Abstract
⺠Pd/SiO2 catalysts were studied in H2O2 direct synthesis under mild and nonexplosive conditions. ⺠The optimum Pd content is 1.5 wt.% and calcination is mandatory to preserve catalytic performance. ⺠Pd/SiO2 gives the highest selectivity and productivity under the adopted experimental conditions (Pd/SiO2>Pd/ZrO2/SO4=>Pd/ZrO2>Pd/CeO2/SO4=>Pd/CeO2). ⺠Less energetic Pd sites, where O2 chemisorbs without dissociation, are necessary to produce H2O2.
