The investigation of the influence of hydrothermal synthesis conditions such as synthetic temperature, the amount of solvent, addition of additives including sodium hydroxide, lithium chloride and 2-methylimidazole on the morphology and size of MIL-121 was carried out. The experimental results indicated the significant impact of hydrothermal synthesis conditions on the morphologies and sizes of MIL-121 crystals. The synthesis temperature has little effect on the morphology, which is mainly reflected in the change of the aspect ratio, but the effect on the size is significant under low-temperature conditions. Additives have an important influence on the morphology and size of MIL-121. Our study provides a potential for the improvement of MIL-121 adsorption performance.
研究了水热合成条件如合成温度、溶剂量、添加剂（包括氢氧化钠、氯化锂和2-甲基咪唑）的添加对MIL-121的形貌和尺寸的影响。实验结果表明水热合成条件对MIL-121晶体的形貌和尺寸有显著影响。合成温度对形貌影响较小，主要体现在长径比的变化上，但在低温条件下对尺寸影响显著。添加剂对MIL-121的形貌和尺寸有重要影响。我们的研究为改善MIL-121的吸附性能提供了一种可能。
