Sol-gel synthesis of cerium dioxide nanoparticles coated with stimuli-responsive components and the application for conversion of d-(−)-fructose into platform molecules

The cerium dioxide nanoparticles that coated with Pluronic P123 and poly(vinyl alcohol), or titanium dioxide are prepared through sol-gel. The coated components such as poly(vinyl alcohol) and titanium dioxide show significant thermo- and pH-responsive properties during catalytic conversion of d-(-)-fructose into platform molecules. High yields of platform molecules could be obtained in water at 20 °C, and synthetic catalysts show satisfactory recycling behaviors.
