Three-dimensional hierarchical Prussian blue composed of ultrathin nanosheets: enhanced hetero-catalytic and adsorption properties

Three-dimensional hierarchical Prussian blue composed of ultrathin nanosheets was successfully synthesized by employing a self-aggregation and oriented attachment strategy. The unique structure highly increases the exposure of micropores and metal sites of Prussian blue to guests, thus significantly enhancing its hetero-catalysis and adsorption properties compared to cubic and commercial counterparts.
