摘要: Abstract Extremely high specific surface area mesoporous carbon-supported Pd nanoparticle catalysts were prepared with both impregnation and polyol-based sol methods. The silica template used for the synthesis of carbon was removed by NaOH HF etching. Pd/mesoporous synthesized method has as 2250 m 2 /g. In case NaOH-etched impregnated samples, turnover frequency cyclohexene hydrogenation to cyclohexane at 313 K obtained ~ 14 molecules ∙ site − 1  ∙ s . HF-etched samples higher compared samples. However, catalytic activity ~ 3–6 times on which can be attributed presence sodium hydroxylgroups etched solution.
