Solar Fuel: Hydrogen Generation Using Plasmonic Resonance

This research takes on the challenge of clean fuel production using sunlight and water. The research focus on the use of plasmonic resonance to initiate thermochemical reactions in metal oxides. The thermochemical process comes in two stages; firstly at the high temperature stage (> 1000 oC) the metal oxide catalyst undergoes reduction whereby oxygen is released, and in the second stage (lower temperature) water is made to contact with the catalyst and the oxygen from the water molecule is captured by the metal oxide and hydrogen is released. The conundrum is the high temperature required to split water, however, using the plasmonic resonance this high temperature condition is not required. The metal oxide support for such reactions is not well understood.
