摘要
Abstract In this work for the first time pore‐space‐partition (PSP)‐CoFePBA hollow framework is elaborately designed and successfully obtained via self‐template internal dissolution strategy. As is demonstrated by our previous report, Prussian blue analogue (PBA) with hollow morphology is very beneficial to improve sensing performance. As expected, the PSP‐CoFePBA hollow framework in this work exhibits far superior glucose sensing performance compared with classic CoFePBA nanoparticles and nanoboxes as well as most of reported PBA‐based glucose sensors. Herein, very high sensitivity of 1184.18 μA mM −1 cm −2 and 267.63 μA mM −1 cm −2 in the concentration range of 5–325 μM and 325–1025 μM, respectively, as well as low detection limit of 0.4 μM (S/N=3) and high stability can be observed. In a word, this work proposes and develops a simple and general synthetic strategy for constructing PBA‐based hollow material, that will be very helpful in this field.
