Abstract

Due to the increase of the worldwide demand for energy along with the global warming and the increasing level of atmospheric CO2, solar hydrogen has been proposed as an optimal fuel as it can be produced from water using solar energy which emerges as the most promising energy source in terms of abundance and sustainability. So far the main commercial process for producing hydrogen is steam reforming of hydrocarbons which is connected with a CO2 emission disadvantage. Carbon free hydrogen production can be achieved by water splitting through an electrolyser powered by photovoltaics, but a potentially more cost effective route is to perform direct photocatalytic water splitting using semiconductor photocatalysts. Herein, the authors will present the principles of this process, the current progress in the field, and future challenges.
