What if the carbon dioxide building up in our atmosphere could be put to good use as fuel? For years chemists have chased a catalyst that could aid the reaction converting carbon dioxide to methane, a building block for many fuels – and now Duke University scientists have found just such a catalyst in tiny rhodium nanoparticles..

Duke University researchers converted carbon dioxide into methane with the help of rhodium nanoparticles, which harness ultraviolet light’s energy to catalyze car...
