Carbonaceous supports for Schiff base metal complexes: Strategies for enhanced catalytic efficiency

Recent developments in anchoring metal-Schiff base complexes onto carbonaceous polymeric matrices highlight the growing emphasis on using carbonaceous polymers as versatile support materials. The development of supported metal catalysts has gained significant attention due to their potential to combine the advantages of homogeneous and heterogeneous catalysis. This review explores recent advances in the immobilization of metal-Schiff base complexes onto carbonaceous polymeric supports and its application toward organic transformation reactions. This discussion emphasizes diverse strategies for synthesizing composite materials, particularly the incorporation of metal catalysts into solid supports, such as activated carbon, carbon nanotubes, graphene, and Merrifield resin, which has led to enhanced catalytic performance, stability, and reusability. Additionally, the review addresses challenges related to metal leaching and immobilization techniques, offering insights into the potential of composite carbonaceous polymer matrices for the development of more sustainable and industrially applicable catalytic systems.
