However, absolute g-C₃N₄ is inherently scarce in Lewis base sites, which leads to low catalytic activities. In this study, we present a simple and green method to in situ construct chrysanthemum stalk-derived porous carbon/ highly active defective g-C₃N₄ (PC/g-C₃N₄) through hydrogen bond, increasing the surface area and a high density of Lewis base sites. The chrysanthemum stalk contains cellulose, hemicellulose and lignin, which possess a significant number of hydroxyl functional groups and drain channels, thereby providing more hydrogen bonding for highly active defective g-C₃N₄. The XPS spectra revealed that, in comparison to PC/g-C₃N₄–1 and PC/ g-C₃N₄–2.5, PC/g-C₃N₄–2 exhibited a higher C-NH₂ content at the edge of the nitrogen element. PC/g-C₃N₄–2 had a high specific surface area to expose more active sites for absorbing CO₂. The quantification of the base sites is determined by the peak area of the thermal programmed desorption of CO₂ and is 229.6 μmol/g for PC/g-C₃N₄–2. PC/g-C₃N₄–2 demonstrated excellent catalytic activity in the cycloaddition with hierarchical pores. The yield of cyclic carbonate was up to 99% with a selectivity of 99% under mild solvent-free conditions. The mechanistic studies indicate that PC/g-C₃N₄–2 not only captured CO₂, but also provided hydrogen bonds to activate the oxygen atom of epichlorohydrin (ECH). It is our contention that the multifunctional organic-inorganic hybrid materials have considerable potential for the production of cyclic carbonate.</div></div>","PeriodicalId":22081,"journal":{"name":"Surfaces and Interfaces","volume":"56 ","pages":"Article 105537"},"PeriodicalIF":5.7,"publicationDate":"2024-11-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142743545","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study initially reveals substantial differences in thermal conduction capabilities between Si/Diamond, SiC/Diamond, and Diamond/Diamond interfaces. Further investigations focus on interfaces between different structures of SiC and diamond, clearly identifying the atomic composition and structure at the interface as key factors influencing thermal boundary conductance (TBC). Based on these findings, the study proposes a strategy for atomic transition that involves inserting SiC into the Si/Diamond interface. Under optimal thickness conditions for the SiC transition layer, a significant increase in theoretical TBC is achieved, from 477.1 MW/m²K to 701.1 MW/m²K, which is twice the value predicted by the existing diffusive mismatch model (DMM) for Si/Diamond interfaces. Lastly, through the developed 3D IC model, the study examines the impact of TBC variations on the peak temperature of the entire device, thereby further emphasizing the importance of enhancing interface thermal conduction capabilities.

The results revealed that micro-scale droplets exhibit markedly distinct morphological evolution during spreading, contraction, and rebound compared to millimeter-scale droplets. As droplet size decreases, the minimum rebound velocity threshold significantly increases, contact time extends substantially, and viscous dissipation becomes the primary energy loss mechanism in micro-scale droplets, resulting in a dramatic decrease in the restitution coefficient.
