Accelerated Formation of H2 Nanobubbles from a Surface Nanodroplet Reaction
摘要：
液滴内化学反应的区室化具有低成本、减少试剂消耗和增加通量的优点。小液滴中的反应也被证明可以大大加快许多化学反应的速度。在这项工作中，从纳米液滴反应的纳米气泡的加速生长速率证明。来自纳米液滴表面处的反应的气态产物促进多个有机液体纳米液滴内的氢纳米气泡的成核。纳米气泡被限制在液滴内，并在液滴周边选择性地生长和塌陷，如通过具有高空间和时间分辨率的显微镜观察到的。气泡的生长速率在小液滴内显著加快，并与液滴半径成反比。加速归因于液滴体积的限制和表面积对用于气体产生的界面化学反应的影响。这项研究的结果提供了进一步的理解，在液滴增强生产的纳米气泡和按需释放氢气的应用。
英文摘要：
The compartmentalization of chemical reactions within droplets has advantages in low costs, reduced consumption of reagents and increased throughput. Reactions in small droplets have also been shown to greatly accelerate the rate of many chemical reactions. The accelerated growth rate of nanobubbles from nanodroplet reactions is demonstrated in this work. The gaseous products from the reaction at the nanodroplet surface promoted nucleation of hydrogen nanobubbles within multiple organic liquid nanodroplets. The nanobubbles were confined within the droplets and selectively grew and collapsed at the droplet perimeter, as visualized by microscopy with high spatial and temporal resolutions. The growth rate of the bubbles was significantly accelerated within small droplets and scaled inversely with droplet radius. The acceleration was attributed to confinement from the droplet volume and effect from the surface area on the interfacial chemical reaction for gas production. The results of this study provide further understanding for applications in droplet enhanced production of nanobubbles and the on-demand liberation of hydrogen.
