The synthesis of vesicular, walnut-kernel-, and tremella-like silica spheres (VSS, WKSS, and TSS) composed of hierarchical or U-shaped mesoporous structures by a pH-based approach was proposed. Spherical bodies with textural mesopores having sizes ranging from 30 to 40 nm were formed as a result of the diameter of the U-shaped silica skeleton.
