Bi- or Sb-promoted Pt catalysts with various Pt/Promoter ratios were supported on activated carbon (AC) by electroless deposition. Samples were characterized by inductively coupled plasma-optical emission spectroscopy (ICP-OES), N2 physisorption, X-r

Oxidative coupling of naphthols is a useful method for the formation of new carbon-carbon bonds in organic synthesis. In the presence of hydrogen peroxide, platinum supported on activated carbon catalyses this reaction. The outcome is influenced by t

Worldwide, more than 85% of all chemical products are manufactured with the help of catalysts. Virtually all transition metals of the periodic table are active as catalysts or catalyst promoters. Catalysts are divided into homogeneous catalysts, whic
