Vom Klimakiller zum Rohstoff

Abstract:
Grundsätzlich besteht bei dem Vorhaben, Kohlendioxid chemisch zu verwandeln, eine große Schwierigkeit: Das Molekül ist äußerst energiearm und damit recht reaktionsträge. Daher muss man ihm auf die Sprünge helfen, beispielsweise mit zugeführter Energie oder durch entsprechende Katalysatoren. Kürzlich berichteten Forscher vom Institute of Bioengineering and Nanotechnology in Singapur über eine neuartige Methanolsynthese, die unter milden Bedingungen recht effizient abläuft ("Angewandte Chemie", Bd. 121, S. 6770).

Als Katalysator verwendeten die Wissenschaftler ein sogenanntes heterozyklisches Carben. Dieses Molekül besitzt ein freies Elektronenpaar, welches an das Kohlendioxid-Molekül andockt und es auf diese Weise aktiviert. Als Wasserstoffquelle dient Hydrosilan. Da diese Substanz vergleichsweise teuer ist, suchen die Forscher nach günstigerem Ersatz.
