Synthesis and applications of Au-Ag bimetal impregnated layered manganese oxide nanocomposite

In present study, gold and silver metal nanoparticles were prepared and pillared on the manganese oxide octahedral molecular sieve type layered material. This method helps to stabilize the metal nanoparticles and for the synergetic catalytic effect of both manganese oxide and noble metal catalyst towards catalysis. Formation of layered manganese oxide in pure form and with pillaring was confirmed by XRD. Surface topology and chemical state were studied by SEM with EDS, TEM and XPS respectively. Batch studies have been conducted to evaluate the catalytic oxidative degradation of methylene blue dye using AuAg@LMO
