Scientific American's 2006 researcher of the year, M.I.T.'s Angela Belcher, has engineered a virus so that it captures light energy and uses it to catalyze the splitting of water, a first step in a possible new way to generate hydrogen for fuel cells.
One key step is splitting water, or water electrolysis.
Because producing oxygen from splitting water is a barrier to using artificial photosynthesis (the splitting of water into H ₂ and O ₂ as a renewable energy, many research programs focus on designing catalysts that assist with this oxygen - producing step.
Kaspar and her team are now conducting photoelectrochemical studies to take the next step: split water to produce fuel.
Photosytem II utilizes a water - splitting manganese - calcium enzyme that when energized by sunlight catalyzes a four photon - step cycle of oxidation states (S0 - to - S3).
Going back to Equation 1, as mentioned above, catalysts are needed to efficiently split water because all water - splitting schemes require the inefficient step of producing oxygen.
The team figured out the steps that occur when a catalyst helps split an alcohol, generating water and a carbon - based molecule known as an alkene.
Superimposed on that are rectangles showing four steps of photosynthesis in extreme close - up: molecules of water going into the roots; yellow dots of sunlight filling a green chlorophyll vessel; energy emanating from one side of the chlorophyll vessel and splitting the water into two separate streams of oxygen and hydrogen; and energy emanating from the other side of the chlorophyll vessel, which demonstrates how the sun's energy is «trapped as little packets.»
The material is called synthetic molybdenum - sulphide and it goes a step beyond just being an excellent sponge for moisture, it also acts as a semi-conductor and catalyses the split of water molecules into oxygen and hydrogen.
A key step in both natural and artificial photosynthesis is the splitting of water into its constituents, hydrogen and oxygen.
Latest examples include solar water splitting using ferrites at 100 kWth power level [3] and subsequent scaling up to 750 kWth at the Plataforma Solar de Almería (PSA); thermal dissociation of ZnO as part of the two - step ZnO / Zn cycle in a 140 kWth solar reactor at the MegaWatt Solar Furnace in Odeillo, France [4]; and steam gasification of low - grade coal and carbonaceous waste in a 150 kWth solar pilot plant at PSA [5].
The big step to clean energy has to be via hydrogen generated by sunlight using one or more catalysts, seven different ones have been reported in past 2 years, to split water.
We can also use thermochemical cycles, such as the sulphur - iodine cycle, that use a sequence of chemical steps to split water.
