United KingdomA research team led by KU Leuven has developed a new membrane technology using graphene oxide to enhance the purification of industrial solvents like isopropanol. The method allows for faster and more energy-efficient separation of water from isopropanol compared to traditional heating and distillation techniques. This innovation reduces energy consumption and CO₂ emissions in the chemical industry, supporting sustainability goals. The membrane features a dual-function structure with narrow channels for blocking larger molecules and porous regions for selective water transport. Researchers tested the technique on a 90% isopropanol and 10% water mixture, achieving 99.6% pure water output. The findings were published in Nature Communications.
