How can we produce clean hydrogen without burning fossil hydrocarbons or other non-renewable energy sources? We can do so through photoelectrochemistry, or artificial photosynthesis, a method that—just like photosynthesis—uses sunlight and water, as with electrolysis, to obtain hydrogen, without generating harmful emissions. A group of researchers from the Department of Physics of the University of Trento has focused precisely on this approach.
The research is published in the journal Carbon.
One of the most innovative aspects of their research project is the use of photocatalysts (semiconductor materials) based on two-dimensional materials, and in particular, on graphitic carbon nitride (g-C3N4). This material is lightweight…
