No single answer. It depends on intimate constitution of the nanoparticles. Some can act anyway as catalysts (not photocatalysts) and others don't.

Priyanka Uddandarao

Federico Svarc ...Thank you for the answer. I am looking in the case of chalcogenides mainly ZnS, CuS, NiS

Miao Kan

If you mean the large and active surface, they are also active in other types of catalysis, such as electrocatalysis and thermocatalysis.
