Special pore‐space‐partition CoFePBA hollow framework realizing high‐performance glucose sensing

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 mu A mM(-1) cm(-2) and 267.63 mu A mM(-1) cm(-2) in the concentration range of 5-325 mu M and 325-1025 mu M, respectively, as well as low detection limit of 0.4 mu M (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.
