Simultaneous poisoning of sulfur + phosphorus on a platinum-based diesel oxidation catalyst was studied to gain a deeper understanding on the catalyst deactivation. Compared to a single poisoning (sulfur or phosphorus), the simultaneous poisoning had

Au, Pt, and Pt-Au catalysts supported on Al₂O₃ and CeO₂-Al₂O₃ were studied in the oxidation of dichloromethane (DCM, CH₂Cl₂). High DCM oxidation activities and HCl selectivities were seen with all the catalysts. With the addition of Au,
