Microporous organic hydroxyl-functionalized polybenzotriazole for encouraging CO2 capture and separation

Abstract

We report a mild, hydroxyl functionalized and thermal stable benzotriazole-based aerogel (HO-PBTA), which is inspired by phenolic resin chemistry. Taking advantage of the synergistic adsorption interactions between hydroxy-benzotriazole and CO2, and the phobic effect between benzotriazole and nitrogen (N2), the CO2 uptake capacity of the HO-PBTA reaches an encouraging level (6.41 mmol g−1 at 1.0 bar and 273 K) with high selectivity (CO2/N2 = 76 at 273 K).
