Microbial synthesis of hollow porous Prussian blue@yeast microspheres and their synergistic enhancement of organic pollutant removal performance

Abstract

Prussian blue was in situ grown on S. cerevisiae cells to obtain PB@yeast, which exhibited synergistically enhanced activity in dye wastewater treatment.

Surface-defect engineering of a nickel hexacyanoferrate material for high-performance printed flexible supercapacitors

“…It suggests that the porous structures of NiHCf-etching 8 h may be beneficial for the transport of electrolyte ions. 34 Therefore, this composite structure offers abundant interfaces between the electrode and electrolyte for Na + ion migration, further accelerating the ionic transport speed and enhancing energy densities as shown in the next experiments.…”

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

“…This is consistent with other reports. 32,33 The low photocatalytic efficiency of PB is due to the poor electron conductivity and fast recombination of photoexcited electrons and holes. However, the dark current of TiO 2 and TiO 2 @PB photoanodes is almost zero.…”

“…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. The incorporation of PB into semiconductor photocatalysts might be a desirable strategy to boost their photocatalytic activity.…”

Prussian blue modified CeO2 as a heterogeneous photo-Fenton-like catalyst for degradation of norfloxacin in water

“…Prussian blue (PB), which was recognized as an artificial enzyme of H 2 O 2 , has been employed as Fenton-like catalysts because of the excellent catalytic activity for H 2 O 2 and unique metal-organic frameworks (MOFs) structure (Cheng et al 2019). Based on previous researches, PB and their analogs (PBAs) have been developed as photo-Fenton-like reagents to degrade various organic contaminants (Chen et al 2019). However, few correlative investigations have been focused on the photocatalytic performance and mechanism of CeO 2 supported PB as a Fenton-like and photo-Fenton catalyst.…”
