本发明属于材料合成催化技术领域,特别是涉及一种金属卤化物耦合的三嗪基多孔有机骨架、制备方法及其应用。
背景技术
二氧化碳(CO2)是导致全球变暖的主要温室气体之一,其过量排放已对生态环境和社会发展产生了严重的负面影响,如冰山消融、土地干旱、森林火灾、气候反常等。同时,CO2还是汇集高储备量、廉价、无毒和可再生等优点的C1资源,利用CO2为原料,通过研发高性能催化技术将其转化为高附加值化学品,对环境保护与可持续发展具有重要意义。但是鉴于CO2高的热力学稳定性和动力学惰性,已报道的电催化、光催化或热催化转化CO2为不同高附加值化学品仍有局限性。据统计,现阶段工业所消耗的CO2量仅占全球总排放量的0.36%。因此,CO2的高效资源化利用尚有很大的发展空间。
CO2与环氧化物的环加成反应是CO2高效资源化利用的有效策略之一。该环加成过程可展现出高的原子经济性与环境友好性,同时合成的环状碳酸酯具有高偶极矩、高沸点、高闪点、低挥发性、低毒性、良好的溶解性与生物降解性等特点,可被广泛用于润滑剂、萃取剂、医药中间体及精细有机体的制备与合成等领域。但考虑到CO2分子的化学惰性,开发能够高活性、高选择性活化与转化CO2的催化体系至关重要。
基于CO2与环氧化物的环加成机理,工业上常以均相KI或四丁基溴化铵(TBAB)催化为主,但该催化过程需引入高温、高压的苛刻反应条件,且催化剂易溶于反应产物,导致催化体系分离与产物提纯比较困难。
近年来,从环加成反应对催化剂结构的要求出发,已开发了许多具有不同功能位点的高效催化体系,如:含有Co/Al/Fe(III)的salen配合物、类沸石框架、氢键供体修饰的离子液体、多金属氧酸盐、碳氮材料、共价有机框架(COFs)和金属有机框架(MOFs)等。上述开发的催化体系虽然可表现出高效的催化性能,但仍不可避免的存有催化剂的单体价格昂贵、合成工艺繁琐、结构不稳定、催化条件苛刻及分离与再利用困难等弊端,这限制了其大规模应用。

实施例16
为进一步说明本发明的优势,将本发明所提出的其中金属卤化物耦合的三嗪基多孔有机骨架催化剂(Zn@PIT-POF-I)与文献报道的其它类型催化剂进行对比。具体依照文献中的条件,本实施例仅做了温度、压力和时间上的摘录,对比得出结论:本发明可实现温和、无溶剂和助催化剂条件下高选择性合成环状碳酸酯,且催化条件及活性均得到明显改善。实验结果如表3所示:
表3
本发明还分别测定了实施例1、实施例2和实施例3中制备的Zn@PIT-POF-Cl、Zn@PIT-POF-Br和Zn@PIT-POF-I的N2吸/脱附曲线和孔径分布曲线,如图4所示:
其中,图A为Zn@PIT-POF-Cl、Zn@PIT-POF-Br和Zn@PIT-POF-I的N2吸/脱附曲线,由图A可知,该类材料的BET表面积为554-612m2/g。所有材料在0<P/P0<0.05的低相对压力区域都表现出急剧的N2吸收/解吸现象,这表明材料中存在大量微孔,随着相对压力的增加,所有曲线均呈现典型的IV型等温线,并伴有明显的H1型回滞环,这表明材料还同时存在丰富的中孔。

本发明还测定了Zn@PIT-POF-I的扫描电镜(SEM)及元素分布谱图,如图5所示,Zn@PIT-POF-I材料的形貌为具有相对均匀颗粒尺寸的球形聚集体,其结构内存在并均匀分布C、N及后修饰的Zn、I元素。
本发明还测定了实施例1、实施例2和实施例3中制备的Zn@PIT-POF-Cl、Zn@PIT-POF-Br和Zn@PIT-POF-I的CO2吸附曲线,如图6所示,低温、高压条件有利于CO2的吸附。其中,Zn@PIT-POF-I材料可在273K条件下表现出最高2357μmol/g的CO2吸附量,这表明高的比表面积、层次化的孔隙结构和窄的孔径能够显著提高对CO2的吸附性能。此外在相同条件下,该类材料的吸附性能也优于大多数已报道的多孔有机聚合物。
