Background: Core-magnetic composites offer unique possibilities to accommodate adequate amounts of acid-base and redox functional sites and hence to catalyze the biomass conversion reactions in a one-pot way. Moreover, due to the dual functionality the core-magnetic composites provide a bridge between homogeneous and heterogeneous catalysis. Hence, this minireview aims to offer a comprehensive account of remarkable recent applications of core-magnetic composites in the catalytic processes for biomass valorization.

Methods: A critical evaluation of synthetic methodologies utilized for the production of the magnetic nanoparticles, characterization techniques and catalytic applications is provided.

Results: The benefits of their utilization are exemplified by most representative exemples of one-pot transformation of cellulose and up-grading processes. Other recent examples constitute the lignin fragmentation on magnetic iron oxide-based catalysts and the renewable crude glycerol up-grading using core-shell magnetic iron oxide bio-based materials.

Conclusion: The review provides important information upon the distinctive properties of the functionalized core-magnetic composites. Very important also, this review offers useful information affording a large-scale production development, in terms of catalyst and reaction conditions, tailoring selectivity, and potential to regenerate the catalysts.
