Facile Synthesis of Fe₃O₄@Tannic Acid@Au Nanocomposites as a Catalyst for 4-Nitrophenol and Methylene Blue Removal.

ABSTRACT: A facile, cost-effective, and eco-friendly method was proposed to synthesize Fe₃O₄@tannic acid@Au nanocomposites (Fe₃O₄@TA@Au). First, Fe₃O₄ nanoparticles with diameters of 20 and 200 nm were synthesized by co-precipitation and solvothermal methods, respectively. Gold nanoparticles were deposited on magnetic Fe₃O₄ through tannic acid-metal-polymer intermediate-layer-mediated reductions. The catalytic activities of the as-prepared Fe₃O₄@TA@Au were investigated by spectroscopically monitoring the reduction of 4-nitrophenol (4-NP) and methylene blue (MB), which could be achieved within several minutes with an excess of NaBH₄. The impact of the Fe₃O₄ si
