Surface structure degradation has been confirmed as a critical factor contributing to the electrochemical performance deterioration of LMCMs. Herein, we review the recent progress in surface engineering of LMCMs towards next-generation LIBs.

The selective oxidation of dimethyl ether (DME), which is derived from fossil resources, represents a promising approach to producing high-concentration formaldehyde with low energy consumption. However, there is still a lack of catalysts achieving satisfactory conversion of DME with high selectivity for formaldehyde under mild conditions. In this work, an efficient iron-molybdate (FeMo) catalyst was developed for the selective oxidation of DME to formaldehyde. The DME conversion of 84% was achieved with a superior formaldehyde selectivity (77%) at 300 °C, a performance that is superior to all previously reported results. In an approximately 550 h continuous reaction, the catalyst maintained a conversion of 64% and a formaldehyde selectivity of 79%. Combined X-ray diffraction  (XRD), Transmission electron microscope (TEM), Ultraviolet–visible spectroscopy (UV–Vis), Hydrogen temperature-programmed reduction (H₂-TPR), Fourier transform infrared (FT-IR) analyses, along with density functional theory (DFT) calculations, demonstrated that the excellent FeMo catalyst was composed of active Fe₂(MoO₄)₃ and MoO₃ phases, and there was an interaction between them, which contributed to the efficient DME dissociation and smooth hydrogen spillover, leading to a superior DME conversion. With the support of DME/O₂ pulse experiments, in-situ Raman, in-situ Dimethyl ether infrared spectroscopy (DME-IR) and DFT calculation results, a Mars-van Krevelen (MvK) reaction mechanism was proposed: DME was dissociated on the interface between Fe₂(MoO₄)₃ and MoO₃ phases to form active methoxy species firstly, and it dehydrogenated to give hydrogen species; the generated hydrogen species smoothly spilled over from Fe₂(MoO₄)₃ to MoO₃ enhanced by the interaction between Fe₂(MoO₄)₃ and MoO₃; then the hydrogen species was consumed by MoO₃, leading to a reduction of MoO₃, and finally, the reduced MoO₃ was re-oxidized by O₂, returning to the initial state. These findings offer valuable insights not only for the development of efficient FeMo catalysts but also for elucidating the reaction mechanism involved in the oxidation of DME to formaldehyde, contributing to the optimized utilization of DME derived from fossil resources.</div></div>","PeriodicalId":15728,"journal":{"name":"Journal of Energy Chemistry","volume":"106 ","pages":"Pages 832-841"},"PeriodicalIF":13.1,"publicationDate":"2025-03-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143838553","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These inaccuracies hinder the accurate prediction of voltage profiles and overall cell performance. In this study, we propose the characteristic time-decomposed overpotential (CTDO) method, which employs a single-layer particle electrode (SLPE) structure to eliminate interference overpotentials. By leveraging the distribution of relaxation times (DRT), our method effectively isolates the characteristic time of the charge transfer process, enabling a more precise determination of the reaction rate constant. Simulation results indicate that our approach reduces measurement errors to below 2%, closely aligning with theoretical values. Furthermore, experimental validation demonstrates an 80% reduction in error compared to the conventional galvanostatic intermittent titration technique (GITT) method.

Herein, we report a double-protective strategy for cellulose depolymerization and orientated conversion to levulinic acid (LA), one of the important IPCs, by in-situ adding protective formaldehyde (HCHO). This approach initiates from the (hemi)acetalation of hydroxyl groups in cellulose with HCHO, causing controllable depolymerization to (hemi)acetalized glucose with increased rate kinetically and a new mechanism of its catalytic conversion to LA via (hemi)acetal-driven direct C1–C2 cleavage. As such, the cellulose-to-LA conversion is protectively proceeded with the repolymerization of reactive intermediates prevented remarkably, leading to an excellent LA yield of 87.3 mol% from high-loading microcrystalline cellulose (15.0 wt% in aqueous phase) in a biphasic solvent containing 2-methyltetrahydrofuran and water. The process efficiency, expressed as space-time yield, is improved by 3.6 fold when compared with a non-protective approach.
