Effect of synthetic methods on the characteristics and performance of IrO2 catalysts

Abstract

For many years fossil fuel has been the primary source of energy worldwide though, the environment is negatively affected because of the high carbon dioxide (CO2) emissions associated with the use of fossil fuels. Hydrogen (H2) is known for its ecological cleanliness and high energy efficiency. More consumers are considering H2 as an energy carrier for different stationery and transportation applications. The most sustainable way to synthesize H2 is by using the water electrolysis method with renewable energy sources like solar, wind, etc. Currently, the proton exchange membrane water electrolyzer (PEMWE), coupled with renewable energy sources, is the most efficient water electrolyzer technology to produce very pure H2 with no CO2 emissions.
