core and the UIO-n shell. The Au@Pd core−shell NPs efficiently controlled the morphology and structure of UIO-67 and enhanced the CO selectivity of the catalyst. Pt NPs increased the CO 2 conversion, and the UIO-n component effectively regulated the reverse water−gas shift reaction.

In this study, a new Zn coordination polymer (Zn-CP), hereafter, 1Zn, was successfully assembled in a solvothermal system, exhibiting one-dimensional extended chains. 1Zn morphologies were controlled by temperature and surfactants. In addition, the catalytic performance of 1Zn microsized CP was investigated. Knoevenagel condensation after 4 h afforded a conversion of 86%, and a conversion greater than 96% was obtained for 4-chlorobenzaldehyde and 4-bromobenzaldehyde because of their electron-withdrawing ligands. In addition, excellent selectivity was achieved for the degradation (64% conversion) of malachite green in aqueous solution. The microcrystal morphology affected the conversion, and a relative catalytic mechanism was proposed. The developed strategy of shape-controlled assembled CPs will certainly enhance new potential applications of micro-CPs.
