Abstract
Charcoal-supported Pd-Pt catalysts based on Pd-Pt/NOct(4)Cl colloidal alloys have superior activity and selectivity in the oxidation of gluc ose to gluconic acid compared with industrial heterogeneous Pd-Pt cata lysts. According to transmission electron microscopy, X-ray diffractio n/Debye function analysis, X-ray photoelectron spectroscopy, X-ray abs orption near edge structure, and extended X-ray absorption fine struct ure analysis the chemical coreduction of PdCl2 and PtCl2 in the approp riate ratio with NOct(4)BEt(3)H yielded the alloyed Pd-Pt colloids in organic solvents. They are screened by the lipophilic NOct(4)Cl surfac tant layer from coagulation and poisoning. TEM showed colloids of part icle sizes in the range from 1.5 to 3 nm. (C) 1998 Elsevier Science S. A.
