Abstract

Zeolitic Imidazolate Frameworks-8 (ZIF-8) have emerged as a promising class of porous Metal-Organic Framework materials with a wide range of applications due to their tunable characteristics. This study presents the synthesis of ZIF-8 using the microwave-assisted hydrothermal method in an aqueous solution to investigate the efficiency and characteristics of ZIF-8. The synthesis process involves a 15 min microwave irradiation at 180 °C with a mixture of zinc nitrate solution with 2-methyl imidazole in deionized water with triethylamine. The rapid synthesis yields pure ZIF-8 crystals, as validated by X-ray diffraction, energy-dispersive X-ray spectroscopy, and Fourier-Transform Infrared spectroscopy. The formation of ZIF-8 displays two distinct crystal shapes, with an average size of 0.510 µm, a direct band gap of 4.94 eV as well a BET surface area of 1652.06 m² g⁻¹. The high-quality ZIF-8 produced is ideal for catalysis, gas separation, and other applications, suitable for commercial-scale production.

利用微波辅助水热技术形成沸石咪唑酸框架-8 (ZIF-8)

分子筛咪唑酸酯框架-8 （ZIF-8）由于其可调的特性而成为一类有前途的多孔金属有机框架材料。本研究采用微波辅助水热法在水溶液中合成了ZIF-8，考察了ZIF-8的效率和特性。合成过程包括在去离子水和三乙胺中，用硝酸锌溶液和2-甲基咪唑的混合物在180°C下进行15分钟的微波辐照。通过x射线衍射、能量色散x射线光谱和傅里叶变换红外光谱验证，快速合成得到了纯净的ZIF-8晶体。形成的ZIF-8具有两种不同的晶体形状，平均尺寸为0.510µm，直接带隙为4.94 eV， BET表面积为1652.06 m2 g−1。生产的高品质ZIF-8是催化，气体分离和其他应用的理想选择，适合商业规模生产。
