Here, we develop an X-ray Photoelectron Spectroscopy (XPS) that allows for operando measurement during cycling. Based on theoretical analysis and the modulated electrode and detector co-grounding mode, the displacement of binding energy can be correlated with the surface electrostatic potential of the material, revealing the charge distribution and composition evolution of the space charge layer between the cathode and the electrolyte. In the investigation of typical LiCoO₂ (LCO)/Li₆PS₅Cl (LPSC)/Li–In batteries, we observed the static potential difference and oxidative decomposition between LPSC and LCO, and the effectiveness of the LiNbO₃ coating in reducing potential difference and inhibiting the diffusion of Co and oxidation of S species. Furthermore, our study also revealed that the potential drop between LiNi_0·8Co_0·1Mn_0·1O₂ and LPSC is smaller than that of LCO, whilst that between Li₃InCl₆ and LCO remains near zero. The proposed operando XPS method offers a novel approach for real-time monitoring of interface potential and species formation, providing rational guidance for the interface engineering in SSBs.</p></div>","PeriodicalId":7283,"journal":{"name":"Advanced Powder Materials","volume":"3 3","pages":"Article 100184"},"PeriodicalIF":0.0,"publicationDate":"2024-02-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2772834X24000150/pdfft?md5=b791a8d0f81ff38dcb4e2a38f33e058b&pid=1-s2.0-S2772834X24000150-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140163954","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this work, a chemically bonded Mn_0.5Cd_0.5S/BiOBr S-scheme heterostructure with oxygen vacancies is ingeniously developed through a facile <em>in-situ</em> solvothermal synthesis. The designed Mn_0.5Cd_0.5S/BiOBr heterojunction exhibits eminently reinforced photo-activity for destruction of tetracycline hydrochloride and Cr(VI) as compared with its individual components. This substantial photo-redox performance amelioration is benefitted from the creation of an intense internal electric field (IEF) via supplying powerful driving force and migration highway by interfacial chemical bond to foster the S-scheme electron/hole disintegration. More intriguingly, the IEF at the hetero-interface drives the fast consumption of the photo-induced holes in Mn_0.5Cd_0.5S by the photoelectrons from BiOBr, profoundly boosting the enrichment of active photo-carriers and sparing the photo-corrosion of Mn_0.5Cd_0.5S. Furthermore, Mn_0.5Cd_0.5S/BiOBr with exceptional anti-interference property can work efficiently in real water matrices. Multiple uses of the recycled Mn_0·5Cd_0·5S/BiOBr evidence its prominent robustness and stability.
