts composed of nonprecious metals or decreased amounts of precious metals is highly desirable. Herein, we report a modified Co3O4 with a single-atom Ir substitution (Ir-1/Co3O4) as a highly efficient COR electrocatalyst for chloride-mediated EOR to ECH in neutral seawater. Ir-1/Co3O4 achieves a Faradaic efficiency (FE) of up to 94.8 % for ECH generation and remarkable stability. Combining experimental results and density functional theory (DFT) calculations, the unique atomically asymmetrical Ir-O-Co configuration with a strong electron coupling effect in Ir1/Co3O4 can accelerate electron transfer to increase the reaction kinetics and maintain the structural stability of Co3O4 during COR. Moreover, a coupling reaction system integrating the anodic chloride-mediated and cathodic H2O2-mediated EOR show a total FE of similar to 170 % for paired electrosynthesis of ECH and ethylene glycol (EG) using ethylene as the raw material. The technoeconomic analysis highlights the promising application prospects of this system.
