Sol-gel routes to metal oxide nanoparticles in organic solvents under exclusion of water have become a versatile alternative to aqueous methods. In comparison to the complex aqueous chemistry, nonaqueous processes offer the possibility of better understanding and controlling the reaction pathways on a molecular level, enabling the synthesis of nanomaterials with high crystallinity and well-defined and uniform particle morphologies. The organic components strongly influence the composition, size, shape, and surface properties of the inorganic product, underlining the demand to understand the role of the organic species at all stages of these processes for the development of a rational synthesis strategy for inorganic nanomaterials.
在排除水的情况下，通过溶胶 - 凝胶法在有机溶剂中制备金属氧化物纳米颗粒已成为水相方法的一种通用替代方法。与复杂的水相化学相比，非水过程提供了在分子水平上更好地理解和控制反应途径的可能性，从而能够合成具有高结晶度以及明确且均匀颗粒形态的纳米材料。有机成分强烈影响无机产物的组成、尺寸、形状和表面性质，这突出了在这些过程的所有阶段理解有机物种的作用对于开发无机纳米材料合理合成策略的必要性。
