Dye decolorization test for the activity assessment of visible light photocatalysts: Realities and limitations

The layered double hydroxide route to Bi–Zn co-doped TiO2 with high photocatalytic activity under visible light

“…Although this test allows a first evaluation and comparison, one should be aware of the possible limitations of such test [65]. Fig.…”

Probing the activities of UV and visible-light absorbing photocatalyst powders using a resazurin-based photocatalyst activity indicator ink (Rz Paii )

“…In summary, although dyes can be used as a method for testing photocatalyst activity, great care needs to be taken to ensure that the incident excitation light is NOT absorbed, or absorbed very weakly, by the dye itself [19].…”

One-pot synthesis of a TiO2–CdS nano-heterostructure assembly with enhanced photocatalytic activity

“…For quite some time now, development of novel functional 15 materials has been primarily driven due to their constant demand in renewable energy and sustainable environment. 1 Design of materials via ambient or near ambient temperature synthesis methods for various applications is at the forefront of research interest worldwide.…”
