"...Supramolecular complexes created by Karen Brewer's group at Virginia Tech convert light energy (solar energy) into a fuel that can be transported, stored, and dispensed, such as hydrogen gas.
The process has been called artificial photosynthesis, says Brewer, associate professor of chemistry. "Light energy is converted to chemical energy. Solar light is of sufficient energy to split water into hydrogen and oxygen gas, but this does not happen on its own; we need a catalysts to make this reaction occur."
