标题： Main-chain poly(ionic liquid)-derived nitrogen-doped micro/mesoporous carbons for CO2 capture and selective aerobic oxidation of alcohols

摘要： 可持续发展以及对能源和功能化学品日益增长的全球需求迫切需要有效的二氧化碳修复方法和高效的无金属催化剂，用于芳香醇的选择性氧化。 在此，一种独特的主链聚(离子液体)（PIL）被用作前驱体，通过同时碳化和活化制备氮掺杂的微孔和介孔碳，其产率高，比表面积超过每克1700平方米，并富含氮掺杂剂。 多孔碳产品在273 K和1 bar条件下具有高达每克6.2毫摩尔的二氧化碳吸附能力，具有出色的可逆性和满意的选择性。 此外，它们作为无金属碳催化剂，在选择性空气氧化苯甲醇制苯甲醛中表现出色，具有高选择性。 相信这项工作不仅提供了一种制备氮掺杂多孔碳的简便方法，还推动了环境和催化领域相关研究的发展。 显示英文摘要

摘要： Sustainable development and the recent fast growing global demands for energy and functional chemicals urgently call for effective methods for CO2 remediation and efficient metal-free catalysts for selective oxidation of aromatic alcohol. Herein, a unique main-chain poly(ionic liquid) (PIL) is employed as the precursor to prepare nitrogen doped micro and mesoporous carbons via simultaneous carbonization and activation, which bear high yield, large specific surface area above 1700 m2 per g and rich nitrogen dopant. The porous carbon products deliver a high CO2 adsorption capacity up to 6.2 mmol per g at 273 K and 1 bar with outstanding reversibility and satisfactory selectivity. Besides, they work excellently as metal free carbocatalysts for the selective aerobic oxidation of benzyl alcohol to benzaldehyde with high selectivity. It is believed that this work not only provides a facile approach to prepare nitrogen-doped porous carbon, but also advances the related research in the fields of environment and catalysis.
