Synthesis and characterization of single-crystalline PrCO3OH dodecahedral microrods and its thermal conversion to Pr6O11

Boosting the oxygen evolution activity in non-stoichiometric praseodymium ferrite-based perovskites by A site substitution for alkaline electrolyser anodes

“…76 Figure 4a shows two distinct typical peaks at around 933 and 953 eV, which are attributed to Pr 3d 5/2 and Pr 3d 3/2 respectively. 77,78 The difference of ~ 20 eV is consistent with literature values for the spin orbital splitting of the 3d 5/2 and 3d 3/2 praseodymium orbitals. 76,79 Unfortunately, the determination between Pr 3+ and 4+ is challenging due to the complex nature of final state effects in such systems.…”

PrOx catalysts for the combustion of soot generated in diesel engines: effect of CuO and 3DOM structures

“…The diffractograms reveal the stabilization of fluorite-structured cubic Pr 6 O 11 in all catalysts (JCPDS PDF # 42-1121). In turn, the lattice parameters are very similar and are consistent with the value reported in the JCPDS database (0.5467 nm) 26…”

Room‐temperature synthesis and characterization of cross‐like Pr2(C2O4)3·10H2O micro‐particles

“…(Fig. 8b) shows that it almost keeps the morphology of the precursor except for some hole on the Pr 6 O 11 surface, which may be resulted from producing CO 2 and H 2 O gases during the calcination process [16]. The room temperature optical properties of the cross-like Pr 2 (C 2 O 4 ) 3 ·10H 2 O micro-particles were investigated by photoluminescence (Fig.…”

“…2a) suggests that there are no other metal elements on the surface of the sample except for Pr. Figure 2b shows that the binding energy of 935.2 eV and 955.6 eV are Pr 3d 5/2 and Pr 3d 3/2 , respectively [16].…”
