Processing characterisation novel self assembled

项目摘要

The aims of this project are to process and characterise self assembled heterocatalysts using a novel technique, known as DNA Origami. This should produce platinum catalysts of the required nanoscale structure with an enhanced stability. The proposed research objectives are:1. To process and produce self assembled heterocatalysts using DNA strands as the catalyst support in the initial processing stages via a technique known as DNA origami. 2. To convert the DNA support into a carbon based support via a graphitisation process, to make the product properties more suitable for its potential application i.e in fuel cells for the generation of power. 3. To explore the optimisation of the processing method by investigating the influence of process parameters such as temperature, pressure or the type of buffer employed on the final product attributes measured. In addition, improved purification techniques can be studied to increase the final product quality and enable higher product recovery. 4. The final product properties can be measured using appropriate characterisation methods such as X-ray studies, chemisorption techniques (to determine the platinum metal dispersion in structure) and Transmission Electron Microscopy or Scanning Electron Microscopy to observe the morphology of the catalyst structure. The physical and chemical properties of the catalyst product can be measured using spectroscopic techniques like infra-red spectroscopy. 5. The product properties and morphology results can be compared to those of a traditional heterocatalyst and the processing method can be optimised accordingly to enable the establishment of a nano-heterocatalyst product with the desired attributes.

该项目的目的是利用一种被称为DNA折纸的新技术来处理和表征自组装的异催化剂。这将产生所需的纳米级结构的铂催化剂，并具有更高的稳定性。拟定的研究目标是：1。通过DNA折纸技术，在初始加工阶段利用DNA链作为催化剂载体，加工和生产自组装异催化剂。2. 通过石墨化工艺将DNA支架转化为碳基支架，使产品性能更适合其潜在应用，即用于发电的燃料电池。3. 通过研究工艺参数（如温度、压力或使用的缓冲液类型）对最终产品属性测量的影响，探索加工方法的优化。此外，可以研究改进的净化技术，以提高最终产品的质量，并实现更高的产品回收率。4. 最终产物的性质可以使用适当的表征方法来测量，如x射线研究、化学吸附技术（以确定铂金属在结构中的分散）和透射电子显微镜或扫描电子显微镜来观察催化剂结构的形态。催化剂产品的物理和化学性质可以用红外光谱等光谱技术来测量。5. 产品的性能和形貌结果可以与传统的异催化剂进行比较，并可以相应地优化加工方法，从而建立具有所需属性的纳米异催化剂产品。
