The demand for the azeotropic C2ClF5/C3F8 separation continues to rise owing to the significance of ultrapure fluoride gases for the electronic industry. With a boiling point differential of 1.1 K, separating an azeotropic mixture of C2ClF5/C3F8 through sorption‐based processes under ambient conditions is a preferable alternative to the current energy‐intensive cryogenic separation method. Here, we...
Separations of both C3 alkene/alkane and C4 alkadiene/alkenes are of great commercial significance as propylene and butadiene represent important feedstock chemicals, but the full extraction of them using carbon‐based separating agents has yet to be fully realized. Herein, derived from low‐cost starch precursors, we report a series of ultramicroporous starch‐based carbon materials (SC‐M; M = Na, K,...
