Retraction Note: Capturing carbon dioxide as a polymer from natural gas

Nature Communications 5: Article number: 3961 (2014); Published: 3 June 2014; Updated: 1 November 2016 In this Article, we reported the synthesis of nucleophilic sulfur- and nitrogen-containing porous carbons and their carbon dioxide uptake performance. Specifically, we described a mechanism where the carbon dioxide polymerized in the channels of the porous support.
