The present study is focused on the photodegradation of rhodamine B using aqueous free-basephotocatalysts in presence of solar radiation. All catalysts such as free-base tetrasodiummeso-tetra(p-sulphonatophenyl)porphyrin (TPPS4) or abbreviated as TPS and substituting M = Co,Ni, Cu, Zn and Ag into the moiety of TPS to get metalloporphyrins, were synthesized. Further, theywere characterized by UV-visible, IR and 1H MMR spectroscopic techniques. The photodegradationof rhodamine B of concentration 10-5 M was carried out with 5 mg of a photocatalyst of free-base andother metalloporphyrins. It was observed that these synthesized photocatalysts have shown thephotodegradation efficiency to the extent of 100% within time period of 5 to 40 min. The process ofdegradation was verified with HPLC and ion-chromatography
