Boosting nucleophilic attack to realize high current density biomass valorization on a tunable Prussian blue analogue

Abstract

Electrochemical biomass valorization provides a promising approach to generating value-added chemicals. Herein, we have creatively utilized the Prussian blue analogue as a structure template of the anodic catalyst and improved...

From lab to field: Prussian blue frameworks as sustainable cathode materials

“…186 Subsequently, a cathode was developed for sodium-ion storage, consisting of high-quality Na 0.61 Fe[Fe(CN) 6 ] 0.94 ·○ 0.06 , which featured a notable capacity of 170 mA h g −1 . Its charge–discharge profiles are comparable to that observed in LIBs, featuring a potential plateau at approximately 3.0 V. 187 Recently, K 0.22 Fe[Fe(CN) 6 ] 0.805≦*0.195≒4.0 1H 2 O was incorporated as a cathode in potassium-ion batteries. Electrochemically, they operate differently than SIBs and LIBs.…”

An Old Material for a New World: Prussian Blue and Its Analogues as Catalysts for Modern Needs

“…They proposed a reaction mechanism based on the coordination capability of the PBAs toward the functional groups of the reactants (either a carboxylic acid or a triple carbon bond). This work highlights the importance of the proper choice of PBA Methanol oxidation, as promoted by a series of binary PBAs (NiFe, CuFe, CoFe, and FeFe) on nickel foam, was also investigated by Zhang et al [64]. Different performances in terms of Faraday efficiency (FE) were found, depending on the specific PBAs, with particularly good FE performance (94.1% at a current density of 500 mA cm −2 ) being shown by the NiFe PBAs.…”

“…More importantly, according to the authors, PB could also facilitate electron transfer for the oxidative removal of CO (Figure 13), but no experimental proof was shown to support this claim. Methanol oxidation, as promoted by a series of binary PBAs (NiFe, CuFe, CoFe, and FeFe) on nickel foam, was also investigated by Zhang et al [64]. Different performances in terms of Faraday efficiency (FE) were found, depending on the specific PBAs, with particularly good FE performance (94.1% at a current density of 500 mA cm −2 ) being shown by the NiFe PBAs.…”

Multimetallic Prussian Blue Analogue Nanoparticles for Oxygen Evolution Reaction and Efficient Benzyl Alcohol Oxidation

“…11 Similarly, Zhang and coworkers developed NiFe-PBA@NF for methanol oxidation with decent faradaic efficiency (FE). 10 catalytic hydroxymethylfurfural (HMF) oxidation. 9 These findings are intriguing since they demonstrate the potential of bimetallic PBAs for small-molecule electrochemical oxidation, but there is still plenty of scope for further development.…”

“…Recently, bimetallic Prussian blue analogues (PBAs, a type of metal–organic framework) have been investigated for OER and anodic oxidation of diverse organic substrates. − , For example, Han and co-workers reported CoFe-PBA for formate oxidation with high current density . Similarly, Zhang and co-workers developed NiFe-PBA@NF for methanol oxidation with decent faradaic efficiency (FE) . Lie’s group employed CoFe-PBA, NiFe-PBA, and CuFe-PBA material for electrocatalytic hydroxymethylfurfural (HMF) oxidation .…”
