项目摘要

Nanomaterials, with their high surface areas and unique properties are revolutionising many areas of science and technology. The microbial production of metallic nanomaterials by biotechnological routes has been a focus of research in DEES, Manchester for more than a decade, with wide commercial potential has been demonstrated. The bacterial systems developed are scalable, tunable and amenable to genetic manipulation, and can therefore be used to host recombinant enzymes, producing novel "biometallic catalysts". Development of these metal/enzymatic catalysts has the potential to deliver new routes to novel or better catalysts, including from waste materials or solutions (revalorising these waste streams). This project will examine the use of harmless subsurface metal-reducing bacteria to produce catalytically active nanoparticles from a range of metals and their bimetallic combinations. A cross-disciplinary approach will be adopted, including microbiological manipulations combined with high quality nanomaterial characterisation. The focus of activities with the iCASE partner JM will include examination of the products as catalysts but other possible applications of the technology will be considered as the project progresses. The student will therefore gain practical knowledge of the use of bacteria to produce nanoparticles, the chemistry of a number of d-block metals, techniques used to characterise nanomaterials, and heterogeneous catalysis.

纳米材料，以其高表面积和独特的性能正在革命性地改变许多领域的科学和技术。通过生物技术路线微生物生产金属纳米材料已经成为曼彻斯特DEES十多年来的研究重点，具有广泛的商业潜力。所开发的细菌系统是可扩展的、可调节的并且适合于遗传操作，并且因此可以用于宿主重组酶，从而产生新型的“生物催化剂”。这些金属/酶催化剂的开发有可能为新型或更好的催化剂提供新的途径，包括从废物或溶液中提取（重新评估这些废物流）。该项目将研究使用无害的地下金属还原细菌从一系列金属及其混合物中生产催化活性纳米颗粒。将采用跨学科方法，包括微生物操作与高质量纳米材料表征相结合。与iCASE合作伙伴JM的活动重点将包括对产品作为催化剂的研究，但随着项目的进展，将考虑该技术的其他可能应用。因此，学生将获得使用细菌来生产纳米颗粒，一些d区金属的化学，用于纳米材料的化学技术和多相催化的实用知识。
