Microporous organic hydroxyl-functionalized polybenzotriazole for encouraging CO(2) capture and separation

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 CO(2), and the phobic effect between benzotriazole and nitr...

Sumario: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 CO(2), and the phobic effect between benzotriazole and nitrogen (N(2)), the CO(2) 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 (CO(2)/N(2) = 76 at 273 K).
