Approximately 80% of today’s world’s primary energy consumption comes from fossil fuels, and the resulting release of carbon dioxide (CO₂) contributes to long-term climate change. There is the potential to create a clean, sustainable fuel cycle if CO₂ can be converted back into fuel, such as gasoline. However there is currently no economically viable way to accomplish this due to the inefficiency of chemical processes to make it happen.
To address this, Tim Mueller and Chao Wang explored how to develop copper alloy nanoparticle catalysts that could facilitate the process of converting CO₂ into fuel. This research could lead to a carbon-neutral future in which clean energy sources such as wind and solar power are used to generate electricity, which in turn is used to convert CO₂ into high energy density fuels that are more efficient and useful.
