Description

<p>We describe the development of the nano-size CdS catalyst having stratified structure that efficiently separates electron and hole during photolysis. In a way, the stratified structure enabled the production of a reaction system that resembled the one in biological cells. Furthermore, using this catalyst along with materials such as, calcium hydroxide, seawater and H2S, we succeeded in producing about 7.5 l/h m2 of hydrogen gas under the sunlight. In the near future, this system will be applied for a harmless technology of hydrogen sulfide and at the same time, a production method of hydrogen with hydrogen sulfide generating in a sewage disposal plant.</p>
