2026-07-20 Related data of the article "Preparation and CO2/N2 Separation Performance of Multi porous Ni-MOF-74/Diatomaceous Earth Composite Materials" doi:10.57760/sciencedb.jim.00082 en This dataset contains the raw data and chart files that support the main conclusions of the paper "Preparation of Multi porous Ni-MOF-74/Diatomaceous Earth Composite Materials and Study on CO2/N2 Separation Performance". The data content corresponds to Figure 1-8 and supplementary charts in the paper, covering the preparation, structural characterization, CO2/N2 adsorption and separation performance, cycling stability, mass transfer kinetics, and adsorption mechanism analysis of Ni-MOF-74/DE composite materials. Among them, Figure 1 is a schematic diagram of the preparation process of Ni-MOF-74/DE composite material; Figure 2 contains XRD, FTIR, TG, and N2 adsorption desorption isotherm data for DE, Ni-MOF-74, and Ni-MOF-74/DE; Figure 3 shows the SEM morphology and EDS elemental distribution data of the sample; Figure 4 shows the XPS full spectrum and high-resolution spectra of C1s, O1s, and Ni2p of the sample. Figure 5 shows CO2 adsorption data under different metal centers and preparation conditions, as well as CO2/N2 static adsorption desorption isotherms and dynamic breakthrough curves; Figure 6 includes CO2/N2 adsorption isotherm fitting, IAST selectivity, literature performance comparison, and CO2 equivalent adsorption heat data; Figure 7 contains data on CO2 adsorption desorption cycle stability, adsorption kinetics fitting, CO2/N2 competitive adsorption, and ZLC mass transfer analysis; Figure 8 contains in-situ DRIFTS spectral data at different adsorption times and temperatures. This dataset can be used to reproduce the main charts of the paper, verify the structural characteristics, CO2 capture performance, CO2/N2 separation ability, cycling stability, and adsorption mechanism of Ni-MOF-74/DE composite adsorbent, and provide data support for subsequent research on related multi-stage porous MOF based adsorbent materials.  CO2 capture; Ni-MOF-74; diatomite; reflux condensation method; hierarchical pore structure Qian Chengguang Wen Yi Xu Yihan Li Xiaohan yuan fang Li Chunquan Sun Zhiming RESTRICTED dataset Science Data Bank
