摘要:
To halt the buildup of carbon dioxide (CO2), the main greenhouse gas, the development of an alternative energy source to fossil fuels becomes more and more important. Hydrogen (H-2) has the potential to meet the requirements as a clean non-fossil fuel in the future, if it can be produced using our primary source of energy, the sun, and stored and transported safely. The present article will give a short review on different approaches on semiconductor-based photoelectrochemical water splitting into hydrogen and oxygen (O-2) using sunlight as the energy input, also generally described as photoelectrolysis.
