The BET surface area,pore size,and pore volume of the supports and the corresponding supported catalysts are listed in Table 1.The SiO2 support exhibits the highest specific sur‐face area of 459.0 m2/g.The specific surface areas ofγ‐Al2O3and CNT are 184.6 and 170.6 m2/g,respectively.After impreg‐nation,the specific surface area and pore volume decrease dramatically due to the coverage and/or blocking of the pore structure[34].The specific surface areas of Co Mn Na/Si O2,Co Mn Na/γ‐Al2O3,and CoMnNa/CNT decrease to 60.7,72.7,and98.4 m2/g,respectively.The pore volumes of SiO2,γ‐Al2O3,and CNT are 0.78,0.52,and 0.57 cm3/g,respectively.However,the pore volumes of the corresponding catalysts decrease to 0.23,0.21,and 0.37 cm3/g after impregnation,respectively.
