We are trying to synthesize (using hydrothermal synthesis) and use Ag-based materials (such as AgBr, Ag3PO4 ) as photocatalysts...the photodegradation tests are promising, but unfortunately we have some stability issues regarding the re-useability/stability of the above-mentioned materials.
Are there any synthesis "tricks", additives which can increase the (photo)stability of these materials?

: thank you very much for your "deep" answer...we'll try to adopt hopefully! ...but...if I"'m coating it with something (SC) than the Ag-based material how will be involved directly in the photocatalytic process? (the interface no more being in contact with the solution we want to degradate)...but if anyone else has other ideas...don't hesitate to write here! :D

: sorry for disturbing you...but can you put me on way with some publications about this approach?Thank you in advance! :D
Dear Kovacs Gabor
These drawback of Ag based photocatalyst such as Ag3PO4 was also founded in my research group when synthesized Ag3PO4 with co-precipitation, hydrotermal synthesis or others. However, some study literatures said that the stability and photocatalytic activities of Ag-based photocatalyst (in Ag3PO4) increased by combining them to be a composite form with some semiconductor or electron/hole transporting materials such as graphene or graphene oxide, iron oxide, TiO2, etc. These is very useful to prolonging the lifetime of electron and inhibiting it from the photocorrosion of Ag metal of Ag3PO4 photocatalyst under visible light irradiation. May it help you.
