“…For comparison, ZSM-5(25)-supported other bimetals (Zn−Cu, Zn−Pd, Co− Pd, Zn−In, and Pd−Ce) catalysts were also prepared using the same method. Besides, ZSM-5 with SiO 2 /Al 2 O 3 molar ratios of 21, 25, 38, and 50 supported Zn−Ce catalysts were also synthesized and denoted as Zn−Ce/ZSM-5 (21), Zn−Ce/ ZSM-5 (25), Zn−Ce/ZSM-5 (38), and Zn−Ce/ZSM-5 (50), respectively. It should be pointed out that the SiO 2 /Al 2 O 3 ratio of ZSM was 25 in this study, if it was not illustrated.…”
