Understanding the Mechanochemical Synthesis of Mixed Oxi j1es using Synchrotron and Neutron Techniques

机械化学合成混合氧化物是JM感兴趣的，是制造催化剂和吸附剂的潜在新途径。使用这种方法有很多优点，比如降低能耗和简化工艺流程表。然而，在机械作用下，试剂向活性相转变的机理尚不清楚，需要了解磨矿技术、时间、初始试剂比和添加剂的存在等关键参数。需要了解在铣削过程中形成的相（非晶和结晶）以及如何优化工艺。该项目将使用断层扫描、PDF、XAS、XRD、拉曼中子技术来了解钙钛矿或钼酸盐等氧化物随磨矿时间和关键参数的机械化学转变机理。还将发展就地技术。

The mechanochemical synthesis of mixed oxides is of interest within JM as a potential new route to the manufacture of catalysts and absorbents. There are advantages from using this route such as reduced energy and simplified process flow sheets. However, the mechanism of the transformation of reagents to active phases under mechanical action is not well understood and knowledge of how key parameters such as milling technique, time, initial reagent ratios and the presence of additives is needed. Knowledge is required of which phases (amorphous and crystalline) form during milling time and how the process can be optimised. The project will use tomography, PDF, XAS, XRD, Raman neutron techniques to understand the mechanism of mechanochemical transformation with milling time and key parameters for oxides such as perovskites or molybdates. In situ techniques will also be developed.
