| 1 | Current Trends in Pickering Emulsions: Particle Morphology and Applications显示文摘In recent years,Pickering emulsions and their applications have attracted a great deal of attention due to their special features,which include easy preparation and enhanced stability.In contrast to classical emulsions,in Pickering emulsions,solid microparticles or nanoparticles that localize at the interface between liquids are used as stabilizers,instead of surfactants,to enhance the droplet lifetime.Furthermore,Pickering emulsions show higher stability,lower toxicity,and stimuli-responsiveness,compared with emulsions that are stabilized by surfactants.Therefore,they can be considered attractive components for various uses,such as photocatalysis and the preparation of new materials.Moreover,the nanoparticle morphology strongly influences Pickering emulsion stability as well as the potential utilization of such emulsions.Here,we review recent findings concerning Pickering emulsions,with a particular focus on how the nanoparticles morphology(i.e.,cube,ellipsoid,nanosheet,sphere,cylinder,rod,peanut)influences the type and stability of such emulsions,and their current applications in different fields such as antibacterial activity,protein recognition,catalysis,photocatalysis,and water purification. | Danae Gonzalez Ortiz Celine Pochat-Bohatier Julien Cambedouzou Mikhael Bechelany Philippe Miele | 2020 | Engineering2020，6，4： | 22 |

| 7 | TiO_2–SA–Arg nanoparticles stabilized Pickering emulsion for photocatalytic degradation of nitrobenzene in a rotating annular reactor显示文摘Pickering emulsions stabilized by salicylic acid and arginine modified titanium dioxide(Ti O2–SA–Arg) nanoparticles were prepared in this study for photocatalytic degradation of nitrobenzene in a rotating annular reactor,and the effects of various design parameters of the rotating annular reactor, initial nitrobenzene concentration,catalyst amount, and solution p H on the degradation rate of nitrobenzene were investigated. Meanwhile, the degradation mechanism of nitrobenzene was proposed. The results show that increasing the aeration rate, the rotational speed, and light intensity results in a higher photocatalytic degradation rate of nitrobenzene owing to the effective clearance of electrons and a high quantity of oxidative free radicals. The degradation of nitrobenzene in the rotating annular reactor follows the pseudo first-order kinetics, but it is not well described by the Langmuir–Hinshelwood equation. Aeration has a significant effect on the photocatalytic degradation pathway of nitrobenzene. Because nitrobenzene can undergo reduction reaction as electron acceptors and oxidative degradation initiated by hydroxyl free radicals, the photocatalytic degradation of nitrobenzene follows the reduction mechanism under no aeration, but the oxidation mechanism under aeration. | Shiguang Zhang Lei Li Youzhi Liu Qiaoling Zhang | 2017 | Chinese Journal of Chemical Engineering2017，25，2： | 2 |
| 8 | One-dimensional titania nanotubes annealed at various temperatures for the photocatalytic degradation of low concentration gaseous pollutants显示文摘In this study,one-dimensional titania nanotubes(TNTs) were synthesized using a combined process of chemical and hydrothermal treatments,and their activities for the photocatalytic reactions of selected gaseous pollutants at sub-ppm levels were determined.Additionally,the properties of the TNTs were examined using selected spectroscopic methods.The annealed TNTs showed higher photocatalytic activities for the four target compounds than did the unannealed TNTs.For all the target compounds except benzene,the effect of the annealing temperature on the degradation efficiency was difficult to determine because all degradation efficiencies were very high.However,for benzene,which decomposed with a low efficiency,the degradation activities of the TNTs increased as the treatment temperature was increased from 250 to 300 ℃,while they decreased slightly when the temperature was increased from 300 to 400 ℃.These findings confirm the presence of an optimal annealing temperature for the synthesis of TNTs.Moreover,the average degradation extents for benzene,toluene,ethylbenzene,and o-xylene decreased from92%,96%,99%,and 98%to 77%,86%,92%,and 94%,respectively,as the airstream flow rate increased within the range of 1-4L/min.The average degradation extents decreased from 12%,75%,87%,and 88%to 3%,29%,46%,and 51%,respectively,as the input concentration increased from 0.4 to 1.9 ppm.Overall,these findings suggest that one-dimensional TNTs can be effectively utilized for the degradation of gaseous pollutants under optimal operational conditions. | Ho-Hwan Chun Wan-Kuen Jo | 2015 | Particuology2015，13，2： | 1 |
| 9 | 芳香族硝基化合物废水处理的研究进展显示文摘芳香族硝基化合物中的硝基苯、硝基甲苯、二硝基苯酚等都是炸药的主要成分,除了它们本身的爆炸性和危险性,还具有高稳定性及高毒性,对人类健康、土壤、水源及生态环境都会造成极大的危害。本研究介绍了目前芳香族硝基化合物废水处理技术的现状,依据物理处理、化学处理和生物降解三种处理方法,进行了各种技术优缺点的总结,并展望了发展趋势。三种处理方法中物理处理法存在潜在的二次污染风险,生物降解法时间成本较高,故认为化学处理法是最具发展前景的方法,其中的光催化法仅借助太阳光就可高效降解芳香族硝基化合物废水,具有绿色环保、节能等优点,虽该方法还未运用到实际应用中,但可将其他处理技术与光催化法联合应用,达到取长补短、相得益彰的效果。 | 唐婷婷 赵平 金波 | 2022 | 含能材料2022，30，10： | 1 |
