Here, we prepared RuNC, a Ru nanoclusters catalyst anchored on CeO₂ with strong metal-support interaction (SMSI) effect via a facile preparation method. The formation rates of H₂ and CO over RuNC catalyst were 1.41 and 2.16 mol·gcat⁻¹·h⁻¹ respectively under photo-thermal catalysis (PTC) at 500 °C, which is up to one order of magnitude higher than existing PTC-MDR catalysts.

Conventional batteries are unable to guarantee a reliable power supply for LWD operations in extreme high-temperature conditions encountered at depths exceeding 10,000 m. Moreover, the development of dedicated batteries for these applications is progressing at a relatively slow pace. In light of these considerations, we put forth a novel proposal: a composite solid-state electrolyte (CSE) for HLB. Poly (ether ether ketone) (PEEK) nanofiber membranes, which are thermally stable at temperatures exceeding 350 °C, were prepared and subsequently composited with Li₇La₃Zr₂O₁₂ (LLZO) by the vacuum filtration method. At room temperature, the PEEK-LLZO composite exhibits ionic conductivity of 1.11 mS·cm ⁻¹ and demonstrates stability in lithium-lithium symmetric cells for up to 3500 h. The initial discharge specific capacity was recorded at 132.9 mAh·g ⁻¹ at 0.5 C rate, declining to 86.6 % after 500 cycles. Density Functional Theory (DFT) simulations were employed to elucidate the lithium-ion transport mechanisms within the CSE system. It is noteworthy that the CSE displays remarkable thermal stability, with a performance threshold exceeding 300 °C. The ionic conductivity of the CSE system reaches 2.40 mS·cm ⁻¹ at 250 °C, representing a twofold increase compared to the LLZO system and an elevenfold increase compared to the LiTFSI molten salt system. Moreover, the initial discharge specific capacity of the CSE was determined to be 123.3 mAh·g ⁻¹ at 250 °C and a 1 C rate, retaining 92.8 % of its capacity after 50 cycles. These findings suggest that the CSE exhibits high safety, excellent cycling stability, and considerable potential for application in high-temperature lithium-ion batteries.</div></div>","PeriodicalId":394,"journal":{"name":"Nano Energy","volume":"133 ","pages":"Article 110475"},"PeriodicalIF":16.8,"publicationDate":"2024-11-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142601673","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Soft-soft contact was achieved utilizing soft Ecoflex foam film and soft spring steel sheet. A microsphere structured surface was constructed on the Ecoflex film through foaming technology, which increases the surface charge density of the triboelectric materials effectively. Accordingly, the open-circuit voltage of triboelectric materials can reach up to 1700 V.
