文摘

A novel PW/RGO/Ag NPs film with uniform morphology was facilely self-assembled. The film could be used as a SERS probe for selected detection of formaldehyde. The synergic interaction between RGO and Ag NPs can enhance the activity of the film. The detection limit for formaldehyde can reach about 10−8 mol L−1.
