DESCRIPTION:Abstract: Sunlight is the starting point of life. Without the 
 sun\, our planet would be cold and lifeless. After the 1973 oil embargo\, 
 there was a resurgence of interest in solar energy. Making energy useable 
 is a central problem of our civilization. In theory\, photocatalytic cells
  are easy to make. Simply put the catalyst in water\, irradiate with sunli
 ght\, collect the hydrogen\, and there you are. In addition to the energy\
 , a variety of environmental problems now affect our entire world. A promi
 sing approach for remediating air quality contaminants is to employ photoc
 atalyst that oxidize these compounds. By definition\, photocatalyst is a c
 atalyst that accelerates photoreaction. Everything depends on the photocat
 alyst which must use sunlight efficiently. My research has now developed a
  new photocatalyst that works when irradiated with visible light. This pre
 sentation will provide an overview of my present and future of research.
