One-step preparation of Ag nanoparticle–decorated coordination polymer nanobelts and their application for enzymeless H2O2 detection

In this paper, we report on the one-step preparation of Ag nanoparticle (AgNP)-decorated coordination polymer nanobelts, carried out by direct mixing of an aqueous AgNO3 solution and a N,N-dimethylformamide (DMF) solution of 4,4′-bipyridine (BPD) at room temperature. The construction of an enzymeless H2O2 sensor using such nanocomposites with a detection limit of 0.9 μM is also demonstrated.

► We develop a one-step preparative strategy toward AgNP–CPNBs for the first time.
► Such AgNP–CPNBs exhibit good catalytic activity toward H2O2 reduction.
► This enzymeless H2O2 sensor exhibits a detection limit of 0.9 μM.
