Abstract

Metal nanoparticles have extraordinary properties, but their integration into mesostructures has been challenging. Producing uniformly dispersed nanoparticles attached to substrates in industrial quantities is difficult. Herein, a “plasmashock” method was developed to synthesize metal nanoparticles anchored on different types of carbonaceous substrates using liquid salt solution precursors. These self-supporting, nanoparticle-loaded carbon fabrics are mechanically robust and have been tested as antibacterial substrates and electrocatalysts for reducing carbon dioxide and nitrite. A piece of silver–carbon nanotube paper with a silver loading of ~0.13 mg cm−2 treated after a few-second plasmashock presents good antibacterial and electrocatalytic properties in wastewater, even after 20 bactericidal immersion cycles, due to the strong bonding of the nanoparticles to the substrate. The results prove the effectiveness of this plasmashock method in creating free-standing functional composite films or membranes. A “plasmashock” method was developed to synthesize metal nanoparticles anchored on different kinds of carbonaceous substrates using liquid salt solution precursors. These self-supporting, nanoparticles-loaded carbon fabrics are mechanically robust and tested as antibacterial substrate and electrocatalysts for reducing carbon dioxide and nitrite.

爆发等离子体在碳织物上制备用于抗菌和电催化的金属纳米颗粒

金属纳米颗粒具有非凡的性能，但将其整合到介观结构中一直具有挑战性。工业批量生产均匀分散的纳米颗粒附着在基材上是困难的。本研究开发了一种“等离子冲击”方法，利用液态盐溶液前体合成锚定在不同类型碳基基质上的金属纳米颗粒。这些自我支撑的、纳米颗粒负载的碳织物在机械上是坚固的，并且已经被测试作为抗菌基底和减少二氧化碳和亚硝酸盐的电催化剂。经过几秒等离子体冲击处理后，含银量为~0.13 mg cm−2的银碳纳米管纸在废水中表现出良好的抗菌和电催化性能，即使经过20次杀菌浸泡循环，也能表现出良好的抗菌和电催化性能，这是由于纳米颗粒与衬底的强结合。结果证明了等离子体激波方法在制备独立功能复合薄膜或膜方面的有效性。采用“等离子冲击”方法，利用液态盐溶液前驱体在不同碳质基质上合成金属纳米颗粒。这些自支撑的、纳米颗粒负载的碳织物在机械上是坚固的，并且作为抗菌基质和减少二氧化碳和亚硝酸盐的电催化剂进行了测试。
