|A less-expensive way to duplicate the complicated steps of photosynthesis in making fuel|

Argonne National Laboratory researchers have found a new, more efficient, less-expensive way to make fuel — principally, hydrogen — from sunlight and water: linking a synthetic cobalt-containing catalyst to an organic light-sensitive molecule called a chromophore.
Chromophore molecules, such as chlorophyll, are involved in capturing light for photosynthesis.
Currently, the most efficient methods we have for making fuel involve rare and expensive metal catalysts, such as platinum. Although cobalt is significantly less efficient than platinum when it comes to light-induced hydrogen generation, the drastic price difference between the two metals makes cobalt the obvious choice as the foundation for a synthetic catalyst, said Argonne chemist Karen Mulfort.
