The unique properties of Metal–organic frameworks (MOFs) have made them a highly promising and efficient class of materials for gas adsorption projects. In this piece of research, white-box machine learning algorithms, including gene expression programming (GEP), group method of data handling (GMDH), and genetic programming (GP), are implemented to generate reliable and efficient explicit correlations for estimating CO<sub>2</sub> uptake capacity of MOFs based on the most extensive databank gathered up-to-date containing 6530 data points from 88 different MOFs. The CO<sub>2</sub> uptake capacity is considered a strong function of pressure, temperature, surface area, and pore volume. The results indicated that the GMDH correlation could provide more reliable results by showing total root mean square error (RMSE) and correlation coefficient (R<sup>2</sup>) of 2.77 mmol/g and 0.8496, respectively. Also, the trend analysis reflected that this correlation could precisely detect the physical trend of CO<sub>2</sub> uptake capacity with pressure variations. Moreover, the sensitivity analysis showed the high impact of pressure on the estimated CO<sub>2</sub> uptake capacity values. Based on the sensitivity analysis of the GMDH correlation’s estimations, it can be expected that the CO<sub>2</sub> adsorption capacity of MOFs increases by raising MOFs’ surface area and pore volume and designing the adsorption process at elevated pressures and lower temperatures. The proposed correlation can be simply employed to estimate MOFs’ CO<sub>2</sub> uptake capacity with an acceptable level of confidence using a simple calculator.</p></div>","PeriodicalId":458,"journal":{"name":"Adsorption","volume":"30 8","pages":"1985 - 2003"},"PeriodicalIF":3.0,"publicationDate":"2024-09-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142596027","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Surprisingly, increasing nanoscroll layers, particularly in BN nanoscrolls, does not enhance methane adsorption but rather reduces release capacity. Our molecular simulations reveal a linear relationship between methane release and structural parameters of both carbon and BN nanoscrolls, with carbon nanoscrolls showing higher release independent of structure, while BN nanoscrolls’ release varies with porosity, pore volume, and material density. The stability of this relationship is evident despite limited variability in structural parameters, pointing to elemental composition and molecular force fields as the key determinants of methane release behavior. At 30 MPa, BN nanoscrolls’ volume adsorption marginally meets the DOE target, while carbon nanoscrolls show significant, yet insufficient, progress toward the same goal. Temperature studies indicate that lower temperatures benefit carbon nanoscrolls’ adsorption and release but negatively impact BN nanoscrolls’ release. Our results indicate that while both types of nanoscrolls can meet the DOE’s targets for methane adsorption at low temperatures of 208 K and high pressures of 30 MPa, and have release capacities close to the targets, BN nanoscrolls, unlike carbon nanoscrolls, exhibit higher methane adsorption at low pressures of 0.1 MPa. This leads to more complex release phenomena for BN nanoscrolls. These findings provide critical insights, guiding the design and optimization of nanoscroll materials for enhanced methane adsorption and release in gas storage applications.</p></div>","PeriodicalId":458,"journal":{"name":"Adsorption","volume":"30 8","pages":"1937 - 1946"},"PeriodicalIF":3.0,"publicationDate":"2024-09-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142191530","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
