WebDec 16, 2024 · Regarding the crystallite size of Pd, there is no particular trend in the heat treatment although Pd/C k showed smaller crystallite sizes, i.e., 2.2–4.5 nm, than that of Pd/C v, i.e., 4.6–9.4 nm. On the basis of these results, heat treatment provides an enhancement of the total surface area, which is a trend similar to previous studies [ 13 ]. WebAug 24, 2024 · The crystallite size of the Co3O4 catalyst was found to be well correlated with the amounts of surface-adsorbed oxygen species and number of acid sites on the catalyst surface, and consequently, determined several physicochemical properties of the catalyst. Of the catalysts studied here, the Co-AP catalyst exhibits the smallest … dick phillips obituary
