In order to get materials with enhanced adsorption and organic transformation performance, nanosized Ag-Pt nanoparticles loaded
was prepared by sol-gel method. This catalyst was characterized by X-ray diffraction(XRD) and atomic force microscopy(AFM). Ag-Pt-
catalyst induces the reaction of condensation of indole and aldehyde to give bis-(indolyl)methanes in strikingly lesser time under microwave irradiation.
