With the ever-expanding need for renewable energy sources growing, much time and energy is allocated to finding new and innovative technologies. Current membrane reactors focus on a specific class of photocatalyst or are limited to air purification only. This approach does not take into consideration a broader range of the electromagnetic spectrum, and often creates a narrow design in function.
ASU Researchers have developed an integrated reactor design for photocatalytic water splitting. This design at ASU has coated fiber optics and flexible polymeric membranes for enhanced adaptability. Researchers enhanced the ability of such a reactor by allowing it to function with the use of multiple light sources. This is accomplished through the utilization of immobilized photocatalysts, tuned to absorb the energy from the particular light source. The incorporation of hollow-fiber, spiral wound PEM elements allows for water splitting setups to be made into compact modules. Researchers at ASU have focused on inventing a system that is multifaceted. This new system has applications in both energy generation and water purification. Innovative in its design through the use of fiber optic cables coupled with Proton Exchange Membranes (PEM), this reactor system can cover a larger area of utility and purpose.
