The modification of montmorillonite with metallic species affects directly its crystalline structure, texture, porosity, and surface. The interaction of the metallic molecules with the clay matrix, derived from the modification pathway and the characteristics of the adsorbate, modifies the physicochemical properties of montmorillonite, enabling the creation of materials with varied characteristics to be used both as catalysts and adsorbents. Small amounts of metallic species can confer various structural and physicochemical characteristics on the same montmorillonite matrix, depending on the metal incorporated. The objective of the present study was to create an acid-base catalyst based on montmorillonite K10 (K10 Mnt), modified with Ti, Ce, and Ni, for the catalytic esterification of acetic acid and penta-1-ol. K10-Mnt was modified using particles of Ti and of Ti modified with Ce and Ni. The effect of the inclusion of Ti and modified Ti species on the transformation of the physicochemical properties of the K10 Mnt and their contributions to the catalytic esterification syntheses were investigated. Samples were characterized by scanning electron microscopy coupled to an energy-dispersive X-ray spectroscopy system (SEM-EDS), powder X-ray diffraction (XRD), Fourier-transform infrared spectroscopy (FTIR), physisorption of N₂ at 77 K (BET and BJH), and thermogravimetric analysis (TGA-DTGA). Finally, the original and modified K10 Mnt samples were tested for their catalytic esterification of acetic acid and penta-1-ol in the liquid phase.

金属物质对蒙脱石的改性直接影响其晶体结构、结构、孔隙率和表面。源自改性途径和吸附物特性的金属分子与粘土基质的相互作用改变了蒙脱土的物理化学性质，从而能够产生具有不同特性的材料，可用作催化剂和吸附剂。少量的金属物质可以在相同的蒙脱土基质上赋予各种结构和物理化学特性，具体取决于所掺入的金属。本研究的目的是创建一种基于蒙脱石 K10 (K10 Mnt) 的酸碱催化剂，并用 Ti、Ce 和 Ni 进行改性，用于乙酸和五-1-醇的催化酯化。K10-Mnt使用Ti颗粒和用Ce和Ni改性的Ti颗粒进行改性。研究了 Ti 和改性 Ti 物种对 K10 Mnt 物理化学性质转变的影响及其对催化酯化合成的贡献。通过扫描电子显微镜与能量色散 X 射线光谱系统 (SEM-EDS)、粉末 X 射线衍射 (XRD)、傅里叶变换红外光谱 (FTIR)、N 的物理吸附来表征样品₂ 77 K（BET 和 BJH）和热重分析 (TGA-DTGA)。最后，测试了原始和修改后的 K10 Mnt 样品在液相中对乙酸和 penta-1-ol 的催化酯化反应。
