Figure 2. (IMAGE) Kobe University Caption (a) The design of the novel nanosheet-laminated photocatalytic membrane, which uses two types of nanosheet, each with different functions. (b) Changes in the relative water permeation speed of the photocatalytic membrane before and after photoirradiation. Bovine serum albumin (BSA) was used as the foulant. The performance of two different membranes was compared: a niobate (HNb3O8) nanosheet-laminated membrane and a composite niobate nanosheet/carbon nitride (HNb3O8/g-C3N4) nanosheet-laminated membrane.
