| 英文摘要 | Carbonaceous particles, as one of the main sources of atmospheric aerosols, have great influence on the climate change, such as ice formation, precipitation and polar ice melting. Because sulphur-containing emissions can significantly affect the chemical compositions and properties of carbonaceous particles through various aging processes, it is critical to investigate the influence of sulphur-doped carbon materials on ice formation. Here, we synthesized a sulphur-doped carbon nanomaterial-sulphur-doped oxidized quasi-carbon nitride quantum dots (S-OCNQDs), and investigated the influence of chemical structure on ice growth and recrystallization. The experimental results show that the S-OCNQDs can inhibit ice growth/recrystallization. In addition, we found that forming more hydrogen-bonds with ice contributes to enhancing the efficiency of ice growth/recrystallization inhibition and that heteroatom-doping is a promising way to regulate the ice growth/recrystallization. This work correlates the specific chemical structures of carbon nanomaterials with their performance in inhibiting ice growth/recrystallization through their density of hydrogen-bonds formed with ice. It is instructive for understanding the effect of sulphur-doping on ice formation as well as the design of efficient anti-icing materials. (C) 2017 Elsevier Ltd. All rights reserved. |
