An iron-containing phyllosilicate clay mineral is presented as the first example of a naturally occurring photocatalyst for hydrogen evolution from water. Sodium-proton ion exchange and immobilization of Pt nanoparticles were examined to boost photocatalytic hydrogen evolution. Clay and the clay based photocatalysts exhibited high stability upon photocatalytic recycling tests.
