Progress in Solar Photocatalytic Hydrogen Production

With the rapid development of human society and dramatically consumption of traditional energy, energy shortage and environmental pollution have become an important factor restricting the sustainable development of human society. At present, the development of clean and environmentally friendly renewable energy system has drawn much attention and becomes an important priority stratagem in the world. In many green and sustainable new energy projects, semiconductor-based photocatalytic hydrogen production technology which utilizes the available clean and renewable solar energy to prepare clean hydrogen energy is excepted to solve the crisis of energy shortage and environmental pollution, has become one of the most promising applied technology for the world. This paper reviews briefly semiconductor-based photocatalytic hydrogen production technology by introducing principles of photocatalytic water splitting, photoelectrochemistry of semiconductors and semiconductor electrode stability and photocatalytic hydrogen production efficiency. Some recent advances in semiconductor photocatalyst, photogenerated charge separation and photocatalytic hydrogen production system are highlighted. The existing problems and further development in this field are also proposed. The development of solar photocatalytic hydrogen production technology is commented and prospected.
