Gold nanoparticles give an edge in recycling CO2
October 24, 2013
It's a 21st-century alchemist's dream: Turning the Earth's superabundance of carbon dioxide (CO2)--a greenhouse gas--into fuel or useful industrial chemicals. Researchers at Brown University have shown gold nanoparticles can be tuned to selectively reduce CO2 into CO, an active carbon molecule that can be used to make alternative fuels and commodity chemicals. The key is maximizing the particles' long edges, which are the active sites for the reaction.
The National Science Foundation (NSF) is an independent federal agency that supports fundamental research and education across all fields of science and engineering. In fiscal year (FY) 2015, its budget is $7.3 billion. NSF funds reach all 50 states through grants to nearly 2,000 colleges, universities and other institutions. Each year, NSF receives about 48,000 competitive proposals for funding, and makes about 11,000 new funding awards. NSF also awards about $626 million in professional and service contracts yearly.
