Abstract Copper nanoparticles (Cu‐NPs) have a wide range of applications as heterogeneous catalysts. In this study, novel green biosynthesis route for producing Cu‐NPs using the metal‐reducing bacterium, Shewanella oneidensis is demonstrated. Thin section transmission electron microscopy shows that are predominantly intracellular and present in typical size 20–40 nm. Serial block‐face scanning demonstrates well‐dispersed across 3D structure cells. X‐ray absorption near‐edge spectroscopy...
The microbial synthesis of biominerals offers a potentially sustainable green solution for the production wide range industrially relevant functional nanomaterials. Metal-reducing bacteria are particular relevance, as they can enzymatically reduce spectrum high oxidation state metals and metalloids, forming cell-templated nanomagnets, catalysts, remediation agents quantum dots. Although these bioprocesses have been shown to be both scalable tunable (with respect particle size, reactivity,...
Iron nanoparticles are a promising new technology to treat contaminated groundwater, particularly as they can be engineered optimise their transport properties. Technetium is common contaminant at nuclear sites and reductively scavenged from groundwater by iron(II). Here we investigated the potential for range of optimised iron remove technetium groundwater/sediment systems. Nano zero-valent Carbo-iron stimulated development anoxic conditions while generating Fe(II) which reduced soluble...
Biogenic magnetite nanoparticles were employed to recover copper from whisky distillery wastewaters, generating an efficient and reusable click chemistry catalyst.
Abstract Engineered nanoparticles offer the potential for remediation of land and water that has been contaminated by organics metals. Microbially synthesized nano-scale magnetite, prepared from Fe(III) oxides subsurface Fe(III)-reducing bacteria, offers a scalable biosynthesis route to such reagent. To underpin delivery “bionanomagnetite” (BNM) nanomaterial during in situ treatment options, we conducted range batch column experiments assess optimise transport reactivity particles porous...
