Opening the doors to efficient hydrogen production from solar energy (IMAGE)
Caption
New research advances open the door to efficient hydrogen production from solar energy – without using the scarce metal platinum. In the reactor at a chemistry laboratory at Chalmers University of Technology, Sweden, it is easy to see with the naked eye how hydrogen gas is formed through photocatalysis. When a lamp, simulating sunlight, is directed at a beaker of water containing nanoparticles of electrically conductive plastic, small hydrogen gas bubbles almost immediately begin to rise through the water. The gas is then guided through tubes to a hydrogen storage container, where the amount of hydrogen produced can be read in real time.
