Coordination polymers for catalysis: Enhancement of catalytic activity through hierarchical structuring

We utilized a novel strategy, hierarchical structuring, to enhance the catalytic activity of coordination polymers. Hierarchical Prussian white crystals with hollow structures and kinked surfaces were synthesized by using a self-aggregation and etching strategy. The hierarchical structure significantly enhanced the catalytic activity of Prussian white in the degradation of methylene blue in comparison to the non-hierarchical Prussian white crystals.
