摘要
The increasing atmospheric levels of carbon dioxide (CO2) must be controlled or better reverted to avoid undesirable climate changes. The electrochemical reduction of CO2 into hydrocarbons is the best approach to solve this problem because it will recycle the 'spent' CO2, known as carbon neutral cycle, and will probably be able to remit the energy crises. Nanostructured copper is a novel material known for the efficient and selective reduction of CO2 into hydrocarbons. This review attempts to summarize the recent development of enlarged surface area nanostructured copper for the efficient reduction of CO2 into hydrocarbons using renewable energy resources at low overpotentials. The effects of different reaction conditions (e.g. applied potential, CO2 concentration and electrode surface) on the products and some relationships between these conditions and products are discussed here. Latest achievements in the CO2 electroreduction technology, remaining challenges and perspective research directions for practical applications are also presented. [GRAPHICS] .
