A natural, iron-containing clay can be used as a photocatalyst for generating hydrogen from water using light.
Photocatalysis that uses sunlight to split water and thereby generate hydrogen gas is a highly attractive way to generate green energy.
Much research has been done in exploring various photocatalysts for the process. Along with a high photoactivity, desirable properties include environmentally-friendly materials that are stable, cheap and easy to process.
Now, a team led by researchers from Vidyasirimedhi Institute of Science and Technology (VISTEC) in Thailand has found that a natural, iron-containing clay can be used as photocatalyst to release hydrogen from water.
This is the first time that a naturally occurring photocatalyst has been found for hydrogen evolution. In addition to being eco-friendly, the photocatalyst exhibited good stability in recycling tests.
