“…In addition, Yb 2 O 3 was used as an additive to improve the performance of Ni, where conversion of methane to CO and H 2 , otherwise known as syngas, was performed at lower temperatures of 300-700°C [16]. Yb 2 O 3 was also used for the conversion of alcohols and dehydrogenation of tetralin and it was found that Yb 2 O 3 , in comparison to Dy 2 O 3 , Gd 2 O 3 , and Tu 2 O 3 , had the highest dehydrogenating and dehydrating activity [17].…”
