Biomass has emerged as a potential alternative to the dwindling fossil fuel reserves. Catalytic conversion of biomass become main route for transformation into variety commodity chemicals or liquid fuels. Currently, many reviews have effectively documented use homogeneous and heterogeneous catalysts catalytic fuels; however, comparatively less attention been paid magnetic in transformation. Magnetic nanoparticles are well-designed way bridge gap between catalysts. The introduction solid...
