摘要:
The present invention inter alia relates to a supported silica bilayer (SiO 2 bilayer) film. In the supported silica bilayer film, the silica bilayer film consists of two atomic layers of corner-sharing SiO 4 tetrahedra, forms in itself a chemically saturated structure and contains pores. The silica bilayer film has a first (1) and a second side (2) and is supported on the first side (1) by a removable polymer film. The invention further relates to a process for producing the supported silica bilayer film, a process for transferring a silica bilayer film, a free-standing silica bilayer film, a stack comprising a plurality of silica bilayer films, a filed-effect transistor having a gate oxide comprising the silica bilayer film or a stack thereof and the use of a silica bilayer film.

The present invention relates to the electrolytic splitting of water using a carbon-supported manganese oxide (MnO X ) composite. Specifically, the present electrolytic splitting of water is carried under neutral electrolyte conditions with a high electrolytic activity, while using an oxygen evolution reaction (OER)-electrode comprising the present carbon-supported MnO X composite. Next, the present invention relates to a process for producing such a carbon-supported MnO X composite as well as to a composite obtainable by the present process for producing the same and to an OER-electrode comprising the carbon-supported MnO X composite obtainable by the present process.
