Abstract

A simple aqueous coordination self-assembly route has been demonstrated for the synthesis of copper containing ordered mesoporous polymers with mimosa tannin as the precursor and triblock copolymer Pluronic F127 (EO 106 PO 70 EO 106 ) as the template. The introduction of naturally occurring mimosa tannin in lieu of the toxic and costly synthetic precursors makes the aqueous coordination self-assembly strategy a greener and scalable approach for the soft-templating synthesis of ordered mesoporous polymers. Well-dispersed metallic copper nanoparticles were generated in situ without additional chemical reduction process. The synthesized copper containing catalysts with uniform mesopores (8-9 nm), high surface area (532 m 2 /g), and large pore volume (0.65 cm 3 /g) exhibit high catalytic activity for the aerobic oxidation of both activated benzyl alcohol and nonactivated aliphatic and alicyclic alcohols. Under the optimized conditions, the conversions of benzyl alcohol, n-butanol, n-hexanol, n-octanol, cyclohexanol, and cyclooctanol with high selectivity to the corresponding aldehydes and ketones reached 86%, 64%, 56%, 56%, 84%, and 82%, respectively.
