Modification of p-type Silicon for the Photoelectrochemical Reduction of CO_(2)

摘要

Global warming induced by the increase of greenhouse effect gases in the atmosphere appears as one of the most important and urgent problem for this century. Anthropologic emission of carbon dioxide, mainly due to the intensive use of fossil fuels for energy production since two centuries, is the principal contribution to this effect (1). Several approaches are proposed to reduce the CO_(2) emission, besides the reduction of the global energy consumption and the use of cleaner and renewable energy source. A first approach is to capture and store carbon dioxide in geological structure like depleted oil field for example.
