We report a mesoporous hafnium oxide (MHO) ceramic synthesized via a sol–gel process that has exhibited 99.9% removal capacity of crude oil from an oil-in-water emulsion at a concentration of 3 mg mL⁻¹. The as-prepared MHO ceramic was regenerated after crude oil sequestration via calcination at 800 °C under ambient conditions. The scalability of the synthetic method and thermal stability of the MHO ceramic material makes it a promising, underexplored, and reusable adsorbent for efficient oil spill clean-up.

介孔氧化ha陶瓷从原油-水乳液中吸附原油

我们报道了一种通过溶胶-凝胶工艺合成的介孔氧化ha（MHO）陶瓷，该陶瓷在3 mg mL ^-1的浓度下从水包油乳液中去除了99.9％的原油。所制备的陶瓷MHO被原油封存后再生通过煅烧在环境条件下800℃。合成方法的可扩展性和MHO陶瓷材料的热稳定性使其成为一种有希望的，开发不足且可重复使用的吸附剂，可用于有效的溢油清理。
