Biodirected synthesis of Ag-Ni alloy nanoparticles from marine algae (cladophora) and it's application in photocatalytic degradation of crystal violet

In bio organisms algae is one of the important source of reducing and capping agents for the synthesis of bimetallic nanoparticles (NPs) due to simple procedure and inexpensive cost required. This paper reports the biosynthesis of Ag-Ni alloy bimetallic NPs by using marine algae (Cladophora) as reducing and capping agent. The morphology, size and composition of Ag-Ni NPs were confirmed by scanning electron microscope (SEM), energy dispersive x-ray analysis (EDX) and transmission electron microscopy (TEM) analysis. The biosynthesized Ag-Ni NPs was used for the photoctalytic degradation of environmental pollutant crystal violet under solar light. The optimum conditions for the degradation were measured with UV-Visible spectral analysis. Due to the smaller size of Ag-Ni NPs exhibit great photocatlytic performance.
