Bimetallic Fe nanoparticles: Recent advances in synthesis and application in catalytic elimination of environmental pollutants

摘要: Abstract As an emerging new class of materials comprising two different metals, bimetallic nanoparticles (NPs) exhibit functions because the synergistic rather than merely additive effects metals. Compared with monometallic Fe NPs, NPs have markedly enhanced physical and chemical properties, including magnetism reducing ability. However, controlled morphology, size, composition, structure are often difficult to synthesize. This review summarizes recent advances in synthesis environmental application NPs. Different methods synthesizing structures, sizes, compositions, surface properties summarized. Focus is also given catalytic elimination various pollutants using they emerged as a promising catalyst for remediation. Their strong ability can be used remove numerous (e.g., heavy halogenated organic compounds, nitro azo oxyanions). Reactions between these mainly fall into four categories: (1) replacement reaction heavy-metal removal, (2) hydrodehalogenation hydrocarbons, (3) hydrogenation (4) hydrodeoxygenation oxyanions. considerable separability degrade nonbiodegradable pollutants.
