In this study, we investigate the crystallographic plane interactions between nickel oxide (NiO) and a modified ceria-zirconia-praseodymium oxide support (CeZrPrOx) to elucidate their influence on catalytic activity in methane dry reforming. X-ray diffraction (XRD) patterns and transmission electron microscopy (TEM) techniques were employed to characterize the catalyst. Our findings reveal that specific crystallographic planes significantly impact the catalytic performance of NiO/CeZrPrOx catalyst. The (111), (110), and (100) facets of the support material are examined for their interactions with NiO. We observe that the (110) plane of the support exhibits strong interaction with NiO, leading to enhanced catalytic activity. This interaction facilitates superior anchoring of Ni nanoparticles, lowering sintering and promoting a strong metal-support interaction effect (SMSI). Additionally, our analysis suggests that the (110) interface is particularly favorable for methane dry reforming. Overall, this study highlights the importance of crystallographic plane interactions in NiO/CeZrPrOx catalysts and offers valuable insights for optimizing catalyst design for methane conversion processes.</div></div>","PeriodicalId":100957,"journal":{"name":"Next Energy","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-10-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142446508","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}

Most of its properties have been reported for monocrystals or polycrystalline thick films used in high-energy photon detectors. As for thin films used in other optoelectronic devices, the reported properties are limited to the conditions adopted in manufacturing the devices. Furthermore, very little is known about the properties of films deposited by sputtering. Here, we investigate the optical and structural properties of PbI₂ thin films deposited by rf-sputtering a PbI₂ target. The deposition temperature significantly influences the film's properties, as determined by X-ray, scanning electron microscopy (SEM), atomic force microscopy (AFM), UV-vis, and Raman spectroscopy. A common characteristic at all temperatures was forming metallic lead (Pb) segregated in the surface of films, with concentration depending on the deposition temperature. These lead clusters were successfully converted into PbI₂ using an iodination process, allowing the synthesis of pure PbI₂ films without lead segregation. The activation energy for the reaction between Pb clusters and iodine vapor was determined by adopting the Arrhenius equation. It was also observed that converting PbI₂ film into perovskite through the two-step process, by immersion of the PbI₂ film into methylammonium iodide solution, transforms the segregated lead into perovskite. The sputtering technique allows the deposition of uniform films over large areas compatible with roll-to-roll processes, which are desired to produce large-area detectors and perovskite solar cells.</p></div>","PeriodicalId":100957,"journal":{"name":"Next Energy","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-09-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2949821X24000978/pdfft?md5=94101108e2d219edac9769b356ca848b&pid=1-s2.0-S2949821X24000978-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142243350","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}
