P-aminobenzoate-intercalated copper hydroxysalt was prepared by coprecipitation at high pH (∼12). As the pH was reduced to ∼7 on washing with water, the development of partial positive charge on the amine end of the intercalated anion caused repulsion between the layers leading to delamination and colloidal dispersion of monolayers of copper hydroxysalt in water. The dispersed copper hydroxysalt monolayers were used as precursors for the synthesis of copper(I)/(II) oxide nanoparticles at room temperature. While the hydroxysalt layers yielded spindle-shaped CuO particles when left to stand, they formed hollow spherical nanoparticles of Cu(2)O when treated with an alkaline solution of ascorbic acid.
对氨基苯甲酸插层铜羟盐是通过在高 pH（约 12）下共沉淀制备的。在用水洗时将 pH 降低到约 7 时，插层阴离子的胺端部分正电荷的发展导致层间斥力，从而导致铜羟盐的单层分层和胶体分散在水中。分散的铜羟盐单层被用作在室温下合成铜（I）/（II）氧化物纳米粒子的前体。当羟盐层静置时，它们生成了纺锤形的 CuO 颗粒，而当用抗坏血酸的碱性溶液处理时，它们形成了空心的球形 Cu2O 纳米颗粒。
