The burning of fossil fuels produces carbon dioxide emissions, increased levels of which cause serious environmental problems. Therefore, the design and use of new materials as media for capturing carbon dioxide and other gases, such as hydrogen and methane, has attracted significant research attention. In this work, three metal complexes containing a fusidate moiety were synthesized and tested as storage media for gases. By reacting sodium fusidate and metal chlorides in boiling ethanol, the corresponding metal complexes were obtained with 69–76% yields. The fusidate moiety acts as a bidentate ligand with variable geometry (distortion octahedral, square planner, or tetrahedral) depending on the metal (manganese, copper, or zinc, respectively) it is associated with. The elemental composition of the metal complexes was confirmed via energy dispersive X-ray spectroscopy and their surface morphology was inspected via field emission scanning electron microscopy. The Brunauer-Emmett-Teller surface area of the metal complexes varied from 31.2 to 46.9 m 2 /g, with pore volume and diameters of 0.035–0.049 cm 3 /g and 3.02–3.18 nm, respectively. The gas uptake at 323 K for carbon dioxide, hydrogen, and methane depended on the metal, gas, surface pore volume, and pore diameter. Reasonable carbon dioxide uptake (6.3–7.2wt%) was achieved with fusidate metal complexes at high temperature and pressure, whereas hydrogen and methane slowly permeated throughout the complexes.

作为储气介质的含夫西酸盐部分的新型多孔金属配合物的合成和应用

化石燃料的燃烧会产生二氧化碳排放，二氧化碳排放量的增加会导致严重的环境问题。因此，设计和使用新材料作为捕获二氧化碳和其他气体（如氢气和甲烷）的介质引起了人们的广泛关注。在这项工作中，合成并测试了三种含有梭链孢酸部分的金属配合物作为气体的存储介质。通过将夫西酸钠和金属氯化物在沸腾的乙醇中反应，以 69-76% 的产率获得相应的金属配合物。根据与之相关的金属（分别为锰、铜或锌），梭链孢部分充当具有可变几何形状（扭曲八面体、方形平面或四面体）的双齿配体。通过能量色散 X 射线光谱确认金属配合物的元素组成，并通过场发射扫描电子显微镜检查其表面形态。金属配合物的Brunauer-Emmett-Teller 表面积从31.2 到46.9 m 2 /g 不等，孔体积和孔径分别为0.035-0.049 cm 3 /g 和3.02-3.18 nm。二氧化碳、氢气和甲烷在 323 K 时的气体吸收量取决于金属、气体、表面孔体积和孔径。在高温和高压下使用夫西地酸金属配合物实现了合理的二氧化碳吸收（6.3-7.2wt%），而氢气和甲烷缓慢渗透到整个配合物中。金属配合物的Brunauer-Emmett-Teller 表面积从31.2 到46.9 m 2 /g 不等，孔体积和孔径分别为0.035-0.049 cm 3 /g 和3.02-3.18 nm。二氧化碳、氢气和甲烷在 323 K 时的气体吸收量取决于金属、气体、表面孔体积和孔径。在高温和高压下使用夫西地酸金属配合物实现了合理的二氧化碳吸收（6.3-7.2wt%），而氢气和甲烷缓慢渗透到整个配合物中。金属配合物的Brunauer-Emmett-Teller 表面积从31.2 到46.9 m 2 /g 不等，孔体积和孔径分别为0.035-0.049 cm 3 /g 和3.02-3.18 nm。二氧化碳、氢气和甲烷在 323 K 时的气体吸收量取决于金属、气体、表面孔体积和孔径。在高温和高压下使用夫西地酸金属配合物实现了合理的二氧化碳吸收（6.3-7.2wt%），而氢气和甲烷缓慢渗透到整个配合物中。
