Highly Stable Metal Oxide-Based Heterostructured Photocatalysts for an Efficient Photocatalytic Hydrogen Production

The need for fuel generated by renewable resources has become important in the global scenario. Solar energy is an abundantly available renewable resource for the earth. There is a huge potential for H2 derived from clean energy resources for commercial applications such as generation of electricity, fuel for transportation, domestic usage, rocket propulsion, etc. With H2 as a fuel, a zero-emission process using fuel cells produces electricity with only water as the by-product. Global demand for hydrogen (H2) as an energy carrier is steadily increasing. Researchers are therefore working towards the development of efficient materials for hydrogen (H2) production by solar photocatalysis. For efficient H2 fuel production, development of novel/modified photocatalysts that are efficient, stable and recyclable remains a challenge.
