Abstract

Magnesia aerogel activated by hydrogen spillover at 430 °C or at 200 °C becomes a catalyst for the hydrogenation of ethylene. This catalytic activity, observed already at 50 °C, is further enhanced by a treatment in oxygen at 430 °C.

Abstract

Аэрогель магнезия, активированный обмывкой водородом при 430 или 200°C, становится катализатором гидрирования этилена. Эта каталитическая активность наблюдается уже при 50°C и может быть повышена обработкой в кислороде при 430°C.
