Photocatalysis
An example of organometallic research is mimicking photosynthesis. Photosynthesis is the process that plants use to make sugar for food. Plants use only carbon dioxide gas from the air, water and sunlight. Plants actually have an organometallic molecule containing Mn that helps them perform this reaction.  Scientists hope to make an organometallic molecule that can make organic products like fuels using only carbon dioxide, water and light. If this process could be harnessed it could dramatically reduce pollution, because the carbon you make your fuel with is the carbon dioxide from the air.
