However, it faces the problems of easy compounding and instability. Therefore, we designed and synthesized Fe-Cu/TiO₂ composite catalysts and constructed a synergistic photocatalytic-persulfate degradation system. The phenol (50 ppm) degradation efficiency of 70 % Fe-Cu/TiO₂ was 97.3 % after 30 min of reaction, which was 1.49 and 16.51 times greater than those of Fe-Cu and TiO₂, respectively. This was attributed to the fact that mixing TiO₂ and Fe-Cu not only effectively promoted Fe-Cu dispersion but also improved the number of active sites and catalytic degradation activity. Moreover, the photogenerated electrons generated by TiO₂ could promote the valence transition between Fe-Cu, slowly releasing Fe²⁺ and Cu⁰ to realize the continuous activation of PDS and enhance the degradation activity. Quenching experiments and EPR results showed that the catalytic degradation process was dominated by the nonradical ¹O₂, with SO₄·^-, ·OH and ·O₂^- radicals interacting synergistically. Based on the characterization and experimental results, a synergistic degradation mechanism of Fe-Cu/TiO₂ was proposed, which provides a new approach for pollutant degradation.</div></div>","PeriodicalId":22081,"journal":{"name":"Surfaces and Interfaces","volume":null,"pages":null},"PeriodicalIF":5.7,"publicationDate":"2024-10-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142571613","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}

Addition of Cr shows a significantly improved degradation efficiency from 20% to 91% in just 25 min for CR, while the degradation rate reached to 81% for TC, which was also monitored in real-time using internet of things (IoT).

This substitution causes a continuous increase in the concentration of charge carriers and a reduction in electron mobility.

Currently, the electrocatalytic transformation of N₂ and CO₂ into urea is a promising strategy. However, finding a high-selectivity and high-activity catalyst remains a significant challenge. Herein, the activity of a series of transition metal clusters (VIII and IB groups) on copper-based catalysts for electrochemical coupling of CO₂ and N₂ has been systematically studied to produce urea via density functional theory (DFT). Most catalysts exhibit good thermodynamic stability and accomplish co-adsorb CO₂ and N₂. Notably, Fe3 and Ni3/Cu100 catalysts achieve C-N coupling via *CO and *N₂, whereas Ru3, Rh3, Os3, and Ir3/Cu100 catalysts accomplish C-N coupling via *CO and *NHNH. Among all catalysts, the Ni3/Cu100 catalyst features excellent catalytic activity with a rate-determining step as low as 0.480 eV, and its C-N coupling only needs to overcome a barrier of 0.844 eV. Additionally, the Ni3/Cu100 catalyst can effectively inhibit the hydrogen evolution reaction (HER), further protonation of *CO and ammonia formation, thereby ensuring high selectivity for urea. Electronic structures analysis further reveals an “acceptance-donation” mechanism for the activation of *CO₂ and *N₂, with the introduction of the Ni3 cluster showing a decisive role.

A superhydrophilic surface was initially fabricated on the stainless steel disc by laser marker ablation allowing 1 μL droplet to spread completely to 0° within 0.12 s, followed by fluorine-containing coating transforming superhydrophilic surface to superhydrophobic one. Directional water transport patterns were then etched on the superhydrophobic surfaces by the secondary laser marker. The surface energy gradient and Laplace pressure induced by the pattern facilitated directional fast transport and efficient desorption of droplets, thus improving water collection efficiency. The enhancement mechanism of the water harvesting behavior for such surfaces was analyzed, with one focus on enhancing collection in hydrophobic regions with capillaries to reduce bouncing off loss and the other on improving balanced cycling of the collection process. At a fog flow rate of 1500 ml/h and 20 cm away from the fog outlet, the directional leaf vein-patterned 19.625 cm² sized surface demonstrated a fog water collection rate (WCR) of 5.6 Kg·m^-2·h^-1 and first drop collection at the 49th s, an impressively short time rarely reported.

However, the morphology evolution mechanism of the micro-pillars is not clear during polishing, which seriously affects the rapid preparation of high-quality MLAs. Herein, a multi-physics coupling model is established to investigate the interaction between CO₂ lasers and micro-pillars on the fused silica surface, and is verified from the perspectives of temporal and spatial temperature. The steady surface temperature evolution law with laser power and spot radius is explored, based on which, the parameter ‘Window’ for polishing is determined to make the material melt and flow without ablation removal. The morphology evolution of micro-pillars is investigated as well as laser-material interaction. It is found that under laser irradiation, the micro-pillar height first increases and then decreases, and its top curvature radius increases. The surface tension makes the dominant contributions to the melting and flow of the micro-pillar materials, while the Marangoni effect and the gravity have little effect. Furthermore, to fabricate the target MLAs with the specific dimensions, the influence of micro-pillar aspect ratio (<em>φ</em>) on microlens surface morphology is investigated. It is found that there are two critical <em>φ</em> for the target MLAs. For the required MLA with the target period of 200 μm and the target height of 40 μm, when the <em>φ</em> is larger than 5.1, the micro-pillar array fails to be shaped into the target MLA by CO₂ laser polishing. As the <em>φ</em> decreases, the junction of micro-pillar and the substrate sags downwards significantly, and the deviation between the shaped- and the ideal spherical contours increases. To successfully prepared the target MLA and guarantee the geometry accuracy, the minimum <em>φ</em> is selected to be 0.71.
