I have synthesised Au-Ag nanoparticles. I want to determine the composition of Au & Ag separately in the bulk and at the surface. How effective would it be to use STEM EDX for this?
I have synthesized Au-Ag alloy NPs in colloidal form by reducing HAuCl4 and AgNO3 using NABH4 with ATP as capping agent. I want to add a support, Silica MCM-41 to the prepared NPs. What should be...
