Green Ag/AgCl as an Effective Plasmonic Photocatalyst for Degradation and Mineralization of Methylthioninium Chloride

A green synthesis of Ag/AgCl with an exceptional SPR and photocatalysis property is greatly benefit to the environmental application especially pollutant removal. In this work, a novel plasmonic nanocatalyst using aqueous garlic extract (Allium Sativum L.) was successfully synthesized. The allicin organosulfur compounds in can act as reducing agents process. properties were characterized by scanning electron microscopy (SEM), transmission (TEM), X-ray diffractometer. light-harvesting investigated UV-vis absorption spectra which reveals its visible light capability owing surface plasmon resonance behavior Ag nanoparticles. degradation mineralization methylthioninium chloride (MC) photocatalyst evaluated under natural solar irradiation. Surface nanoparticles presence from facilitated adsorption MC onto particle surface, promoting greater degradation. photocatalytic reaction be explained pseudo first-order pattern highest rate 0.5829 mg L?1 min?1 at pH 10. activity sunlight reached 90% 75% for total organic carbon (TOC), respectively. intermediate products detected during irradiation before final transformation CO2, H2O, HNO3, H2SO4 also reported. simplicity offer convenience applying these removal water treatment processes.
