Controllable Fabrication of Coordination Polymer Particles (CPPs): A Bridge between Versatile Organic Building Blocks and Porous Copper-Based Inorganic Materials
Hierarchically micro-/nanostructured coordination polymer
[CuÂ(2,5-PDC)ÂH<sub>2</sub>O]<sub><i>n</i></sub> architectures
with tunable
morphologies have been successfully prepared by rationally adjusting
the preparation parameters, such as the reactant concentration, solvent,
surfactant, and reaction temperature. Using simple calcinations of
chosen shaped [CuÂ(2,5-PDC)ÂH<sub>2</sub>O]<sub><i>n</i></sub> architectures, we can obtain several porous copper-based inorganic
motifs, which show potential applications for the antibacterial field
and lithium ion batteries. Therein, CuO-1 can kill the Gram-positive
bacteria <i>Bacillus subtilis and Staphylococcus aureus</i> better than other materials. The value for initial discharge capacity
of CuO-3 (1160 mAh g<sup>–1</sup>) is higher than the theoretical
capacity (674 mAh g<sup>–1</sup>) and most copper oxide materials.
Besides, Cu/C composites also show intense application in the antibacterial
and Li-ions uptake-release field, which will provide a widely used
method to prepare the nanosystem of carbon-coating or carbon-compositing
materials by simple calcinations of shaped precursor coordination
polymer particles used under the proper temperature
