Capture and conversion of CO2 at ambient conditions by a conjugated microporous polymer
Open accessAbstract
Conjugated microporous polymers are a new class of porous materials with an extended π-conjugation in an amorphous organic framework. Owing to the wide-ranging flexibility in the choice and design of components and the available control of pore parameters, these polymers can be tailored for use in various applications, such as gas storage, electronics and catalysis. Here we report a class of cobalt/aluminium-coordinated conjugated microporous polymers that exhibit outstanding CO2 capture and conversion performance at atmospheric pressure and room temperature. These polymers can store CO2 with adsorption capacities comparable to metal-organic frameworks. The cobalt-coordinated conjugated microporous polymers can also simultaneously function as heterogeneous catalysts for the reaction of CO2 and propylene oxide at atmospheric pressure and room temperature, wherein the polymers demonstrate better efficiency than a homogeneous salen-cobalt catalyst. By combining the functions of gas storage and catalysts, this strategy provides a direction for cost-effective CO2 reduction processes. Conjugated microporous polymers are highly flexible materials that may be used for gas storage and catalysis applications. Here, the authors report metal-functionalized conjugated microporous polymers capable of both capturing CO2and functioning as a heterogeneous catalyst in its conversion to propylene carbonate.

Liquid sorbents have high heat and energy demands of the chemical CO2 absorption process.
“Although liquid sorbents are generally more effective at capturing CO2, their associated drawbacks, along with the high heat and energy demands of the chemical CO2 absorption process11–13, highlight the need for the development of more efficient, non-corrosive sorbents with lower regeneration energy requirements.”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
