The effect of non-ionic copolymer surfactant Pularonic P123 on textural and structural properties of ZIF-8 at different conditions was investigated. The varied synthesis parameters were the molar ratio of surfactant to precursors, synthesis temperature and required synthesis time of ZIF-8. Different molar ratios of Pluronic P123 to a mixture of 2-methyl imidazole (MeIM) and Zinc nitrate hexahydrate, (Pluronic P123/Zn(NO₃)₂. 6 H₂O + MeIM): 4/1, 2/1, 1/1, 1/2, 1/4) were used as precursors for the synthesis of Zeolitic Imidazolate Framework-8 (ZIF-8). The synthesis of the smallest ZIF-8 sample particles was also performed at temperatures of 30, 40, 50 and 60 ^°C. ZIF-8 particles were also synthesized with different duration of nucleation and growth (30, 60, 120, 240 and 480 min). XRD, SEM, gravimetric analysis of crystallinity degree, zeta potential and Laser particle size analysis, were applied to characterize the synthesized samples. The effects of different parameters and synthesis environments on the gas sorption capacity of ZIF-8 were also investigated using N₂ adsorption-desorption isotherms, BET and DFT analysis. The overall results showed that the increases of surfactant concentration, time and temperature had an increasing effect on the pore size, pore volume and BET surface area of ZIF-8. Compared with the pure ZIF-8 sample, the increased mesoporosity of modified samples did not lead to superior sorption capacity of ZIF-8 except for two samples synthesized at the highest temperatures due to the heightened hydrophobicity of PPO and PEO groups of Pluronic P123 in those samples. The modification using Pluronic P123 has successfully enlarged the pores of ZIF-8 up to 2.7 nm. This enlargement in pore size together with an increase in the pore volume of ZIF-8 samples were identified as the main reason for the increase in CO₂/CH₄ and CO₂/N₂ solubility selectivity of the modified samples in adsorption experiments conducted at 298 K.

研究了非离子共聚物表面活性剂Pularonic P123在不同条件下对ZIF-8织构和结构性能的影响。不同的合成参数是表面活性剂与前体的摩尔比，合成温度和所需的ZIF-8合成时间。的Pluronic P123的不同的摩尔比到2-甲基咪唑（MEIM）和硝酸锌六水合物的混合物中，活性剂（Pluronic P123 /锌（NO ₃）₂ 6 H。₂ O + MEIM）：4/1，2/1，1 / 1、1 / 2、1 / 4）用作合成沸石咪唑酸酯骨架8（ZIF-8）的前体。最小的ZIF-8样品颗粒的合成也在30、40、50和60  ^°还合成了具有不同成核和生长持续时间（30、60、120、240和480分钟）的C. ZIF-8颗粒。用XRD，SEM，结晶度的重量分析，ζ电位和激光粒度分析对合成样品进行表征。还使用N ₂研究了不同参数和合成环境对ZIF-8气体吸附能力的影响。吸附-解吸等温线，BET和DFT分析。总体结果表明，表面活性剂浓度，时间和温度的增加对ZIF-8的孔径，孔体积和BET表面积具有增加的影响。与纯ZIF-8样品相比，改性样品的中孔性增加并未导致ZIF-8的优异吸附能力，除了两个在最高温度下合成的样品外，这是因为Pluronic P123中PPO和PEO基团的疏水性增强样品。使用Pluronic P123进行的修饰已成功将ZIF-8的孔扩大到2.7 nm。孔径的增加以及ZIF-8样品孔径的增加被认为是CO ₂ / CH ₄和CO增加的主要原因。改性样品在298 K吸附实验中的₂ / N ₂溶解度选择性。
