Traditional distillation (TD) is generally an energy-intensive and inefficient process for separation and purification of liquids in chemical industries. Herein, we developed an interface-enhanced distillation (IED) by employing a well-arranged membrane of reduced graphene oxide (rGO) sheet arrays embedded with silicon dioxide nanofibres (rGO/SiO₂) as the evaporation intermediate layer on the liquid surface. This IED enlarges the evaporation surfaces and weakens the intermolecular forces on the liquid/solid/gas interfaces, realizing the fast and even low temperature fraction collection with less energy consumption. The IED delivers evaporation rates 200%–300% times that of TD, meanwhile having an energy saving of 40%–60% and a time saving of 50%–70% for diverse liquid feeds. In atmospheric IED manner, high boiling point and perishable organics can be collected with high quality at a temperature lower than their boiling points. This IED provides an innovative strategy for highly efficient distillation in chemical industries.

传统的蒸馏（TD）通常是化学工业中液体分离和纯化的能源密集型且效率低下的过程。在这里，我们通过使用排列合理的氧化石墨烯（rGO）薄片阵列嵌有二氧化硅纳米纤维（rGO / SiO ₂）的膜开发了界面增强蒸馏（IED）。）作为液体表面上的蒸发中间层。该IED扩大了蒸发表面，并减弱了在液体/固体/气体界面上的分子间作用力，从而实现了快速而均匀的低温馏分收集，并且能耗更低。IED的蒸发率是TD的200％–300％，同时，对于各种液体进料，其节能40％–60％，时间节省50％–70％。以大气IED方式，可以在低于其沸点的温度下高质量地收集高沸点和易腐烂的有机物。该IED为化学工业中的高效蒸馏提供了创新的策略。
