“…In order to improve the stability, partial substitution for Ni site was examined. It was reported that not only stability but also conductivity and oxygen permeation rate could be improved by the substitution (13)(14)(15)(16)(17)(18)(19)(20)(21)(22)(23)(24)(25). Miyoshi and coworkers (18) O.…”

Structural phase diagram of Nd 2 Ni 1-x Cu x O 4+δ , a promising new cathode material for solid oxide fuel cells, was established. The single phase with K 2 NiF 4 -type crystal structure was obtained for the specimens with x≤0.3. Single phase with crystal structure of T'-phase was obtained for Nd 2 CuO 4 . For the specimens with x between 0.4 and 0.9, phase separation into K 2 NiF 4 structure and T'-phase structure due to miscibility gap was observed. In the miscibility gap, Cu content, x, of both K 2 NiF 4 phase and T'-phase was constant and the compositional ratio of T'-phase linearly increased with increasing x. High temperature X-ray diffraction measurements revealed that the miscibility gap remained up to 1000°C for the specimens with x between 0.4 and 0.9.

“…The majority of these studies focused on the dry reforming of methane [3,[35][36][37][38][39][40][41][42][43] and to a lesser extent on the reformation of other feedstocks such as acetic acid [44,45], biomass tar [46], bio-oil [47], diesel [48][49][50], ethane [51], ethanol [52][53][54], glycerol [55,56], phenol [57], and toluene [58,59]. The propane reforming over perovskitederived catalysts has rarely been reported in the literature [60][61][62]. For example, Lim et al [60] investigated the autothermal reforming of propane over Ce-modified Ni/LaAlO 3 catalysts and reported the increased thermal stability and low carbon deposition over the Ce-doped sample.…”

Yeyongchaiwat et al [62] studied the oxidative reforming of C 3 H 8 over Pr 2 Ni 0.75 Cu 0.25 Ga 0.05 O 4 perovskite whereas Sudhakaran et al [61] investigated the dry reforming of propane over the SrNiO 3 catalyst. The observed enhancement of CO selectivity and minimal carbon formation was attributed to the strong basicity of the perovskite [61].…”

Propane Steam Reforming over Catalysts Derived from Noble Metal (Ru, Rh)-Substituted LaNiO3 and La0.8Sr0.2NiO3 Perovskite Precursors

et al. 2021

The propane steam reforming (PSR) reaction was investigated over catalysts derived from LaNiO3 (LN), La0.8Sr0.2NiO3 (LSN), and noble metal-substituted LNMx and LSNMx (M = Ru, Rh; x = 0.01, 0.1) perovskites. The incorporation of foreign cations in the A and/or B sites of the perovskite structure resulted in an increase in the specific surface area, a shift of XRD lines toward lower diffraction angles, and a decrease of the mean primary crystallite size of the parent material. Exposure of the as-prepared samples to reaction conditions resulted in the in situ development of new phases including metallic Ni and La2O2CO3, which participate actively in the PSR reaction. The LN-derived catalyst exhibited higher activity compared to LSN, and its performance for the title reaction did not change appreciably following partial substitution of Ru for Ni. In contrast, incorporation of Ru and, especially, Rh in the LSN perovskite matrix resulted in the development of catalysts with significantly enhanced catalytic performance, which improved by increasing the noble metal content. The best results were obtained for the LSNRh0.1-derived sample, which exhibited excellent long-term stability for 40 hours on stream as well as high propane conversion (XC3H8 = 92%) and H2 selectivity (SH2 = 97%) at 600 °C.

“…In order to improve cathode property and stability of Ln 2 NiO 4+δ (Ln: La, Pr, Nd) with K 2 NiF 4 -type structure (T-phase), partial substitution of Cu for Ni site was examined (1)(2)(3)(4)(5)(6)(7)(8)(9)(10)(11)(12). It was reported that not only stability but also conductivity and oxygen permeation rate could be improved by the substitution.…”
