ZrO(2) nanoparticles were successfully fabricated via a facile hydrothermal process. The diameter and surface area of the as-prepared ZrO(2) nanoparticles were approximately 5-10 nm and 102 m(2)/g, respectively. For the first time, Zr atoms with partial positive charges in a Lewis acid ZrO(2) nanoparticle adsorbent were used for the adsorption of negatively charged phospholipids from Jatropha oil. The capacity for phospholipid adsorption using the ZrO(2) nanoparticles was better than that of commercial ZrO(2) powder due to the larger surface area of the ZrO(2) nanoparticles. Phospholipid removal makes Jatropha oil a potential oil for biofuel applications.
采用简单的水热法成功制备了 ZrO(2)纳米粒子。所制备的 ZrO(2)纳米粒子的直径和比表面积约为 5-10nm 和 102m(2)/g。首次使用带部分正电荷的 Zr 原子作为路易斯酸 ZrO(2)纳米粒子吸附剂，从麻疯树油中吸附带负电荷的磷脂。由于 ZrO(2)纳米粒子具有更大的比表面积，因此其对磷脂的吸附容量优于商业 ZrO(2)粉末。去除磷脂使麻疯树油成为生物燃料应用的潜在油。
