Facile Method for the Preparation of Covalent Triazine Framework coated Monoliths as Catalyst Support
Applications in C1 Catalysis
A quasi chemical vapor deposition method for the manufacture of well-defined covalent triazine framework (CTF) coatings on cordierite monoliths is reported. The resulting supported porous organic polymer is an excellent support for the immobilization of two different homogeneous
