Dry reforming of methane over Ni perovskite type oxides

NO oxidation over Ni–Co perovskite catalysts

“…The specific surface areas (SSA) of LaNi 1Àx Co x O 3 catalysts were relatively low, about 7-11 m 2 /g, which was mainly due to the calcination at the high temperature [18]. It is also notable that the substituted samples had a smaller SSA than LaNiO 3 and the reduction was linear with the substitution, which was in accordance with a previous report [19].…”

“…The reduction temperature of LaCoO 3 was higher than LaNiO 3 in the whole temperature range, so the reduction peaks were gradually shifted to high temperature with the increased content substitution of Ni by Co. This trend was similar with a previous report [18]. The results revealed that LaNiO 3 was not as stable as LaCoO 3 in the reducing environment and that the Co doping was beneficial for improving the stability of LaNiO 3 structure.…”

“…The d-spacing of (1 1 0) calculated from the XRD patterns were listed in Table 1. With the increase of x from 0 to 1, the lattice distance of the (1 1 0) plane decreased from 2.7299 Å to 2.7205 Å, indicating that the Co 3+ ion (0.52 Å) was indeed incorporated into the lattice of the perovskite structure and replaced Ni 3+ ion (0.56 Å) in B site [18]. However, LaNi 0.7 Co 0.3 O 3 had the largest d-spacing, 2.7315 Å.…”

Pure Hydrogen Production in Membrane Reactor with Mixed Reforming Reaction by Utilizing Waste Gas: A Case Study

“…Active metals, including noble metals [42][43][44][45][46] and transition metals [47][48][49][50][51][52][53], could be used to prepare catalyst for mixed reforming. However, the noble metals have a higher coke resistivity in comparison to transition metals, but their main drawbacks are represented by their high prices and the low availability of noble metals [54].…”

Dry Reforming of Methane Over Various Doping Level of Ce on La1-Xcexni0.4Fe0.6o3perovskitenanocatalyst

“…It also reduces CO 2 and CH 4 emissions contributing to the greenhouse effect [1][2] . Synthesis gas can be applied in the Fischer-Tropsch synthesis industry to produce valuable chemicals 3,4 . The low H 2 /CO ratio is preferentially used for further applications such as methanol and liquid fuel synthesis 5,6 .…”
