PEC cells use solar energy to split simple and safe compounds such as water into hydrogen and oxygen, hydrogen being a high-energy fuel that can be stored and used as needed.”Despite the promise, PEC cells are not yet a practical solution to the energy crisis because of the scientific bottlenecks such as the sluggishness of the water-oxidation process. Catalysts are used to activate the water-splitting process but these catalysts are expensive metals such as platinum, iridium and ruthenium, among others, which render the cells impractical,” said Mohammad Qureshi, Professor, Department of Chemistry at IIT-G, in a statement.
