二氧化碳捕获是一个紧迫的全球环境问题，促使科学家们制定创造性的战略来应对这一挑战。本文的概念是在微孔碳纤维中产生特定位置的氮掺杂。在这种方法之后，通过使用聚（离子液体）（PIL）作为“软”活化剂来产生碳/碳异质结，所述活化剂将氮物质专门沉积在商业微孔碳纤维的表面上。这种类型的碳基双相异质结放大了碳纤维和CO2分子之间的相互作用，以实现异常高的CO2吸收和电阻传感。
CO2 capture is a pressing global environmental issue that drives scientists to develop creative strategies for tackling this challenge. The concept in this contribution is to produce site-specific nitrogen doping in microporous carbon fibers. Following this approach a carbon/carbon heterojunction is created by using a poly(ionic liquid) (PIL) as a "soft" activation agent that deposits nitrogen species exclusively on the surface of commercial microporous carbon fibers. This type of carbon-based biphasic heterojunction amplifies the interaction between carbon fiber and CO2 molecule for unusually high CO2 uptake and resistive sensing.
