Soft self-templating approach derived covalent triazine framework with exceptional bimodal
porosity as super-adsorbent for all-purpose iodine capture
A soft self-templating synthetic approach has been a super-adsorbent to capture iodine from vapor, aqueous,
adopted to facile prepare a covalent triazine framework and organic phases in the perspectives of safe nuclear
(MeO-CTF600) with extensive bimodal porosity together energy.
