Controllable synthesis of hollow COFs for boosting photocatalytic hydrogen generation†
Abstract
COF-LZU1 with a cubic hollow structure was fabricated through a hard template approach by using water solvable NaCl as a template. The precisely prepared COF-LZU1 hollow cube displays an enhanced H2 evolution rate (651 μmol h−1 g−1), which is approximately 1.8 times greater than that of pristine COF-LZU1 (361 μmol h−1 g−1).
