However, the full potential of metal-halide perovskite nanocrystals remains untapped. In this study, we synthesised a series of CsPbBr₃ nanowires with tailorable tensile strain (0%-1%) through a strain engineering approach to enhance photocatalytic CO₂ reduction performance. Nanowires with moderate strain (0.47%) attained superior catalytic performance with an electron consumption rate exceeding 300 μmol g^-1 h^-1 and 100% selectivity for CO production, surpassing that of the unstrained sample by five times. Ultrafast spectroscopy, in-situ diffuse reflectance infrared Fourier transform spectroscopy, and density functional theory calculations revealed that the enhanced performance of the strained sample arises from strain-modulated polaron formation, which retards the carrier decay process (with the longest time component increasing from 672 ps to 2.85 ns), as well as strain-tailored electronic structures that lower the thermodynamic energy barrier for *COOH formation. Our study highlights the significance of strain-modulated polaron behaviour in metal-halide perovskite photocatalysts.</p>","PeriodicalId":421,"journal":{"name":"Science Bulletin","volume":" ","pages":""},"PeriodicalIF":18.8,"publicationDate":"2025-06-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144525849","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"综合性期刊","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Exampled by the representative Na₃V₂(PO₄)O₂F (NVPOF) with considerable theoretical energy density, structural distortion results in a one-dimensional sluggish Na⁺ diffusion out of the two-dimensional Na⁺ pathway provided structurally. Previous endeavors with Na site or transition-metal site regulation successfully optimize the Na⁺ diffusion energy barrier of the available one-dimensional path. However, these substituted elements with non-equivalent valances or sizes further elevate the energy barrier of the other unavailable Na⁺ diffusion path. Herein, by defining the independently accessible Na⁺ diffusion pathways in the crystallographic structure as Na⁺ diffusion degree of freedom (df_[Na+]), we demonstrate broadening df_[Na+] to two in NVPOF by a mild perturb at the dangling site can fundamentally revise the Na⁺ diffusion behaviour. As demonstrated by in-situ synchrotron, various spectroscopic techniques, and density functional theory (DFT) modeling, this mild perturb equalizes the Na⁺ diffusion energy barriers along a and b directions and enables two-dimensional Na⁺ transportation. The as-prepared NVPOF depicts an altered solid-solution phase transition, higher disorder in the framework and dramatically enhanced Na⁺ diffusivity, which leads to unprecedentedly high sodium storage properties in half cell (68.6 mAh g^-1 at 100 C; 103.3 mAh g^-1 after 1300 cycles at 20 C; 1 C = 130 mA g^-1) and full cell (313.8 Wh kg^-1@4063.5 W kg^-1; 113.9 Wh kg^-1@16,397.2 W kg^-1). This study enlightens the valuable role of broadening df_[Na+] in fundamentally maximizing the polyanionic insertion-type performance.</p>","PeriodicalId":421,"journal":{"name":"Science Bulletin","volume":" ","pages":""},"PeriodicalIF":18.8,"publicationDate":"2025-06-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144525846","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"综合性期刊","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
