Cobalt dispersed on SrO-ZrO₂ mixed oxide catalysts were prepared by varying the ratios of Sr and Zr. These catalysts were studied for hydrogen production from glycerol steam reforming. The physico-chemical characteristics of the catalysts were investigated by different techniques. Among all the catalysts, 15%Co dispersed on SrO-ZrO₂ with a 1:1 ratio of Sr and Zr catalyst exhibited the best activity with complete transformation of glycerol into gaseous products (H₂, CH₄, CO and CO₂) with 73% hydrogen yield. The catalyst activity varied with the change in Sr-Zr ratio where the redox properties of ZrO₂ improved the water gas shift reaction in glycerol steam reforming. The characterization results reveal that the high activity of the catalyst is mainly due to the presence of a greater number of octahedral sites, small Co particles, Sr-Zr-Co-O solid solution, strong metal support interactions, and basicity. The catalyst is highly stable as it showed consistent performance during time on stream analysis conceded for a period of 50 h.

通过改变Sr和Zr的比例制备分散在SrO-ZrO _{2混合氧化物催化剂上的钴。}研究了这些催化剂用于甘油蒸汽重整制氢。通过不同的技术研究了催化剂的物理化学特性。在所有催化剂中，15%Co分散在SrO-ZrO ₂上，Sr和Zr为1:1的催化剂表现出最好的活性，甘油完全转化为气态产物（H ₂，CH ₄，CO和CO ₂） 73% 的氢气收率。催化剂活性随 Sr-Zr 比的变化而变化，其中 ZrO _{2的氧化还原性质}改进了甘油蒸汽重整中的水煤气变换反应。表征结果表明，催化剂的高活性主要是由于存在更多的八面体位点、小的Co颗粒、Sr-Zr-Co-O固溶体、强金属载体相互作用和碱性。该催化剂高度稳定，因为它在 50 小时的在线分析期间表现出一致的性能。
