Unexpected facilitation of the pyrolysis products of potassium ferrocyanide to the electrocatalytic activity of a PdO based palladium iron composite catalyst towards ethanol oxidation reaction (EOR)

Tough, self-healable, antifreezing and redox-mediated gel polymer electrolyte with three-role K3[Fe(CN)]6 for wearable flexible supercapacitors

“…For the PVA-SA-Na 2 SO 4 GPE, this peak shifts to a lower wavenumber, 3429 cm −1 , indicating enhancement of the hydrogen bonding interactions between PVA and SA. After the addition of K 3 [Fe(CN) 6 ], the vibrational frequency for -COO groups on the SA chain was observed to shift to a lower wavenumber because of the coordination between Fe 3+ and -COO [46,50].…”

“…In the C 1s XPS spectra, the largest peaks at 283.88 and 283.78 eV (Fig. S8c) are commonly attributed to sp 2 -hybridized carbon atoms and indicate that carbon was the main constituent of the PVA-SA-K 3 [Fe(CN) 6 ]-Na 2 SO 4 GPE [50]. The O 1s XPS peaks are generally ascribed to C-O, which reveals that hydroxyl groups are the main functional groups of the GPE (Fig.…”

Recent advances in nonmetallic modulation of palladium-based electrocatalysts

“…Considering the importance of the Pd-PdO interface, some design strategies have been demonstrated to boost the catalytic efficiency of PdO/Pd-based nanocatalysts by a combination of constructing Pd-PdO interfaces and incorporating appropriate supports [Table 3]. The complex interactions between Pd/PdO catalysts and their support matrixes may be strongly associated with excellent catalytic performance in several different ways: Firstly, the MO x (M = Ce [156] , Zr [153,157] , Ni [158] , Al [159] , etc.) as the support can dilute the concentration of Pd atoms, thus maximizing the Pd active sites and minimizing the deactivation caused by the metal-sintering processes.…”
