Nitrogen-doped graphene supported ultrasmall manganese oxide nanoparticles for hydrogenation of nitroarenes to aminoarenes.

The accessibility, cost-effectiveness, and stability of catalysts based on 3d transition metals make them highly valuable for both industrial chemical synthesis and organic transformations. Recently, the use of these readily available, and biocompatible metals has garnered considerable interest, particularly in the field of heterogeneous catalysis. However, achieving high catalytic efficiency and mimicking reactivity of noble-metal catalysts often requires additional reagents and toxic solvents.
