Improving catalytic activity by synergic effect between base and acid pairs in hierarchically Porous Chitosan@Titania nanoreactors

Abstract

(Figure Presented) The beneficial effect of the afunctional character of the chitosan@titania hybrid In heterogeneous catalysis was elucidated: considering a prototypical Henry condensation, Michael addition, and Jasminaldehyde synthesis, the cohabitation of a basic site (NH2) and an acidic site (Ti) in the same reactor provided clear activity and selectivity enhancements, with respect to the monofunctional acidic titania and basic chitosan counterparts. © 2010 American Chemical Society.
