Catalysts play crucial roles in chemical processes. However, many conventional catalysts have suffered from deactivation caused by sulfur-containing molecules which are strongly absorbed onto catalyst surfaces and suppress catalytic reactions. Osaka University researchers have developed a highly active and durable metal-phosphide catalyst for the deoxygenation of sulfoxides. The developed catalyst has a high durability against sulfur-poisoning in contrast with the conventional metal catalysts. Their findings are published in JACS Au.
