However, the limited number of available Zn storage sites, i.e., limited capacity, hinders its application because the inserted Zn²⁺, which form strong electrostatic interactions with 1T-MoS₂, preventing subsequent Zn²⁺ insertion. Currently, the approach of enlarging the interlayer distance to reduce electrostatic interactions has been commonly used to enhance the capacity and reduce Zn²⁺ migration barriers. However, an enlarged interlayer spacing can weaken the van der Waals force between 1T-MoS₂ monolayers, easily disrupting the structural stability. Herein, to address this issue, an effective strategy based on Fe doping is proposed for 1T-MoS₂ (Fe-1T-MoS₂). The theoretical calculations reveal that Fe doping can simultaneously moderate the rate of decrease in the adsorption energy after gradually increasing the number of stored atoms, and enhance the electron delocalization on metal-O bonds. Therefore, the experiment results show that Fe doping can simultaneously activate more Zn storage sites, thus enhancing the capacity, and stabilize the structural stability for improved cycling performance. Consequently, Fe-1T-MoS₂ exhibits a larger capacity (189 mAh·g⁻¹ at 0.1 A·g⁻¹) and superior cycling stability (78% capacity retention after 400 cycles at 2 A·g⁻¹) than pure 1T-MoS₂. This work may open up a new avenue for constructing high-performance MoS₂-based cathodes.</p><h3>Graphical abstract</h3>\u0000<div><figure><div><div><picture><source><img></source></picture></div></div></figure></div></div>","PeriodicalId":749,"journal":{"name":"Rare Metals","volume":"44 1","pages":"253 - 263"},"PeriodicalIF":9.6,"publicationDate":"2024-08-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142209198","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Besides the modification of the electronic structure of the catalysts, external factors such as visible light irradiation can improve the efficiency of hydrogen production as well. In the present study, a <i>Z</i>-scheme heterostructured V_O–Cu_0.5Ni_0.5O catalysts were constructed by introducing a plenteous phase interface and oxygen vacancy (Vo). The catalytic activity of as-prepared V_O–Cu_0.5Ni_0.5O toward AB methanolysis has been improved dramatically with the assistance of visible light irradiation. The turnover frequency (TOF) under visible light irradiation was measured to be 29 mol_H2·mol_cat.⁻¹·min⁻¹, which is 1.4 times larger than the TOF in the absence of visible light. Systematic characterization experiments and density functional theory (DFT) calculations were conducted to unveil the causation of enhanced catalytic activity. The results demonstrated that the enhancement of the catalytic activity of V_O–Cu_0.5Ni_0.5O originated from the electronic structure modification induced by the formation of heterojunctions, the introduction of oxygen vacancies, and the assistance of visible light cooperatively. The formation of heterojunction and the introduction of oxygen vacancies provoked the upshift of the d-band center; while the visible light irradiation induced the photogenerated electrons to transfer from Cu to Ni sites at the interface. Such electron structure modulation is beneficial for the construction of abundant active sites, thereby enhancing the adsorption of methanol on the Ni sites, which is considered as the rate-determine step for the methanolysis of AB. The strong interaction between Ni and O weakened the O–H bond of methanol, accelerating the methanolysis of AB. These results demonstrate the utilization of combined heterojunction, oxygen vacancy, and visible light to explore highly active AB methanolysis catalysts, which should shed light on the exploration of more effective catalysts for AB methanolysis.</p><h3>Graphical Abstract</h3>\u0000<div><figure><div><div><picture><source><img></source></picture></div></div></figure></div></div>","PeriodicalId":749,"journal":{"name":"Rare Metals","volume":"44 1","pages":"389 - 403"},"PeriodicalIF":9.6,"publicationDate":"2024-08-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142209192","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, developing effective bifunctional electrocatalysts capable of driving the hydrogen evolution reaction (HER) and oxygen evolution reaction (OER) remains a formidable challenge. Addressing this, we introduce a novel built-in electric field (BEF) strategy to synthesize NiCoP–Co nanoarrays directly on Ti₃C₂T_<i>x</i> MXene substrates (NiCoP–Co/MXene). This approach leverages a significant work function difference (Δ<i>Φ</i>), propelling these nanoarrays as adept bifunctional electrocatalysts for comprehensive water splitting. MXene, in this process, plays a dual role. It acts as a conductive support, enhancing the catalyst’s overall conductivity, and facilitates an effective charge transport pathway, ensuring efficient charge transfer. Our study reveals that the BEF induces an electric field at the interface, prompting charge transfer from Co to NiCoP. This transfer modulates asymmetric charge distributions, which intricately control intermediates’ adsorption and desorption dynamics. Such regulation is crucial for enhancing the reaction kinetics of both HER and OER. Furthermore, under oxidative conditions, the NiCoP–Co/MXene catalyst undergoes a structural metamorphosis into Ni(Co) oxides/hydroxides/MXene, increasing OER performance. This research demonstrates the BEF’s role in fine-tuning interfacial charge redistribution and underscores its potential in crafting more sophisticated electrocatalytic designs.

Combining the Pourbaix diagram and phase diagram of Zn-Mn–O with experiment results, the essential energy storage behavior of MnO cathode can be explained as follows: (1) Zn²⁺ insertion/extraction into ZnMn₂O₄ derived from MnO-based active material, and (2) Zn²⁺ insertion/extraction into ZnMn₂O₄ (originated from the transition of Mn²⁺ → Zn₂Mn₃O₈ → ZnMn₂O₄ in the electrolyte).

This paper proposes a novel transformer-embedded lithium-ion battery model for joint estimation of state-of-charge and state-of-health. The battery model is formulated across temperatures and aging, which provides accurate feedback for unscented Kalman filter-based SOC estimation and aging information. The open-circuit voltages (OCVs) are corrected globally by the temporal convolutional network with accurate OCVs in time-sliding windows. Arrhenius equation is combined with estimated SOH for temperature-aging migration. A novel transformer model is introduced, which integrates multiscale attention with the transformer’s encoder to incorporate SOC-voltage differential derived from battery model. This model simultaneously extracts local aging information from various sequences and aging channels using a self-attention and depth-separate convolution. By leveraging multi-head attention, the model establishes information dependency relationships across different aging levels, enabling rapid and precise SOH estimation. Specifically, the root mean square error for SOC and SOH under conditions of 15 °C dynamic stress test and 25 °C constant current cycling was less than 0.9% and 0.8%, respectively.
