Gas fixation solar cell using gas diffusion semiconductor electrode

摘要

A gas diffusion semiconductor electrode and solar cell and a process for gaseous fixation, such as nitrogen photoreduction, CO2 photoreduction and fuel gas photo-oxidation. The gas diffusion photosensitive electrode has a central electrolyte-porous matrix with an activated semiconductor material on one side adapted to be in contact with an electrolyte and a hydrophobic gas diffusion region on the opposite side adapted to be in contact with a supply of molecular gas.
