Abstract
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. It creates a carbon/carbon heterojunction by using poly(ionic liquid) (PIL) as "soft" activation agent that deposits nitrogen species exclusively on the skin of commercial microporous carbon fibers. Such carbon-based biphasic heterojunction amplifies the interaction between carbon fiber and CO2 molecule for unusually high CO2 uptake and resistive sensing.
