Slurry photoreactors
WebbThere are many diverse photoreactor types, including immobilized photoreactors, photocatalytic membrane reactors (PMRs), and hybrid membrane slurry photoreactors. These were designed to help resolve problems mentioned above, but they su er from technical drawbacks such as catalyst e ciency and membrane fouling/scaling [16].
