Copper foam turns CO2 into useful chemicals

We're going to need to start sequestering CO2 and CH4 if we want to get the runaway greenhouse effect under control.

"The experiments showed that the copper foam converted CO2 into formic acid — a compound often used as a feedstock for microbes that produce biofuels — at a much greater efficiency than planar copper. The reaction also produced small amounts of propylene, a useful hydrocarbon that’s never been reported before in reactions involving copper."
