Ga was doped into the γ-Al₂O₃ lattice at a low concentration, forming interfacial active sites with surface Cu⁰ species to achieve the hydrogenation of CO₂ to DME.

Its effectiveness relies on three critical steps: atomic hydrogen (H∗) generation, C-Cl bond cleavage, and adsorption/desorption of CAHs/products. Developing high-performance electrocatalysts is essential to optimize energy efficiency and cost-effectiveness. It is urgent to summarize research progress on design strategies for catalysts and establish fundamental principles. In this review, we first summarize commonly deployed measurement methods and metrics for assessing catalyst activity and stability in EHDC. Then, a series of strategies for enhancing the production of H∗, facilitating the cleavage of C-Cl bonds, and optimizing the adsorption and desorption kinetics of CAHs and their intermediates/products on the catalyst surface are summarized. These strategies include the loading of catalysts on carbon-based/transition-based support to enhance the dispersion of Pd; constructing heterostructures or forming alloys to modulate the electronic structure of active metal nanocatalysts and optimize its binding affinities with reactants and intermediates; and modulating the microenvironment to modify the interface hydrophilicity/hydrophobicity of catalyst to increase reaction rates or improve stability of catalysts. Additionally, the applications of electrocatalysts for EHDC in recent years, such as Pd-based supported electrocatalysts, Pd-based heterostructure electrocatalysts, Pd-based alloy electrocatalysts, and noble-metal-free electrocatalysts are discussed, as well as the influence of catalyst composition on performance. It is noted that the EHDC efficiency of CAHs is influenced not only by the catalyst but also significantly correlated with the structure of CAHs. Thus, the effects of CAHs structures on EHDC performance are also discussed. Studies demonstrate that weak adsorption between the electrode and CAHs is more conducive to EHDC reactions. The number and position of chlorine functional groups, steric hindrance, and the properties of other functional groups in the substrate molecule can also influence EHDC performance. Finally, the challenges and future prospects of EHDC are highlighted, including improving the catalytic performance of non-noble catalysts, employing advanced in situ and operando characterization techniques, and optimizing DFT calculations to more closely align with real catalytic conditions, all aiming to inspire new investigations and advancements in the field of EHDC of CAHs.</div></div>","PeriodicalId":6964,"journal":{"name":"物理化学学报","volume":"41 10","pages":"Article 100120"},"PeriodicalIF":10.8,"publicationDate":"2025-06-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144472381","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the complex multi-physics reactions within batteries make traditional mathematical models inadequate for comprehensively revealing their mechanisms. The key to solving this problem lies in introducing data-driven approaches, which have laid a solid foundation for battery research and development through extensive accumulation of experimental data and extraction of effective information. Generative artificial intelligence (GAI), leveraging its powerful latent pattern learning and data generation capabilities, has already found widespread applications in protein structure prediction, material inverse design, and data augmentation, demonstrating its broad application prospects. Applying GAI to battery research workflows with diverse battery data resources could provide innovative solutions to challenges in battery research. In this perspective, we introduce the core principles and latest advancements of generative models (GMs), including Generative Adversarial Network (GAN), Variational Auto-Encoder (VAE), and Diffusion Model (DM), which can learn the latent distribution of the input samples to generate new data by sampling from it. Applications of GAI in battery research are then reviewed. For battery materials design, by learning material compositions, structures, and properties, GM can generate novel candidate materials with desired properties through conditional constraints, significantly extending the chemical space to be explored. For electrode microstructure characterization, GM can serve as a bridge for interconversion and integration of different image data, enhance the quality of microscopic characterization, and generate realistic synthetic data. For battery state estimation, GM can perform data augmentation and feature extraction on battery datasets, which benefits the model performance for battery state estimation. Lastly, we discuss the challenges and future development directions in terms of data governance and model design, including data quality and diversity, data standardization and sharing, usability of synthetic data, interpretability of GM, and foundational models for battery research. For the innovation and advancement of battery technology, this perspective offers theoretical references and practical guidelines for implementing GAI as an effective tool in battery research workflows by discussing its status and prospects in this field.</div></div>","PeriodicalId":6964,"journal":{"name":"物理化学学报","volume":"41 10","pages":"Article 100115"},"PeriodicalIF":10.8,"publicationDate":"2025-06-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144472367","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Improving the electric conductivity of activated carbon is crucial for promoting its electrochemical energy storage, but it is hard to achieve because well-developed pores usually break the continuous conductive network. To solve this problem, researchers have developed several methods, such as the selection of highly-conjugated carbon precursors, high-temperature post-treatment, compositing with highly conductive nanocarbons, and local catalytic graphitization. However, these methods generally suffer from high cost, low efficiency, and the sacrifice of specific surface area. Herein, we propose a selective chemical etching strategy to prepare activated carbon with both high surface area and electric conductivity using a mixture of pitch and polyacrylonitrile (PAN) as the precursor. Through systematic investigation of the activation behavior of pure pitch, pure PAN, and the composite precursors, we demonstrate that the PAN-derived carbon contains amorphous and crystallized components. During activation, the amorphous carbon is primarily etched away due to its high reactivity, leading to the in-situ formation of less-defective carbon as the entire conductive network. The optimized sample shows a surface area of 2773 m² g⁻¹ and 2.6 times increased electric conductivity of 912 S m⁻¹, outperforming most of the reported activated carbons. Furthermore, the strong cross-linking between pitch and PAN molecules through pre-oxidation leads to a higher activated carbon yield of 58 % than the pure pitch activated carbon (34 %). The optimized cross-linking structure also allows the activator K⁺ to be adsorbed more easily in the carbon precursor, which enhances the activation efficiency. As a result, the embedded PAN simultaneously constructs a conductive network and promotes activation efficiency, leading to the integration of high electric conductivity and surface area of the activated carbon. For aqueous supercapacitor application, at the high electrode mass loading of 10 mg cm⁻², the optimized material shows remarkable areal capacitance (2.8 F cm⁻² at 1 A g⁻¹) and good rate performance (41 % retention at 50 A g⁻¹). The corresponding device shows high energy densities (10.9 Wh·kg⁻¹) and remarkable cycle stability (100 % retention after 50000 cycles). The reason is that good electric conductivity enables high surface area utilization, significantly improved electric double-layer formation and ion transport kinetics.
