Evidence of Pressure Enhanced CO<sub>2</sub> Storage in ZIF-8 Probed by FTIR Spectroscopy
Bibliographic record
Abstract
Due to the large porosity and unique framework stability, ZIF-8, a representative zeolitic imidazolate based member of metal-organic framework (MOF) family exhibited excellent adsorption capacities for a wide range of gases, including greenhouse gases. Using in situ FTIR spectroscopy, ZIF-8 framework was investigated when loaded with CO2 in a diamond anvil cell at high pressures far beyond the conventional gas adsorption pressure. The IR profile of CO2 as well as the ZIF-8 shows direct evidence of the interactions between CO2 and ZIF-8, indicating enhanced storage of CO2 in the framework. In addition, the storage behavior was found to be strongly pressure dependent, and the interaction mechanism was explored. These findings demonstrated great potential in the greenhouse gases storage applications using MOF based materials.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
