Influence of anions on the synthesis of Cu(i)-based coordination polymers along with a series of derived materials for selective photocatalytic properties

Abstract

Coordination polymers (CPs) are a scientifically compelling and evolving class of highly crystalline materials. Owing to their controllable structures and morphologies, CPs can be used as a type of uniformly and periodically atom-distributed precursor and efficient self-sacrificial template to fabricate porous-carbon-related functional materials. In this work, we have used CuCl₂·2H₂O or Cu(NO₃)₂·3H₂O to combine with N,N′-bis(3-pyridinecarboxamide)-1,2-cyclohexane (3-bpah) to construct Cu(I)-based CPs, namely [Cu(3-bpah)Cl]·H₂O (1) and [Cu(3-bpah)(NO₃)] (2), respectively. We have studied the effect of anions on the structure of the compound in detail. Moreover, the two Cu(I)-based CPs were used as precursors for the preparation of derived materials; then foreign elements were doped into the intrinsic CP-based derived materials and their properties were explored. The adsorption capacities and photocatalytic activities were studied in detail.
