摘要：

High activity is generated by sudden formation of disordered oxidic platinum over a platinum catalyst supported on alumina (see picture). High temperature and low concentration of carbon monoxide are required to generate high activity. (Graph Presented). © 2008 Wiley-VCH Verlag GmbH & Co. KGaA.
