The emergence of this class of catalysis is attributable to increasing need for sustainable and ecofriendly pathways to value-added chemical synthesis. The roadmap for the highly diverse and multifaceted field of catalysis continues to evolve, highlighting the growing need of understanding their physical and chemical reaction mechanism. Among the many available characterization techniques, in situ and operando investigations stand out for their ability to provide detailed insights into fundamental physicochemical processes under realistic working conditions. In this article, a select group of representative energy material is discussed, where the application of different in situ/operando techniques successfully generates improved understanding. The primary goal is to emphasize the significance of these techniques, particularly those, which have been commonly employed in studying materials relevant to energy and environmental applications.","PeriodicalId":9819,"journal":{"name":"Chemphyschem","volume":" ","pages":"e2401148"},"PeriodicalIF":2.3,"publicationDate":"2025-06-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144504956","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A previously optimized ZIF-8 synthetic method is employed, and the prepared material is deeply characterized with X-ray powder diffraction (XRPD), surface area analysis, scanning electron microscopy (SEM), and thermogravimetric analysis (TGA). After confirming the successful synthetic outcomes, a tailored loading procedure is developed to incorporate lidocaine within the ZIF-8 pores. The effectiveness of this loading process is verified using UV-Vis spectroscopy and TGA, while SEM and attenuated total reflectance-mid infrared spectroscopy further confirms the presence of lidocaine within the MOF pores. Afterwards, the pH-responsive drug release by dialyzing the lidocaine@ZIF-8 sample is tested either at physiological or at weakly acid pH values by UV spectroscopy on the dialysis solutions. Finally, the MDA-MB-231 breast cancer cells viability of lidocaine@ZIF-8 system is tested and compared with the free drug and the MOF alone, confirming its significant capabilities in the reduction of cells viability.","PeriodicalId":9819,"journal":{"name":"Chemphyschem","volume":" ","pages":"e2401128"},"PeriodicalIF":2.3,"publicationDate":"2025-06-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144483340","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the specific activation and reduction mechanism of CO2 on MXs under realistic electrochemical conditions remain unclear. This study utilizes ab initio molecular dynamics simulations to unravel the kinetic processes of underlying CO2 activation and hydrogenation under aqueous conditions with Mo2C MX as a prototype. These findings reveal that the presence of water molecules significantly enhances the charge transfer of CO2, facilitating its activation on MX. Notably, an insight highlights that the initial hydrogenation of *CO2 on MX prefers to occur on oxygen rather than carbon, favoring the formation of *HOCO over *OCHO. This study proposes that the introduction of alkali metal cations including Li+, Na+, and Cs+ can stabilize the adsorption of CO2 and reaction intermediates on MX via altering the interfacial water structure and hydrogen bonding network and thus effectively inhibiting the competitive hydrogen evolution reaction. Further dynamic vibrational spectra simulations shed light on the interaction between alkaline metal cations and adsorbed CO2 molecules, which will provide a theoretical basis for the in situ detection of reactants. This work provides a deeper insight into the dynamic solid-liquid interface at the atomic level.","PeriodicalId":9819,"journal":{"name":"Chemphyschem","volume":" ","pages":"e2500101"},"PeriodicalIF":2.3,"publicationDate":"2025-06-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144233340","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
