Poly(ionic liquid)-Derived Carbon with Site-Specific N-Doping and Biphasic Heterojunction for Enhanced CO2 Capture and Sensing [PDF]

Angewandte Chemie International Edition, Volume56, Issue26, June 19, 2017,Pages 7557-7563, 2018
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 ...
