Thermo-responsive polymer micelle-based nanoreactors for intelligent polyoxometalate catalysis

• Thermo-responsive polymer micelle-based nanoreactor was fabricated.
• It contained polyoxometalates and poly(N-isopropylacrylamide)-block-poly(L-lysine).
• The wet hydrogen peroxide oxidation of phenol was chosen as a catalysis model.
• The catalytic activity could be controlled.

A series of polymer micelle-based nanoreactor containing polyoxometalates and poly(N-isopropylacrylamide)-block-poly(L-lysine) (PNIPAM-b-PLys-POM) have been successfully constructed. By adjusting the molar ratio of NIPAM/Lys, the temperature-depend catalytic activity of PNIPAM-b-PLys-POM towards catalytic wet hydrogen peroxide oxidation can be controlled. This work highlights the potential of using thermo-responsive micelles as a platform for developing smart catalyst system.
