It includes 59 folders and subfolders, 830 experimental data files, with a total size of 76 MB. The data was mainly collected at Guzhenkou Campus of China University of Petroleum (East China), No. Lidao Road, Binhai Street, Huangdao District, Qingdao City, Shandong Province, during the period from January 2023 to December 2025. The security and integrity of the data are guaranteed through regular hard disk backup, password protection, dedicated personnel management, burned storage and other methods. The entire dataset is fully shared, with a public release date of February 2026. To address the thermodynamic equilibrium limitation and CO2 activation challenges in the direct synthesis of DMC from CO2 and methanol, this dataset focuses on the structure-activity relationships of a series of catalysts including CeO2/Beta, Pd/Silicalite-1, Pd-Mo/NaY and others, and reveals the critical roles of oxygen vacancies, metal dispersion and promoter modification on catalytic activity and stability. In the field of gas separation, the dataset covers the preparation, microstructure regulation of zeolite membranes such as LTA, EMT and SOD, as well as their separation performance for gases including CO2, H2, CH4 and others, and clarifies the influence mechanisms of seed crystal size, gel activity and interlayer design on membrane thickness, compactness and selectivity. The dataset contains raw data including catalytic performance tests, structural characterizations (XRD, SEM, TEM, XPS, TPD, in-situ FTIR, etc.) and separation performance evaluations, which provides solid experimental foundations and design guidelines for developing high-efficiency DMC synthesis catalysts and high-performance gas separation membranes.
