Chemical–physical synergistic etching enabling deep reconstruction of NiFe Prussian blue analogue for efficient oxygen evolution reaction and Zn–air batteries

Abstract

Prussian blue analogues (PBAs) are promising pre-catalysts for oxygen evolution reaction (OER) and the in-situ reconstructed metal oxyhydroxides during OER are regarded as the real active sites. However, most of...

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

“…3c and S3 †). 32,33 To further elaborate on NiFe-PBA, we also investigated the superficial chemical composition and element valence states of NiFe-PBA. The deconvoluted Ni 2p spectrum indicates that nickel is positive and bivalent existing in NiFe-PBA (Fig.…”

Tailoring the d-band center of porous CoS2 nanospheres via low-electronegative Fe for weakened OH* adsorption and boosted oxygen evolution

“…12 Consequently, it is highly desired to develop highly active and stable non-noble-metal electrocatalysts. 13–20…”

“…12 Consequently, it is highly desired to develop highly active and stable non-noble-metal electrocatalysts. [13][14][15][16][17][18][19][20] Metallic cobalt pyrite (cobalt disulfide, CoS 2 ) catalysts have been recognized as a prospective alternative to noble metal oxides for the OER in alkaline media. 21 However, the reported CoS 2 electrocatalysts are rarely comparable to the high activity of noble metal oxides due to the strong binding between metal atoms and oxygen-containing intermediates (OH*, O* and OOH*).…”

Prussian blue analog‐derived bimetallic phosphide nanoparticles anchored in nitrogen‐doped porous electrospun carbon nanofibers for efficient oxygen evolution reaction

“…[41][42][43][44][45] Recently, bimetallic PBA has been served as an ideal precursor for preparing bimetal phosphides. [46][47][48] For example, Ding et al 49 have prepared bimetallic phosphides derived from Fe-based PBA and explored their electrocatalytic performance. The prepared bimetal phosphides have more active species and faster electron transfer than monometallic phosphides due to the interaction of different metals, thus showing high electrocatalytic activity.…”
