摘要：

In this study, the effects of the pretreatment time on the properties of Ni/TiO2 catalysts are examined. The optimum time has been determined to be below 3 h with regard to the catalytic activity. The difference between the CH4 conversion and CO2 conversion drastically increased for a catalyst pretreated for 4 h. The activity tests of the reverse water gas shift reaction (RWGS), temperature-programmed hydrogenation, and elementary reaction of dry reforming over the catalysts showed that the difference between the two conversions was attributed to the high RWGS reaction rate.
