Synthesis and application of functional Prussian blue nanoparticles for toxic dye degradation

Novel Nanostructured WO3@Prussian Blue Heterojunction Photoanodes for Efficient Photoelectrochemical Water Splitting

“…The band structure of PB was calculated by using density functional theory (DFT), and the band gap was determined to be 1.75 eV . Because of its wide light absorption range and high electrochemical reversibility, PB has been used as a semiconducting photocatalyst for the degradation of organic pollutants. − Liu et al constructed a PBA-TiO 2 Janus nanoreactor with efficient charge separation and transfer, which shows enhanced activities for photocatalytic water spliting . Prussian blue analogue (PBA)/CdS nanocomposites with high performance for photocatalytic hydrogen evolution have been prepared and show high performance for photocatalytic H 2 evolution due to efficient charge migration .…”

Efficient charge migration in TiO2@PB nanorod arrays with core–shell structure for photoelectrochemical water splitting

“…For TiO 2 @PB nanorod arrays, the broad peak at 3245 cm −1 is assigned to the stretching mode of the surfaceabsorbed water and hydroxyl groups. 31 The peaks at 2056, 594 and 494 cm −1 are related to the CN and Fe-C stretching vibrations, confirming the formation of the PB layer. 40 The broad peak centred at 658 cm −1 is attributable to the stretching mode of the Ti-O-Ti bridge.…”

“…29 Moreover, the PB with wide light absorption range and high electrochemical reversibility can promote the photoelectron generation, provide a charge transfer channel and enhance charge storage. 30,31 So PB has been used in the photocatalytic application as a semiconductor photocatalyst. [32][33][34][35] However, the photocatalytic activity of PB is usually lower than that of the semiconductors due to their poor electron conductivity.…”

Construction of a peroxidase nanozyme based on Prussian blue and its application in GSH colorimetric assays

“…[5][6][7][8] PB NPs, in particular, exhibit efficient peroxidase-like activity due to the presence of Fe 3+ /Fe 2+ redox pairs similar to Fe 3 O 4 . 9,10 This peroxidase-like activity can be assessed by their ability to oxidize the colorless peroxidase substrate 3,3 0 ,5,5 0 -tetramethylbenzidine (TMB) to a blue product in the presence of H 2 O 2 . Researchers have harnessed the excellent peroxidase-like activity of PB NPs to construct electrochemical biosensor platforms.…”
