This study has investigated the propane steam reforming (PSR) performance of M/Ni/YSZ catalysts (M = Ru, Rh, Pd, and Ag) for effective hydrogen production. To improve the catalytic performance, particularly with respect to the duration of the catalyst, YSZ (yttria-stabilized zirconia) is used as a support and noble metals such as Ru, Rh, Pd, and Ag are introduced as promoters. YSZ is used to suppress carbon deposition as it provides lattice oxygen to carbon coke on the catalyst. Noble metals provide synergy, assisting Ni metal in improving dehydrogenation. Preferentially, the PSR performance of 1.0 wt.% M/Ni/YSZ catalysts are measured to find which noble metal is suitable as a promoter. The result confirms that the Rh component is the best promoter for M/Ni/YSZ. This study also demonstrates the appropriate amount of Rh to use, based on the PSR performance over Ni/YSZ and 0.1, 0.5, and 1.0 wt.% Rh/Ni/YSZ for 100 h. The results confirm that Ni/YSZ becomes deactivated at 76 h, but the catalysts with the Rh promoter have much higher durability. Thus, this study concludes that 0.5 wt.% Rh/Ni/YSZ is the best catalyst because it does not have excessive Rh content and also does not show any discernable decrease in the PSR performance. Moreover, the Rh/Ni/YSZ catalysts had a higher resistance to carbon deposition because of the presence of the Rh promoter, which could improve lattice oxygen mobility of the Rh/Ni/YSZ catalyst.

这项研究调查了M / Ni / YSZ催化剂（M = Ru，Rh，Pd和Ag）的丙烷蒸汽重整（PSR）性能，以有效制氢。为了改善催化性能，特别是在催化剂的持续时间方面，使用YSZ（氧化钇稳定的氧化锆）作为载体，并引入诸如Ru，Rh，Pd和Ag的贵金属作为助催化剂。YSZ用于抑制碳沉积，因为它为催化剂上的碳焦炭提供晶格氧。贵金属提供协同作用，协助镍金属改善脱氢作用。优选地，测量1.0重量％的M / Ni / YSZ催化剂的PSR性能以发现哪种贵金属适合作为促进剂。结果证实，Rh组分是M / Ni / YSZ的最佳促进剂。这项研究还证明了使用适量的Rh，基于Ni / YSZ和0.1、0.5和1.0 wt。％Rh / Ni / YSZ在100 h内的PSR性能。结果证实，Ni / YSZ在76 h时失活，但具有Rh助催化剂的催化剂具有更高的耐久性。因此，该研究得出结论，0.5重量％的Rh / Ni / YSZ是最好的催化剂，因为它不具有过量的Rh含量并且也没有表现出PSR性能的任何明显下降。此外，由于存在Rh助催化剂，Rh / Ni / YSZ催化剂具有较高的抗碳沉积性，这可以改善Rh / Ni / YSZ催化剂的晶格氧迁移率。％Rh / Ni / YSZ是最好的催化剂，因为它没有过量的Rh含量，并且在PSR性能上也没有表现出任何明显的下降。此外，由于存在Rh助催化剂，Rh / Ni / YSZ催化剂具有较高的抗碳沉积性，这可以改善Rh / Ni / YSZ催化剂的晶格氧迁移率。％Rh / Ni / YSZ是最好的催化剂，因为它没有过量的Rh含量，并且在PSR性能上也没有表现出任何明显的下降。此外，由于存在Rh助催化剂，Rh / Ni / YSZ催化剂具有较高的抗碳沉积性，这可以改善Rh / Ni / YSZ催化剂的晶格氧迁移率。
