Facile low temperature synthesis of bismuth molybdate stabilized ferricyanide and ferrocyanide nanocomposites for the degradation of organic pollutants

Recently, the development of environment friendly and green solutions to remediate water resource pollution has received global attention. Bismuth molybdates are considered among the most intriguing materials, due to their unique characteristics and emerging demands, such as ion conductors, photoconductors, sensors and photocatalysts. Owing to their outstanding employment, we aimed to fabricate the visible light active bismuth molybdate stabilized ferricyanide and ferrocyanide nanocomposites. The structural and spectrophotometric results indicated that, as fabricated composites possessed an orthorhombic crystal structure and the band gap energy of 2.80 and 2.78 eV respectively. The nanocomposites were synthesised through one step hydrolysis method. The nanocomposites were tested to lab-scale photodegradation of methyl orange (MO) and Phenol, under visible light irradiation. The photocatalytic results demonstrated that the coordination complex of Bismuth Molybdate (BMO)/Ferricyanide and Bismuth Molybdate (BMO)/Ferrocyanide in the present study showed much enhanced photocatalytic performance as compared to Pristine BMO. The degradation results of both the nanocomposites are almost 1.5 times higher than that of reported pristine Bi2MoO6 (BMO).
