The development of novel nano biocatalytic systems through the immobilization of enzymes on nanoscale materials has attracted much scientific interest and their potential use for applications in various industrial fields has been widely recognized. Among the different types of nanomaterials applied for this purpose, carbon-based materials, such as graphene oxide (GO), the oxidized derivative of graphene, and hierarchical porous carbons (HPC), which possess a multimodal pore size distribution of micro-, meso-, and macropores, have been used for enzyme immobilization. On the other hand, magnetic nanoparticles due to their high surface area, large surface-to-volume ratio and easy separation under external magnetic fields have been broadly utilized as carriers for enzyme immobilization. The functionalization of magnetic nanoparticles with carbonbased nanomaterials has recently attracted great interest as the resulting hybrid nanomaterials combine the properties of both building blocks. In the present study, we investigate the use of hybrid nanomaterials of magnetic iron nanoparticles with GO or HPC as nano supports for the immobilization of cellulolytic enzymes which could be applied to generate glucose feedstock using lignocellulosic biomass. The aim of this work focuses on the investigation of the effect of structural characteristics of hybrid GO and HPC magnetic nanoparticles on the catalytic behavior (activity, thermo stability and operational stability) of cellulolytic enzymes.
