On the way to sustainable hydrogen

Researchers in the SNI network have developed a theoretical method to analyze and optimize water splitting by exploiting optical effects. The work, published in the Journal of Physical Chemistry C, will help to advance sustainable hydrogen production without emitting CO2.

Theoretical calculations were used to calculate the light intensity distribution during the splitting of water. A photoelectrode made of bismuth vanadate (BiVO4) structured with silver nanoparticles on its surface was used. The silver nanoparticles help to concentrate more light in the photoelectrode (light blue areas). They are surrounded with a silica shell to protect the silver from corrosion in water (Image: L.
