Abstract

A new strategy to synthesize a highly efficient CO 2 capturer by incorporating tetraethylenepentamine (TEPA) into as‐synthesized MCM‐41 (AM) is reported. The amine guest can be distributed in the micelle of the support, forming a web within the mesopore to trap CO 2 molecules and resulting in a high adsorption capacity for CO 2 up to 237 mg g−1. Four samples of the as‐synthesized MCM‐41 with a different amount or type of surfactant are employed as supports to investigate the influence of micelles on the CO 2 adsorption, and the spokelike structure of the micelle in the channel of the support is proven to be essential to the distribution of guest amine. Among these supports, the AM sample is the most competitive due to the advantages of energy and time saving in preparation of the support along with the resulting higher CO 2 adsorption capacity. At the optimal loading of 50 wt % TEPA, the AM‐50 sample exhibits a high adsorption capacity of 183 mg g−1 in the sixth adsorption cycle at 5 % CO 2 concentration.

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.
