具有有趣的结构图案和独特性质的金属有机框架（MOF）是二氧化碳（CO2）储存的潜在候选者。尽管具有单一功能结构和微孔的结构被证明可以在低温下以高容量捕获二氧化碳，但它们微弱的相互作用仍然限制了在室温下的实际应用。在此，我们报告了铜（II）苯-1,3,5-三羧酸盐（Cu-BTC）掺杂MOF中分层孔的原位生长观察，该MOF具有高吸附性并增强了CO2结合能力。因此，了解这种一直引起争议的二氧化碳捕获机制对于进一步发展高级研究至关重要。掺杂的MOFs表现出1180 m(2) g(-1)的高比表面积，并表现出良好的CO2储存能力，这主要是由于酸和胺功能化的CNT的存在以及大量狭窄的微孔的存在。
Metal organic-frameworks (MOFs) with intriguing structural motifs and unique properties are potential candidates for carbon dioxide (CO2) storage. Although structures with the single functional constructions and micropores were demonstrated to capture CO2 with high capacities at low temperature, their feeble interactions still limit practical applications at room temperature. Herein, we report in situ growth observation of hierarchical pores in copper(II) benzene-1,3,5-tricarboxylate (Cu-BTC) doped MOFs which gives high adsorption and enhances the CO2 binding ability. Thus, understanding this CO2-capturing mechanism, which has been causing controversy, is crucial for further development toward advanced study. The doped MOFs exhibit high specific surface areas of 1180 m(2) g(-1) and show good capacity to store CO2, which is mainly due to the presence of acid and amine functionalized CNTs and a large amount of narrow micropores (
