Summary: A series of TEMPO@PCN-222 composite photocatalysts were developed by coordinating different amount of 4-carboxy-TEMPO with the secondary building units of PCN-222. Visible-light irradiation enables the transfer of photogenerated holes in the highest occupied molecular orbital of PCN-222 to TEMPO, significantly increasing the photosynthesis of bioactive (iso)quinolones. With an outstanding catalytic stability and substrate tolerance, TEMPO@PCN-222 exhibits a yield of 86.7% for 1-methyl-2-quinolinone, over four times higher than PCN-222 (21.4%). This study provides a new route for constructing composite photocatalysts from abundant starting materials for efficient photosynthesis of high value-added chemicals.

Summary: The potential of TEMPO-mediated oxidation to produce CNFs is hindered by the use of expensive and environmentally harmful catalysts. This research identifies key parameters for reusing the TMO medium and their impact on CNF quality. Contrary to previous hypothesis, concentration of salts is not a key parameter; instead, high pulp consistency during oxidation leads to better CNF quality. Reusing the reaction medium up to six times significantly reduces catalyst dose, reaction time, and effluent, resulting in a threefold increase in CNF production.
