Fabrication of NOTT-220 @I2 via iodine adsorption and immobilization in bismuth organic framework for efficient CO2 photo-reduction
Source abstract
Abstract
In this research, a kind of bismuth-based metal-organic frameworks—NOTT-220 was investigated as an iodine gas adsorbent. NOTT-220 exhibited good adsorption performance, reaching an adsorption capacity of 955 mg·g −1 at 75 ℃. By various characterization methods and DFT calculations, it was demonstrated that the adsorption process of NOTT-220 included both physical and chemical adsorption, the captured iodine is not only in the form of iodine molecules, but is also converted into BiOI, BiI 3 and polyiodide anions. In addition, the adsorbed sample was also used for photocatalytic reduction of CO 2 , showing better catalytic effect than the original sample. Therefore, the results show that NOTT-220 can not only be used as a promising iodine adsorbent, but also the material after iodine adsorption can be further used for photocatalysis to achieve efficient utilization.
