Effect Of Silica Coating On The Catalytic Activity Of Maghemite Nanoparticles Impregnated Into Mesoporous Silica Matrix

The search for more efficient catalysts and less polluting, less costly reagents has made heterogeneous catalysis one of the most advantageous processes in this scenario. In this work, recoverable heterogeneous catalysts were prepared by incorporating maghemite nanoparticles (M-NP) into mesoporous silica matrix and further coated with dense or mesoporous layers by the sol-gel process.
