Engineering of spinels for catalysis

本研究计划的目标是开发微波或感应场辅助催化技术，利用磁性尖晶石进行非均相气相反应。创新是利用这样一个事实，即只有纳米颗粒上的反应位点需要处于更高的温度下，以提高表面反应的效率和活性。这种方法将能够快速加热到给定的再生温度并使烧结最小化。拟议的5年研究项目旨在合成，表征和研究各种尖晶石铁氧体的纳米结构，即MxFe 3-xO 4，其中M = Ni，Co，Mn，Zn或其混合物。由于具有磁性且对微波敏感，这些纳米材料被认为是用于生产适用于辅助催化的混合纳米结构的构建块。

The goal of the research program is to develop the technology of microwave or induction field assisted catalysis using magnetic spinels for heterogeneous gas-phase reactions. The innovation is to take advantage of the fact that only the reaction site on the nanoparticles needs to be at higher temperature to improve the efficiency and activity of surface reactions. Such process would enable fast heating to a given regeneration temperature and minimize sintering. The proposed 5-year research project intends to synthesize, characterize and study nanostructures of various spinel ferrites, namely MxFe3-xO4, with M = Ni, Co, Mn, Zn or mixture thereof. Being magnetic and susceptible to microwave, these nanomaterials are being considered as building blocks for producing hybrid nanostructures adapted for assisted catalysis.
